Hello Astro-Nuts, In recent weeks a few forum members have mentioned it would be nice to have a repository of old AP catalogs and offered to create a website database. This is a project we’ve had on our radar but have not had time to dig into, so we appreciate this has been taken on by some of our Astro-Nuts. The website is here if you’d like to take a look: AP Product Catalog Database While you’re there, check out Tony Simon’s (aka Harley Davidson and Star Astronomer on YouTube) video of his catalog collection. If you have old catalogs and would like to add them, you can upload them to the Files section of the ap-ug group or the ap-gto group on Groups.io. They will be added to the database from there. I’ll pin this topic on the Groups Messages page so it’s easy to find. Many thanks to Holger Merlitz for creating the website and volunteering to steer this project, and all of you who have submitted your catalogs to the database. And a challenge: Can anyone find a catalog with the Hampden Ct address? Karen AP

Small, bright NGC40 5 messages
Lately it seems like the only clear nights I get are around the full moon, so I've been shooting a lot of narrowband over the last two or three months. First up is NGC40 in Ha and OIII, with RGB added

This is a corner crop from subs I shot when centered on NGC7331, so a bit of a freebie. Best viewed at full resolution, these guys are tiny. Shot with my 12" Newt, ASI2600MM and AP 1100GTO. https://ww

AP92 f/6.65 without flattener 2 messages
Just for fun, I tried shooting my Stowaway without a flattener to see how the field curvature would be with a 24x36mm (35mm full frame) sensor. For postcard "web" viewing, the curvature was much lower

NGC6888 The Crescent Nebula - 6.3 hours OSC 6 messages
Imaged the Crescent over 3 nights with an Optolong L-eXtreme Dual-band Filter. Had to throw away a good number of subs due to the moon. The moon was a factor since this filter only has 7nm skirts on H

The Lobster and the Pearl 7 messages
I saw a nice image of the lobster claw nebula the other day and hadn't seen it before, so I made it my next target. I used SGP's framing wizard to compose the shot, I noticed this other nearby nebula.

NGC7822, Sharpless171, LBN583 (Cep) - Hot Stars with Cosmic Pillars of Dust / OSC 3.3 hours 11 messages
There's a whole lot of action going on here looking at the plate solve. Some real hot stars. I shot this in between galaxy hunting with the 155. The moon was up so I made a run of 55 images from dusk
