My best Andomeda Galaxy (M31). I couldn't get the entire galaxy in one frame. It's huge at 6 Moons in diameter (150,000 light years). These photons had been traveling across space for 2.54 million years.
Hardware: 80 ED APO 600mm refractor OTA with 0.85 field flattener on Atlas EQ-G equatorial tracking mount
Software: Starry Nights planetarium software, digiCam camera control, Autostakkert, Registax, Photoshop and Lightroom
Really very good. A keeper.
Thanks! The core is a little blown out (my exposures were a bit too long). But I can't darken the image any more without losing detail. But the best I could do with my existing equipment.

I don't have any equipment to do that. Piggyback photography with frequent guiding tweaks, all through just a camera lens, is all I have.
I don't know how many times you tried for that photo, but it's a fine effort.

With the equipment I have, I can do #piggyback, though I don't do it often. I've gotten lazy as I've aged. But some years ago, using 35mm film and piggybacking my camera on my telescope, I captured a nice image of #HaleBopp comet.
Love this! So many of my photos are on film. I have a photo of the Orion Nebula that you could easily get with a 400mm lens. Nothing wrong with going camera body with telephoto lens on top of a tracking scope or device. Just make sure that the device and camera lens are both aligned to the same point. You can do that in the daytime with a distant object then you're set for long tracking exposures. Plus the 
glass is usually far superior to a 
due to wider aperture (e.g. f/4).
