Observing in bright moonlight

Kent Blackwell
 

Except for a very bright moon it was a beautiful night for stargazing with a gentle breeze and 60+ degrees. I decided to set up my 5” refractor and split double stars.

Double Double - Epsilon1 Lyr

(Double Star in Lyra)

Observed: Jul 22, 2021 at 9:07:53 PM

Comment: The famous "Double Double" looks fantastic using the 3.4mm Vixen HR eyepiece at 265x. Each of the four stars appear as small tiny dots with black space between them.

Mark Ost and I were both looking at this at the same time, yet we didn't know it. A very challenging pair. Both of us used the 2.4mm Vixen HR at 375x. It was easier in his scope, probably because he was using an equatorial mount and I an alt-az mount

Despite some clouds and haze about 500 people along the Virginia Beach Boardwalk stopped to look through our telescopes. I set up my small 80mm because kids have no problem reaching the eyepiece. It's nice to see several young new club members, especially Gabriel, who already has a passion and knowledge of observing deep sky objects.

Re: Willmann-Bell is Gone!

George Reynolds
 

Bruce,

I'm sorry to hear about your back problems.  We sure do miss seeing you.  If you plan to sell many of your books (I too have an extensive astronomy library), I'll bet there may be some prospective buyers in the club and on this chat group.

I was able to find a copy of Uranometria Vol 2 (Southern Hemisphere) from a third-party vendor for just $80, not too bad.  I received it a few days later, and now I have both volumes.  The newest edition was to have both hemispheres in one volume, but unless or until someone steps up to replace Willmann-Bell, it is not available.

George, BBAA members,

I have many William-Bell titles on my bookshelves. Almost all are like new, never fielded, and I cannot use any longer.
I may have the last Uranometria 2000.0 too. Need to look.

I can no longer field a scope much less a heavy mount since my last back operation.

Let me know what your after. I shall try to catalog my library this summer.

Of course I must say that this is completely insignificant compared to the great losses and personal tragedies of those affected by the fires.  Here’s hoping for the best, a quick end to the nightmare, and better times to come.

Another great star party cancelled for another year – the Oregon SP location has been declared unsafe because of the fires out there.

 

 

Too bad – even though too far to travel often (I’ll get there someday), I always look forward to seeing the results of Mel Bartels’ Telescope Walkabout.  Oregon has a lot of amateur telescope making activity, and the new scopes are exhibited every year at this SP.  Mel conducts this Walkabout to allow each telescope maker to present his work to those appreciative and interested, and discuss the features and innovations, what worked and what could be improved.  Here’s a Walkabout example – how about a 24” f/2.75 automated Newt that crawls around on caterpillar treads and auto-levels?

 

 

Lots of other Walkabout results online.

William,

It wasn't the pandemic.  It was essentially a husband & wife operation and they retired ... they're "up there" in age.  I frankly expected an announcement by now who'd pick-up their inventory and/or continue their titles.

Gary Cowardin, one of our Richmond Astronomical Society members passed away last year and his wife is selling his astronomy equipment to settle his estate.  Attached is a list of the equipment for sale.  Please pass along to your members.  If anyone is interested, they can contact me at president@... and I will put them in contact with Gary's wife.
 
Thanks for your help and best regards,

What a loss.  I didn't know.  I have purchased many books and from them.  I guess the Pandemic sunk them.

The Naval Observatory went down a couple of years ago, and data is scarce.  It seems like blind luck to find what I need.

What next?

“We are in the process of securing a new outlet for our books. Hopefully, in a few weeks that organization can make an announcement of availability.
