So new I don’t even know what I’m doing. But here are two I took last night (they were “the best” of the bunch). Orion Nebula and the moon. Using my 90mm, 910mm, f/10.1 scope with a Panasonic LUMIX GH3. Prime focus method. I believe the nebula was 30s exposure, ISO 400. Might be wrong tho. No filters

The photo of the Moon is nice. As for deep sky objects, you have to take several photos and stack them to get better results.

Quite exciting for a simplistic setup. The 30 second shot is showing the beginnings of trailing stars. Were you using a motorized mount? For exposures in long focal lengths you only have a few to maybe 15 seconds before trailing becomes noticeable. Long exposure deepsky reality needs motorized tracking and for advanced imaging autoguiding is the thing. With a EQ mount and good polar alignment you should be able to image well for a minute or two.

Looks like you had fun though.

Yea I have seen a lot about stacking but haven’t looked into the methods behind it. I shall one day!

It was on a Celestron ASGT CG-5 mount but admittedly, my polar alignment wasn’t the best. It was doing some wacky things last night haha. Usually I would do 2 alignment stars, 4 calibration stars, all star polar alignment, and just started doing precise Go-to. Something was weird last night tho so that’s why it was trailing. As I gain experience I will definitely look into a auto guider as well. Thanks for the input y’all!
