M105 etc, M51, M82 and Backyard Setup-Reposted


Kepler 3

Recommended Posts

Hi,

My backyard has really bad light pollution, but I've wanted to be able to do observing without having to, at my age, drive out of town and set up-so I set things up in my back yard. I have a 6" C6 SCT with f/6.4 reducer, an Orion Atlas mount, and an Atik Infinity monochrome camera. I set it up outside of my office area and decided to give it a try. I used SharpCap Pro to get my polar alignment done accurately and a 3-point star alignment-all of which I hooked up to my computer with USB cables(you can see my office setup in attached photo). I mainly used my iphone StarSeek app to operate my scope. I had a great time last night-I was comfortable and even was able to brew some a cup of tea while one of my images was stacking-what luxury. I captured M105/NGC3384/NGC3389 20s exposures x 20 stacks, M51 25s x 13, and M82 20s x 22. I also observed other fainter objects in Leo with less success-very washed out. I have ordered a UHC filter and will try to block out more of the light pollution (my yard borders on a public park with a bright sodium street light 50' away). I just wanted to share this-I think it's going to work. I plan on doing some spectroscopy with an Alpy 600, so hopefully, the light pollution won't be such a problem.

Thanks

Dick

They're impressive results especially given the light pollution. I also like the FOV you're getting with that scope/reducer/sensor combination. 

That looks like a nice comfortable setup. Whenever I can I try to find a way to trail the cables so I can setup just inside the door, although there's always a bit of draught... Anything to stave off the cold and lengthen the observing session!
