Last night wasn't the greatest, but I had a chance to observe for a little bit with my AT72ED and binoviewer. There are a few subtle changes in this sketch from my previous ones. First, the can of tuna stayed in the kitchen pantry. Instead, I used an oblate template I made from a scrap piece of Lexan, not quite 7%, but it will do. Another subtle change are the colors. They're there, just extremely light, as I saw them through my small refractor. The overall light areas are off white, and there is a very subtle limb shading. The North Polar Region came out a bit too yellow, as well as the NEB turning out a bit too ruddy and pronounced. Otherwise, I'm pretty happy with it.
My planetary observing has improved since I started last year. I find that I'm observing subtle colors I didn't see before, as well as observing many details and features, although too often I haven't a clue what I'm looking at. Hey, I'm slowly learning, like my recent 'discovery' of the Oval BA.
EDIT: On the sketch I noted Celestron Plossls. They are actually Astro-Tech plossls. The difference is the AT 15mm Plossls have a field stop, which, according to reviews I read, the Celestron 15mm Plossls do not.
