Check out this pic of the Orion Nebula I took.

Same lens and aperture but with ZWO ASI 1600mm-cool and a 7nm H-alpha filter.
20x120s guided exposures.
(had a bit of sensor tilt so the stars aren't great)

Handheld with a Canon EOS M + EF 100-400mmL II lens. I crouched down and used my car door for stability with my back against the side of the car. There was a slight amount of star trailing so I reduced it with Topaz Labs "Sharpen A.I."

I use better gear now but I was shocked to capture any color or detail in this manner with this camera.

very nice, what do you use for the guided exposures?

Here's my first astro photo. I took it recently on an old Contina viewfinder camera on Kodak ultramax 400. I think it was a 30 second exposure, untracked at 50mm. I was surprised how it turned out. I'd love to get a tracker someday and put on my SLR with a 300mm telephoto.

Thanks. I usually use my larger scopes but recently have been too busy to set them up and then break them down in the morning . So I've been using my portable rig that I can lift with one hand. I've been quite impressed with what I can get at 135mm even in my light polluted back garden.

Found this one that I took about 2 years ago with a Samyang 35mm F1.4 @F4 hooked up to my ZWO ASI1600mm-cool and shot using Baader H-alpha 7nm and Oiii 8.5nm filters combined in HOO.

The guided exposures are mine not the OP's (Is it possible to see which posts are from which users on here?)
For my widefield (up to 135mm, wide for deep sky astro) shots I use the Skywatcher Az GTi mount with equatorial mode firmware installed (plus a counterweight kit and equatorial wedge for easier polar alignment). I got this mount because I wanted to use my astro camera (currently mounted to the larger scope in the back) as well as my dslr with it so wanted goto capability for easy framing of targets. With my ZWO asiair (connected to the mount via wifi) I can guide with it using the small guidescope on top of the 3D printed mounting bracket for my Samyang 135mm F2.0.

Now, for staring out with longer exposure astrophotography you don't need everything I've got. You could start out with something like the Skywatcher star adventurer. That is a more simple and conventional star tracker. You need to find the targets yourself and then it will track (unguided) in right ascension. The star adventurer also has an auto guider port so you can add a guidescope and guide in right ascension with the aid of a laptop or small computer such as the asiair or stellarmate. For simple unguided tracking you can use an intervalometer to program a series of exposures.

no, but that's part of the charm.

thanks, I'll keep a note of that. It's no problem finding the targets myself, I think. I was considering building my own barn door tracker which would have been cool but maybe more hassle than it's worth.
