[Attachment(s) from Jim Tallman included below]

Well finally had a night where sky was clear, I was home, and it wasn’t a work night! Since the dreaded Daylight Savings Time began, it really pushes back the start time for viewing one must get up early to do much imaging, that is where work gets in the way. But what the heck, it pays for all of the toys I haven’t been able to play with yet.

 

Yesterday afternoon I set up the G11 and the Takahashi to test out the new CCD camera I acquired a couple months ago and then got back up at 2AM to go play in the yard. Last Feb. I purchased an open box ZWO ASI174MC CCD camera with cooling.  It took me a while to figure out how to get the exposure correct as it is way different from the DSLR setup.

 

The cooling feature on the CCD is really nice. The camera was at 61F when I turned on the cooler and it quickly got down to 26F and stayed there. APT works well with DLSR camera and seems to do very well with CCD cameras also. I really like the auto focusing feature it has built in as well as the plate solve capabilities, it makes getting the target object centered automatically. If you are not familiar with Astrophotography Tool (APT) it is a very nice application for setting up you imaging sessions, and only cost about 15 Euros to buy, and 6 Euros annually.

 

Anyways, once I figured out how to get the exposure correct and the imaging run set up, I started with something easy, M57.

2018 T-shirt order

Shawn Loescher
 


This year in preparation for our upcoming summer events I want to order "wicking" t-shirts. These shirts are designed to wick moisture away from your skin and they should not fade as easily as what we got last year. Another benefit is that they are $17 instead of the $21 per shirt we spent last year. I have attached a couple of pictures of the design we are looking at doing which is the same as we did last time. The company we are using (Cavalier Sportwear) has many colors available with sizes ranging from S-3XL. If you are interested in getting one please go to the "Purchase BBAA Apparel" section on our store page (http://backbayastro.org/store.php) where you can pick out the color, size, and pay using PayPal. When we have enough to order 10 shirts I will contact Cavalier Sportwear about submitting the order.

Features:
100% polyester jersey knit
heat transfer label
Aqua FX ® for wicking properties
Freshcare ® for anti-microbial properties
double-needle hemmed 5/8" sleeves and bottom hem
rib knit 3/4" collar (no topstitch)
snag resistant

If you have any questions let me know.



Thoughts on a night's observing

jimcoble2000
 

Thoughts on observing late into the night.

Baby it's cold out there. After two nights of deeper observing I had some thoughts. I must admit the views within our galaxy, represented by the summer, fall, winter line up, are much warmer and aesthetically pleasant. In a strange way like siting at home around a known fire. Spring galaxy observing is a much colder and remote occupation, an astronomy of the mind as much as visual observation. Few stars; deep darkness, and cold space pretty much sum up the pursuit of of these objects. I enjoy both types of observing but find, as I get older, the dark streaks of light, seen at this time, remind me more of impermanence offering cold comfort in contrast to the fine star fields of our home.

Of course this makes no rational sense, the distances being vast either way and our life so ephemeral in contrast to all these objects but I can't help but feel there is a difference after spending a late night until 1:00 in the morning straining my eyes for the slightest glimmer of light in the darkness. Still it was a good night and there is some value in knowing and seeing, while you can, what there is; as compared to the vast population of this planet that has seen nothing of this. For the vast majority of people these sights are known only dimly, abstractly, or never in a lifetime seen at all. Ever.

Orion or Souther SKies WiFi control module

charles jagow
 

Does anyone have either a WORKING StarSeek (Orion) or a WORKING SKYFi 2 (Southern Skies) the model that has an RJ connector and a USB connector on them that they would be willing to sell?

I am looking for one of these older units as they are powered by either battery or external 12VDC. 

The newest model is lithium battery only, and is rechargeable by USB micro connection (5VDC).

If you have one that is working (I don't need any cables) just the module, I would like to buy it, and then you could perhaps upgrade to a newer one?

Let me know if you are interested.

Re: Jupiter Imaging Impact Project

Benito Loyola
 

George,


Been getting real good data of Jupiter.  Even when close to the moon, and hazy like last night still got 2 hours worth of decent images.


So lets get you started if you have not done so.  The magic starts in getting the focal length of your set up to match up with the camera pixel size to get Jupiter across at least 120 pixels.   In nearly every case, between a 1.5 - 3x Barlow will get you there with most telescopes.  The one you use can be calculated by:


Barlow Magnification = 825 * camera pixel size in microns / telescope focal length.


Just insert the Barlow on your telescope, then the camera into the Barlow.


For the capture session, get your telescope out for at least 30 minutes to get it equalized with the outside temperature.


Using a regular eyepiece if that is easier and get a decent 2-star or polar alignment depending on your mount.


Your Orion camera comes with driver and capture software.  Would follow ReadMe instructions and install both.  One you connect the camera via USB and run the software you should be able to connect to the camera.


With your software running, adjust the exposure and gain to see stars by adjusting the focus.  Then move to a bright star near Jupiter. There take your time to get your focus as best you can then move the scope to Jupiter.  Due to atmospherics Jupiter will still look a bit out of focus but if you got a good star focus you will be fine.


Your alignment will drift over time, not to worry, just use your manual or electronic controller to keep it centered as best you can.  An occasional move will not hurt your data capturing several frames per second.


Adjust the gain and exposure time as to not saturate Jupiter.  Should be bright enough to see the bands especially when it captures an occasional good still (not so disturbed by atmospherics) image.


Your camera should save the images as an AVI or SER video file or sequentially numbered JPG images.  Run a short capture then go to your default folder and check to make sure all is working.  If all looks good, run the capture for as long as you can.  You can break it up in to blocks of several minutes.


I was imaging through thin clouds, haze and near the moon and there was plenty of good data captured.  The impact detection software is much more forgiving than regular astrophotography.


Once you have the data, you will upload it to the folder Kunio Sayanagi has created and can run the DeTeCt software locally and forward the report.  


There are plenty of YouTube videos out there that will walk you through all of this in more detail depending on the camera and mount you have.


You are always welcome to call me anytime to discuss.  Wish you good skies.
