I had not done M105 previously, so here is my first try at it - also round two with the 10" f6.3. I did get some Bob's knobs, but think I need a second collimation try, as that 6.3 seems trickier than the f10. I thought my flats were much better when I took them, but I ended up with a weird blue streak coming from the side. (Any ideas?!)
As long as all possible observing issues are converging in the Four Corners this month, I was not surprised when I got ice crystals in the camera that I hadn't seen this year yet. Today I am baking the desiccant, but that won't help the higher temperature on this set of shots. Or maybe these things are just dim. LRGB was ~32:14:14:16 total via 2 min subs.
...and finally when I tried to post, I get the message that the file is too big, so I reduce the jpg quality... probably those leftover color dots... arrggh...
Comments and critiques always welcome.
