Date   

Astronomy event FRIDAY, 23 April -- Any volunteers?

George Reynolds
 

Friday night from 8 to 10 pm I will be instructing a group of American Heritage Girls and Trail Life Boys and their leaders, showing them the Moon and some constellations (whatever is visible with a bright Moon).  These groups are alternatives to the GirlScouts and Boy Scouts.  They are working on their Astronomy merit badges.

I have plenty of handouts for them, and expect to see about two dozen girls and boys there.  I'll have my telescope, and my granddaughter Chloe will have hers, but we could use at least one more member with a telescope.  If you can come, try to be there to set up by 7:30 pm.  It is about a 50-minute drive from Virginia Beach (Bayside area).

Details of the event and driving instructions can be found on the BBAA calendar in Night Sky Network at this link:  






The weather forecast says it will be clear and cold, so dress appropriately.  

I hope we can have at least one more RSVP for this event.  It should be fun.

The sun today is quite good

jimcoble2000
 

The sun is ramping up and offers are rare view today of a large prominence rising off the surface at only a slight vertical angle directly below the observer. You can see the 3D structure from the base on the surface of the sun to the tip of the prom. Normally you see the proms in profile coming off the limb or as filaments that look like lines on the surface of the sun. This one is at the perfect angle to see the entire structure from bottom to top only slightly off vertical. A very 3D effect due to fortunate position.

That’s true – a postage stamp sized piece of fabric from that first aircraft.

Why observe the moon?

Ted Forte
 

As part of a virtual Earth Day celebration at Kartchner Caverns State Park in Benson, AZ, Rik Hill (formerly of Lunar and Planetary Lab, Catalina Sky Survey) has recorded a talk on lunar observing.  It is about a half hour  and worth watching:

 

https://www.lpl.arizona.edu/~rhill/TEMP/zoom_0.mp4

 

As Rik puts it, “the first 18 seconds are garbage” ( there are some  open mic preliminaries) but its professional after that!  Please watch.

 

The female voice is my friend and Rik’s wife, Dolores Hill, who is a meteorite specialist at the UArizona Lunar and Planetary Lab and ran the OSIRIS REx ambassador program.  She also chairs the “Target NEO’s” program for the Astronomical League and runs the “Target Asteroid Observing Campaign”.  Dolores  kindly bailed us out when the park’s virtual event coordinator kept dropping the ball on getting this talk recorded.  My thanks go out to both of them.  (Coordinating astronomy events at Kartchner is one of my many “hobby job” positions).

 

Rik will be repeating this talk for the Astronomical Society of Long Island next week.

Fw: The Long and short of observing last night

Subject: The Long and short of observing last night

You can't say Vixen does not go out on a limb to create something different.

Kent and I were able to actually plan and observe for an evening last night. The weather called for mostly clear, which it was mostly. The moon was starting to lighten the sky as a waxing crescent but not so bright as to be intrusive. Early on it did not look good as there were quite a few clouds but as the darkness decided they seem to relent a bit. Transparency was actually pretty good at 48% humidity. Saw a fair number of galaxies.

But to the point. Vixen has come out with another unusual eyepiece that at first blush defies rational thought. As a follow on to their excellent high powered eyepieces ranging from 3.4 to 1.6mm they must have been bored with high power. So what do you do? As some politicians say "when they go high; we go low" Vixen has taken them at their word and produced......................a 100mm eyepiece that is 1.25 inch in diameter. Why would you do that the mind asks? Well they claim it is a finder eyepiece that fits in the telescope. Oddly that is exactly what it is. It has a cross hairs and really does accurately convert a scope into what is almost a pone power finder. I bought this is a lark mostly as I do not need it but we did have a lot of fun last night with it attached to the 5 inch and the Orion 14.

Does it work? Well yes.

It has an eye relief measured in meters. Really, ask Kent. You can literally stand back and see a low powered view that is actually pretty good. Kent got back overt a foot! Considering how deep set is orbs are he may have achieved a fair bit over a foot. I could see M-3 in it and the cross hairs were dead on. For fun we projected the crescent moon on a sheet of paper from 2 to 2.5 feet away. Heck you could all gather round the eyepiece from 3 feet and all get a view. Think of the public viewing opportunities. Really. Now I want to try this in a dark sky and see if it is possible to get entire huge nebula in as it does accept filters.

One of the best things you can do if you have a larger reflector is you can create your own shadow transit on the moon. What is transiting is not important. You can create the perfect shadow transit anywhere on the moon you like if you stand off to the side a bit on the eyepiece; yes stand, I said that right. Interestingly the shadow of the secondary mirror really isn't that obvious down the center if you were using it as a finder. You can't fool physics but it does create a fun illusion. Maybe that's what the dinosaurs saw in the last microsecond before the asteroid hit, in the vacuum of the atmosphere...................... before.......................Emoji

Well really it is not too obvious surprisingly if using the eyepiece as intended. I thought this was a weird joke but actually I can see some use, especially for beginners and small scope users in manually finding a reference point. The eyepiece appears to be circumcised too if that is an added attraction. I have attached a picture showing the long and short of the Vixen range. 1.6 to 100mm.


2021 Boardwalk Astronomy Cancelled

Shawn Loescher
 

I received word today that the City of Virginia Beach has decided to not have Boardwalk Astronomy take place during 2021. Mike is hopeful that they will continue it up in 2022 instead. Having said that I want to give our club members a heads up that we will probably need to take extra club member donations again this year to help fund our scholarship funds for the upcoming school year since the money we receive for Boardwalk Astronomy is a major contributor to that fund. While I had hoped we would be able to have some of the Boardwalk events this year I encourage you to not get too discouraged though since I think we will make it through this difficult period fine.

Clear skies :)

It has been sunny all day here in Virginia Beach, but the Weather Channel, WAVY-TV10 weather, and the Clear Sky Chart are all predicting 90 cloud cover this evening and tonight.  I have been planning on going to Chippokes with at least one of my granddaughters, but I don't want to drive an hour to see clouds when I could see the same clouds at home.

I am still hoping the forecasts are wrong, so I'll make a decision in an hour or so.  It is 4:30 pm now.
