You've heard of the Andromeda Galaxy and the Orion Nebula, but how about the Orion Galaxy? Probably not. But would you believe the New General Catalog lists 21 galaxies in Orion, and the Index Catalog adds another 9? That's a pretty respectable tally. Of those 30 Orion galaxies, I find this month's challenge particularly intriguing because it lies so close to everyone's favorite winter deep-sky object, M42. Yet, I am sure that very few observers have seen it.

Thank you, Phil. I never think to scan over that way.

Hey, that's a great article Phil. Definitely enough there to get me out on a clear cold night to try and do an Orion galaxy sweep. Just like trading cards when I was a kid...I want to collect 'em all. As always, most of your observing reports are unusual in the sense that they cover many things I've never seen before and I do appreciate that. Thanks!

Though I have your book, I've never went for this one.  If these lake effect clouds go away when the moon's not up, I'll give it a try with my 7" reflector.

There's an image of NGC 1924 posted at http://www.kopernik....chive/n1924.htm

Thanx, Phil; I'll haul that list out to the scopes. Nice and convenient all in that one piece of sky. Galaxies are all over the place, even where we generally don't think of looking for them.  Tom

I wasn't crazy!!!

Last year while scanning Orion at a dark site, I noticed a smudge there .. I had to use averted vision, but there was something ... I mentioned that to some fellow guys, they gave me the "you just got crazy" eye...

NOW I know what I was looking at.


From now, on, I can re-see that object (NGC1924) with total confidence ...

I shared the article with another CN member and we are going to have a ball at out next star party in a Bortle 3 sky. I have already found NGC 1924 with my 8SE and I will be using my CPC 1100 at the star party along with a AT 130EDT refractor.... This is going to be nice

Yep, looking at "that thing in Orion, at its west side" showed me my (averted and technique) vision has improved a lot since I started with my first telescope :)

Enjoy the SP!!!

I m signing up for RTMC in May, like Woodstock ... but with telescopes :lol:

I took  a single  8 minute exposure of ngc  1924 with my 10" lx200 classic, and you guys have a lot better eyes then I do.  What a faint target!   You have my respect.

Thanks for the heads up an NGC1924. I'd never seen it before. 


While i was looking at Sky Safari to locate 1924, I noticed a small group of galaxies about 5 degrees at 300 degrees from 1924, PGC 16893, PGC16895 and UGC102. They're listed at magnitude 14.5-14.8. My skies aren't the darkest to the south,  there's a prison across the border in Mexico but i was able see them in the 22 inch. 


Now you've got me interested, I'll be looking for more..

There was a hole in the clouds in upstate NY last night, so I gave the challenge a try with my 8"reflector. I was unsuccessful, but sure enjoyed the effort! I'll keep trying, and when I get another hole in the clouds I may try to filter some of the sky glow to see if that helps.
