Things are a lot brighter after the surgery.  Actually the biggest and first thing I noticed was after getting one eye done, was the color white in the corrected eye was deep beige in the uncorrected eye.  Or simply stated, how BRIGHT and Clean white actually was!

Yes, there a lot more stars in the sky and they are brighter after my surgery.  And they come out to see me earlier.  But younger eyes still are better.

I had the single correction lens for being near sighted correction in each eye to 20/20.  I did not do the one for near and other eye for far sighted (how would that work for binocular?).  The third option when I had mine done was a multifocal lens.  I had heard at that time, that some people had spikes and halos with those lens.  So I went for the simpler and cheaper (Medicare covered 100%) solution.  I am happy with that decision, for that time.  But things in medicine are always improving, make your best informed decision for yourself at the time you get it done!

I still need reading glasses, and  for winter nights when keeping your ears warm is a concern, I found nose pincher reading glasses on a chain are good option.

Both Stu and George are older than I am, but I have had L3,4 and 5 fused in my back and have gained a little (a lot) of weight.  I do not carry a bucket camp chair any more, I use a directors chair that you can get at Harbor Freight on sale for $20.  The bucket chair where your rump is lower than your knees is a real pain getting up from.  I would like to find a source for a good set of grabbers.  Seems like I am dropping more the older I get, or is it just harder to pick up those things.

I have heard from several people that they were quite happy with the results. Of course any surgery is always a risk and you have to weigh risk vs reward. That is why I have waited so long. The way I fugue I am fine for everyday use but I know that is going to change soon so what the heck lets give it a go. Waiting till later age will only lessen the chance as old people do not do as well as younger folks. Of course at 67 I can't claim to be young at the moment. I hear you though.

OMG was it cold last night. I just woke up with a huge headache and feeling like Boris Karloff in the Mummy due to no humidity in the air.

We had a really nice session last night despite a complete blanket of clouds in the early evening. It cleared as darkness descended and the temperature dropped Emoji. I had on all my winter gear save my arctic books, which I later regretted not bringing with me. You don't associate surplus Korea cold weather boots with observing just a week before May. I think the humidity was something in the 30's during that session. Bone dry.

Seeing was excellent.  Kent and I saw quite a variety of double stars, some quite difficult. It has been a while since I devoted a night to doubles in a serious manner. One of the fun objects of the session was an interesting asterism composed of a triple star system inside another perfect trio of three stars lying in another orientation with respect to the triple star. I believe this has been termed "stargate" informally by some observers. Located in the Corvus and Crater constellations, this weird object form a further trio of three objects. This alrger grouping is formed of M-104, the strange "L" shaped asterism that point to the galaxy, which was visible despite the moon, and "stargate". These look for all the world as if they have been placed by an alien civilization for some celestial purpose foreign to anything on Earth. Most of us don't spend too much time down there in these southern constellations save to see M-104. Combined, all these objects form a weird grouping in a low power eyepiece. They are all the  more weird as they stand out in a suburban sky, isolated from any dimmer background stars.

I did get a look at the moon earlier in the evening and was able to apply higher powers of 384X and 408X. I was able to see the lunar volcano Hortensias Domes (A and B) close to Copurnicus. It is rare to be able to apply that kind of power as seeing usually will not support it. Last night though I could make out the summit pit (vent) of Hortensius A at 408X. I tried to see the rille going down the middle of Alpine Valley but could not see it despite my best efforts. This is hardly surprising as I have only seen this feature once in 30 years. I rate it as one of the most difficult observations to make on the moon.

When I really want to observe the finest lunar detail I use a Baader Prism diagonal in combination with an  Abbe orthoscopic eyepiece. Often I have been able to resolve very fine details which are invisible even in the best wide field eyepieces such as Pentax or Televue. These eyepieces were designed in 1880 by Ernst Abbe for use in microscopes. Telescopes and microscopes have a lot in common. Believe me I know, as much of my junior year in college was spent with my orbs glued to a polarizing microscope while taking mineralogy and petrology. I think I have rings like a racoon around my eyes from that year.

One distressing thing that was apparent last night is the deterioration of my eyes due to cataracts. Age has caught up with me there and it is time for surgery now.  The moon always has a ring of haze around it now and my dominant eye, the left, is no longer as sensitive to dim objects as my right eye is. This has been coming on for some time now and it has reached the point where action is required. I have compensated with a lot of observing experience up to this point but now things are coming to a head.

This alrger grouping is formed of M-104, the strange "L" shaped asterism that point to the galaxy, which was visible despite the moon, and "stargate". These look for all the world as if they have been placed by an alien civilization for some celestial purpose foreign to anything on Earth. Most of us don't spend too much time down there in these southern constellations save to see M-104. Combined, all these objects form a weird grouping in a low power eyepiece. They are all the  more weird as they stand out in a suburban sky, isolated from any dimmer background stars.

I did get a look at the moon earlier in the evening and was able to apply higher powers of 384X and 408X. I was able to see the lunar volcano Hortensias Domes (A and B) close to Copurnicus. It is rare to be able to apply that kind of power as seeing usually will not support it. Last night though I could make out the summit pit (vent) of Hortensius A at 408X. I tried to see the rille going down the middle of Alpine Valley but could not see it despite my best efforts. This is hardly surprising as I have only seen this feature once in 30 years. I rate it as one of the most difficult observations to make on the moon.

When I really want to observe the finest lunar detail I use a Baader Prism diagonal in combination with an  Abbe orthoscopic eyepiece. Often I have been able to resolve very fine details which are invisible even in the best wide field eyepieces such as Pentax or Televue. These eyepieces were designed in 1880 by Ernst Abbe for use in microscopes. Telescopes and microscopes have a lot in common. Believe me I know, as much of my junior year in college was spent with my orbs glued to a polarizing microscope while taking mineralogy and petrology. I think I have rings like a racoon around my eyes from that year.

One distressing thing that was apparent last night is the deterioration of my eyes due to cataracts. Age has caught up with me there and it is time for surgery now.  The moon always has a ring of haze around it now and my dominant eye, the left, is no longer as sensitive to dim objects as my right eye is. This has been coming on for some time now and it has reached the point where action is required. I have compensated with a lot of observing experience up to this point but now things are coming to a head.

Never send an occultation observer to observe on rail road tracks. They are known for concentrating on the telescope and may not notice oncoming trains

Last night's twin occultation of the almost full moon.

There was a nice occultation of 65 Virgo (6th magnitude) by the moon. The phase of the moon was not quite full so I was curious as to how close the star would get to the terminator. This would show how much of the moon was not illuminated. It got a lot closer than I imagined before it disappeared. The moon is very close to completely full so the star got very close to the terminator. Not much hidden there. Usually we assume that full moon illuminates the entire visible face but actually full moon only lasts a very short time, hours at most. The terminator never stops moving so even on a "full moon night" something is always dark somewhere. The occultation gave a chance to accurately judge how much was till hidden (not much BTW). Less than I would have though as I said above.

At 2142 there was a second 6th magnitude star occulted to the same effect.

How precise are the predictions based on location? Well pretty good. Only a few miles can make a difference as Kent and I found out years ago while trying to observe a grazing pass. We could not see the graze from our location but only a few miles away another observer could see the graze. At 1/4 million miles distance to the moon you would not think a couple of Earth miles would make a difference but it does.

So the night turned out to be salvageable astronomically speaking. God the moon looks huge compared to the star. Sort of like the Star Wars death star approaching. I love occultations as they give you a sense of things in motion. Thank God they aren't normally observed on rail road tracks as it takes a bit of concentration and it could be fatal to occultation observers.

White light solar observation

jimcoble2000
 

There are six large sunspots connected by perhaps 4 to 5 small black pores. I haven't observed in white light for a while so I broke out my 4 inch and used a mylar front filter. The best views for solar detail is my Baader Planetarium Herschel Wedge but it is over with my 5 inch scope. I sort of hesitate to use the wedge on a Petsval system though it may indeed work fine. I know it works on a triplet or doublet refractor with no harm to the scope.

BTW the wedge can only be used with a refractor and not a reflecting telescope.

I have heard from several people that they were quite happy with the results. Of course any surgery is always a risk and you have to weigh risk vs reward. That is why I have waited so long. The way I fugue I am fine for everyday use but I know that is going to change soon so what the heck lets give it a go. Waiting till later age will only lessen the chance as old people do not do as well as younger folks. Of course at 67 I can't claim to be young at the moment. I hear you though.

Re: Observing last night in the arctic

As long as we’re making this a geezer convention, I might as well fess up too.  I’m  also thinking about cataract surgery. In my case, my dominant (right) eye is in much better shape, which is why I haven’t felt the need to pull the trigger yet.  But the doc says it’s getting to be that time. Not only is my left eye several magnitudes dimmer it also suffers from a macular pucker.  Makes my two eyes focus differently and really took some adjusting. Getting old is definitely not for sissies.

One distressing thing that was apparent last night is the deterioration of my eyes due to cataracts. Age has caught up with me there and it is time for surgery now.  The moon always has a ring of haze around it now and my dominant eye, the left, is no longer as sensitive to dim objects as my right eye is.

I have heard from several people that they were quite happy with the results. Of course any surgery is always a risk and you have to weigh risk vs reward. That is why I have waited so long. The way I fugue I am fine for everyday use but I know that is going to change soon so what the heck lets give it a go. Waiting till later age will only lessen the chance as old people do not do as well as younger folks. Of course at 67 I can't claim to be young at the moment. I hear you though.

I can identify with you about the eye problems and cataracts.  My dominant left eye is the worst, but my right eye is also less sensitive than it once was. When my Granddaughters Samantha and Chloe point out dim stars as they appear in the twilight, I just can't see them.  My eye doctor says he is ready to remove the cataracts, any time I am ready.

OMG was it cold last night. I just woke up with a huge headache and feeling like Boris Karloff in the Mummy due to no humidity in the air.

We had a really nice session last night despite a complete blanket of clouds in the early evening. It cleared as darkness descended and the temperature dropped Emoji. I had on all my winter gear save my arctic books, which I later regretted not bringing with me. You don't associate surplus Korea cold weather boots with observing just a week before May. I think the humidity was something in the 30's during that session. Bone dry.

Seeing was excellent.  Kent and I saw quite a variety of double stars, some quite difficult. It has been a while since I devoted a night to doubles in a serious manner. One of the fun objects of the session was an interesting asterism composed of a triple star system inside another perfect trio of three stars lying in another orientation with respect to the triple star. I believe this has been termed "stargate" informally by some observers. Located in the Corvus and Crater constellations, this weird object form a further trio of three objects. This alrger grouping is formed of M-104, the strange "L" shaped asterism that point to the galaxy, which was visible despite the moon, and "stargate". These look for all the world as if they have been placed by an alien civilization for some celestial purpose foreign to anything on Earth. Most of us don't spend too much time down there in these southern constellations save to see M-104. Combined, all these objects form a weird grouping in a low power eyepiece. They are all the  more weird as they stand out in a suburban sky, isolated from any dimmer background stars.

I did get a look at the moon earlier in the evening and was able to apply higher powers of 384X and 408X. I was able to see the lunar volcano Hortensias Domes (A and B) close to Copurnicus. It is rare to be able to apply that kind of power as seeing usually will not support it. Last night though I could make out the summit pit (vent) of Hortensius A at 408X. I tried to see the rille going down the middle of Alpine Valley but could not see it despite my best efforts. This is hardly surprising as I have only seen this feature once in 30 years. I rate it as one of the most difficult observations to make on the moon.

When I really want to observe the finest lunar detail I use a Baader Prism diagonal in combination with an  Abbe orthoscopic eyepiece. Often I have been able to resolve very fine details which are invisible even in the best wide field eyepieces such as Pentax or Televue. These eyepieces were designed in 1880 by Ernst Abbe for use in microscopes. Telescopes and microscopes have a lot in common.

Mark,

I can identify with you about the eye problems and cataracts.  My dominant left eye is the worst, but my right eye is also less sensitive than it once was. When my Granddaughters Samantha and Chloe point out dim stars as they appear in the twilight, I just can't see them.  My eye doctor says he is ready to remove the cataracts, any time I am ready.

OMG was it cold last night. I just woke up with a huge headache and feeling like Boris Karloff in the Mummy due to no humidity in the air.

We had a really nice session last night despite a complete blanket of clouds in the early evening. It cleared as darkness descended and the temperature dropped Emoji. I had on all my winter gear save my arctic books, which I later regretted not bringing with me. You don't associate surplus Korea cold weather boots with observing just a week before May. I think the humidity was something in the 30's during that session. Bone dry.

Seeing was excellent.  Kent and I saw quite a variety of double stars, some quite difficult. It has been a while since I devoted a night to doubles in a serious manner. One of the fun objects of the session was an interesting asterism composed of a triple star system inside another perfect trio of three stars lying in another orientation with respect to the triple star. I believe this has been termed "stargate" informally by some observers. Located in the Corvus and Crater constellations, this weird object form a further trio of three objects. This alrger grouping is formed of M-104, the strange "L" shaped asterism that point to the galaxy, which was visible despite the moon, and "stargate". These look for all the world as if they have been placed by an alien civilization for some celestial purpose foreign to anything on Earth. Most of us don't spend too much time down there in these southern constellations save to see M-104. Combined, all these objects form a weird grouping in a low power eyepiece. They are all the  more weird as they stand out in a suburban sky, isolated from any dimmer background stars.

I did get a look at the moon earlier in the evening and was able to apply higher powers of 384X and 408X. I was able to see the lunar volcano Hortensias Domes (A and B) close to Copurnicus. It is rare to be able to apply that kind of power as seeing usually will not support it. Last night though I could make out the summit pit (vent) of Hortensius A at 408X. I tried to see the rille going down the middle of Alpine Valley but could not see it despite my best efforts. This is hardly surprising as I have only seen this feature once in 30 years. I rate it as one of the most difficult observations to make on the moon.

When I really want to observe the finest lunar detail I use a Baader Prism diagonal in combination with an  Abbe orthoscopic eyepiece. Often I have been able to resolve very fine details which are invisible even in the best wide field eyepieces such as Pentax or Televue. These eyepieces were designed in 1880 by Ernst Abbe for use in microscopes. Telescopes and microscopes have a lot in common. Believe me I know, as much of my junior year in college was spent with my orbs glued to a polarizing microscope while taking mineralogy and petrology. I think I have rings like a racoon around my eyes from that year.

One distressing thing that was apparent last night is the deterioration of my eyes due to cataracts. Age has caught up with me there and it is time for surgery now.  The moon always has a ring of haze around it now and my dominant eye, the left, is no longer as sensitive to dim objects as my right eye is. This has been coming on for some time now and it has reached the point where action is required. I have compensated with a lot of observing experience up to this point but now things are coming to a head.

Thanks Stu
I have heard from several people that they were quite happy with the results. Of course any surgery is always a risk and you have to weigh risk vs reward. That is why I have waited so long. The way I fugue I am fine for everyday use but I know that is going to change soon so what the heck lets give it a go. Waiting till later age will only lessen the chance as old people do not do as well as younger folks. Of course at 67 I can't claim to be young at the moment. I hear you though. I hope that the intervening years have improved things.

Re: Observing last night in the arctic

Yes time catches all of us. I have only recently noticed it in the last six months. The moon even on a clear night now has a haze around it all the time.

It sneaks up on you slowly.

I first noticed it when I switched from my usual dominant left eye to the right. Stars that were on the edge of visibility in my left eye were easier in the right. It is not so simple an equation to figure in the loss of light. After decades of observing, my brain is trained to compensate when my normal left eye is used. I now naturally go to tricks such as averted vision and experience to unconsciously compensate for the loss. Now though it is getting past the stage of learned tricks. Those tricks just won't overcome the limitations at this stage.

I plan to have surgery in a few months. My ophthalmologist has been after me to do this for some time. In normal use my eyes are still fine but the telescope shows the problem now clearly. I can still detect faint stars with effort but that will get worse soon.

Much like our star parties and dark skies in general, nothing lasts forever no matter how much we fool ourselves. Maybe surgery can hold it off for a bit longer but ultimately it is a losing battle. This is not a downer as the trip has been worth all the cost; but that is the way of the world. There is still a bit left to go so I intend to continue on until it cannot withstand time anymore.
