Very nice Sterling! I always like to see the gap between the mane and the head which is hard to get, and you got that!

This is only 32 minutes of data, or 64 shots at 30 seconds. ISO 3200. I’m pleased with how this turned out. Less noise than my Pleiades shot. Maybe better processing.

Very nice Sterling, where did you take the pictures? CMO?

Very good, Sterling, especially for such a short total exposure time!

Nexstar 5SE

John
 

I have a very nice Nexstar 5SE up next on my chopping block.  I do not have the tripod and am willing to part out as follows:

Optical Tube: $300
Mount: $250

If you buy them both, I'll take $500 total meet up for delivery in Birmingham area.  

These sell fast on Astromart and CN, and New ones are $699 plus tax and shipping.  So if you want it, act fast.  I will give priority to someone who says they want the whole setup.

Thanks,
John


LX80 Multi-Mount For Sale

John
 

I paid $900 new for this most infamous of all Meade mounts.  Mine has always worked perfectly, though, unlike the horror stories I've read from others.  I only used it visually and only in Alt-Az mode.  It has carried a C9.25 and 8" Newtonian together many times, as seen from the attached photo at Chandler Mountain.  You may have seen it there a few years ago.  I have the box and all paperwork and accessories.  I would like $500 delivered in the Birmingham area.  You won't find another mount that can do what this one does, that is for sure.

I agree.

I have been a member for many years and visited often when I lived in GA, but have not gone recently. I prefer it to French Camp and it is about the same distance. I hope to visit more after my new equipment arrives.

Re: Deerlick Astronomy Village

Many members know the Deerlick Astronomy Village in Georgia as the site of the annual PeachState Stargaze.  I recently purchased a field membership at Deerlick so I could join friends from the Atlanta area for observing and imaging.  An annual membership costs only $35 with an additional charge of $5 a night for camping—quite a bargain.  The observing field has many concrete pads plus ample power outlets.  Wi-fi is also available and there is a covered shelter with picnic tables plus three bathrooms with showers.  The only disadvantage is the drive time of 4-and-a-half to 5 hours, depending on Atlanta traffic.  The village is located in Taliaferro County [pronounced tol-i-fer] with a population of about 1800 and dropping.  This is a good location for anyone who can find a few days to pack up and go.  Given the distance, I have only used the site when the weather forecast justifies the trip.  The nearest sizable town is Washington, GA about a twenty-five minute drive where there are a few restaurants and supermarkets.  If something breaks [may God forbid!] a Home Depot is about 45 minutes away in Greensboro, GA.

The following link provides information on Deerlick in case any members are interested.



All the best and clear skies!

Beautiful shot, Sterling. Would you mind me sharing this on our BAS Facebook page? With the proper attributions, of course.

Nice! Interesting background color gradient makes it very pretty.

This is about 1 hour of data and 24 darks, but only 20 second shots a piece.
3200 ISO. I need to do flats though as well.

I very much enjoyed last night's presentation. (had to rush off early). Thanks all.

Something we could do with a remote meeting that would have been difficult otherwise (COVID silver lining).

Re: November 2020 Monthly meeting

Robert Pitt
 

Sounds familiar Don. I have been using NGC 7243 to work on my collimation as it is in a good position and fills my frame nicely. Almost there, but just a few tweaks tonight on the tilt of the primary mirror to deal with some minor coma in one corner remaining (and hopefully I won’t make it worse). Then go over polar alignment again, and finally model the mount with about 30 stars. If I’m lucky, I might get M42 and vicinity early morning, otherwise tomorrow and thurs (better seeing then projected anyways). I might try to make the call from my observatory as I fiddle (will be a bit chilly with the breeze so keep warm!). The GEM45 sounds like a great mount, let us know how it works out. One advantage of mirrorless cameras is not having to black out the camera eyecup!

Regards,

Bob

I might not make it with the clear skies tonight. I've been working with my new Hyperstar in my driveway and making good progress. I am using NGC7331 as a target as it is fairly bright and well-positioned. I have been experimenting with different gain/exposure for the ASI290, and I think I have found the range at around 15 secs. Maybe if I get set up and let the camera run, I can join for at least part of the meeting. Using my driveway, I can "hibernate" this old CG-5 mount and so it is (usually) still aligned. I find this does not always work and sometimes the mount gets confused, but it's ok - it only takes 10 minutes or so to align and add some calibration stars. I have ordered an iOptron GEM45 for a step up. One interesting thing, is the Hyperstar seems to allow light entering the eyepiece to be recorded, so I have to cover the eyepiece.

Stay safe. As you know, this virus is gaining ground. Would not be surprised if Alabama gets much worse and possibly shutdowns.
