Astro log: Catching up, late 2010-May 2012

I've fairly diligently kept up keeping records of what I've been observing, either by tweeting about it or noting it in the notes on my iPhone or in SkySafari (also on my iPhone). It's been a pretty brutal last year and a half or so, weatherwise, so I had surprisingly few chances to even get out and observe anything. Plus, once you've fallen behind a bit it's hard to pick yourself up and get caught up.

Astro log: Sept. 23th, 2009

Equipment: Orion Skyview 6 Deluxe EQ, using the 32, 9, 6, and 4 mm eyepieces, and the 2x Barlow.

Previous objects observed: Neptune, Jupiter

Notes:

Didn't do much last night, but after I was able to resolve Uranus as a disk the other night I thought I'd give Neptune a shot again. I got up to 250x magnification with the 6mm and the 2x Barlow, and I'm pretty sure I saw a tiny disk. I spent some time comparing Neptune at that magnification with some nearby stars, and they were definitely more point-like, so I don't think it was a weird optics thing. So, tentatively I think I was able to resolve a disk from Neptune, albeit a very tiny one.

After I was done with Neptune I looked at Jupiter for a bit. It was its usual banded self, all four Galilean moons visible. Didn't spend much time on it.
