Looks like I need to take a better picture if you think this is a CW keyer.

Nope. Hint
it is an antique part of astronomy history

CW keyer was my first thought too. The second thought was "he needs a better picture"

Hey I'm a beginner! What did you expect?

A CW keyer is probably a better guess than a ETX125 in a box with a speaker.

Now why would anyone put up a picture of a CW keyer under classic telescopes?

Tonight I will post a better picture. Sorry for the confusion. I will give a hint that it is part of an assembly. Maybe no one else has ever had one of these apart. I was surprised to find this beautiful laquered box.

It's a very beautiful focal plaine curtain shutter. It was used on older large format cameras and also on astro cameras.
See the Polarex/Unitron cameras

My, we have a bunch of hams here, huh? I'm K4CMD!

Funny, I got into ham radio because a (now-deceased) member of our local astronomy club was a ham. He used to bring mobile rigs out to observing sessions in the late 70s (when mobile rigs looked like today's base rigs, lol). The bug bit me hard and he actually administered my novice license exam to me in 1979. Here's to ya, Jean-Paul!

73 to whom it concerns above, and yes, my initial thought was also CW key/keyer of some sort, but I kept my mouth shut because of the subject of the thread ...

Very good. I knew a Unitron collector would figure this out.
I will take a picture of the whole camera. The one I have is on of the nicest ones I have seen. I am sctually thinking of cutting up some 120 film and trying it out. from what I have gathered even the best digital camera is still nowhere close to the pixel count of film. Film is around 380 mega pixels.
