Stargazing Here's my latest M-51

    Still climbing the learning curve....

    Here's my latest M-51, nearly 4 hours worth of data, guided, lrgb. The skies were pretty inconsistent (making it noisier than it should be), so I'm actually pretty pleased with the result.

    When imaging, I accidentally slid my filters the wrong direction and ended up with two sets of reds - it took about 4 hours of mostly wasted processing time to figure that out. :grumpy: Tonight I had just enough transparency to redo the blue (it isn't great data, but it'll do). I'm still fiddling with the image, but this is about 95% complete. Note the dim, distant galaxy in the upper-right.

    Compare with my previous two tries at this galaxy...

    I just bought an Orion ED80 apochromatic refractor to use as a guidescope and for widefield imaging. I haven't taken many pictures of clusters with my new scope because the fov is too small, so I'll probably get a bunch in the next few weeks (they are easy - they don't take much exposure).

    Pretty nice, Russ. You'll probably have fun with that APO. I've got an 80mm f:5.6 Vernonscope APO that is pretty nice as a WF imager.

    Thanks. I've been updating it a lot lately.

    Here's a new pic of M63 I took a few days ago. Compare it to the previous one on my site...

    I still have a lot to learn, but it is fun being on the part of the learning curve where improvements from one image to the next are drastic.

    Very nice, considering the skies through which the light must pass.

    You need to get out west - like the Grand Canyon - where the skies clearer.

    Now this is what you could do if you had your own satellite.
