Argh! This is a terrible terrible picture! Exposure is suboptimal for this kind of target, focusing is also subpar, and the processing... Oh well, I know that even then I could do better so I guess I was tired that night or something. This is IMHO probably the worst picture I've published here in my site so far. It's here because it's the only one I've done at this target, but eventually I think I'll just remove it because there really isn't much to see here.

Here's a mosaic of three images take with my C11 from my backyard. The focus is terrible for three reasons: 1) The seeing was terrible from my backyard. 2) The native focuser of the C11 really doesn't help - and that moving mirror didn't help either!. 3) In addition to 1 and 2, I didn't do a good job.

At a smaller scale, that's not apparent, but if you see the original image you'll see what I mean.
