I was out a couple of nights ago, mainly to test out my in-door setup for taking pictures, after acquiring cables for powering the DSLR, data transfer from DSLR to PC, and telescope control. It works out great, only nickle I have with it is the focusing aspect, as I have to run in and out to check it. Need to figure that out.
But oh well, I figured that I'd try shooting one of my favorite galaxies, the "Black Eye Galaxy". It's been one of my favorite ever since I saw the hubble photo of it, making it literally look like a "corrupt" galaxy. I had several issues, both with focusing, proper balancing of the mount, dew on the secondary mirror and accidentally deleting my alignment, so out of the over 100 pictures that I took, I only ended up using 30 of them for this picture (Seriously how many satellites pass through that area of the sky?!). But I was pleasantly surprised to see, that I could pull as much out of it as I could!
I need to figure out, how I can train my mount for PEC with my DSLR too, before I have to throw more money into gear, letting me guide.
