I said yesterday that I would be taking a break for a few weeks, but first I wanted to share two more things. First, the majestic waning gibbous Moon, just past full, close to setting this morning:

Frost on trees, 7:52 AM, February 6, 2012

I need to take a break from blogging for a few weeks to get some important stuff done, so here are a few more astrophotos for you in the meantime. See you in March! (Feel free to leave comments, I’ll try to respond as I’m able.)

4:20 PM CST 1-28-12 (22:20 UT), 25mm eyepiece

11:25 PM CST 2-1-12 (5:25 UT 2-2-12), with my old 18mm eyepiece, which as you can see has some cloudy patches due to damage, but I keep it in the shed with the telescope so I always can use the telescope in a pinch even if I don’t have my other eyepieces with me.

12:59 AM CST 2-6-12 (6:59 UT), 25mm eyepiece

11:36 PM CST 2-7-12 (5:36 UT 2-8-12), 25mm eyepiece

Mars at 7:38 AM CST 1-28-12 (13:38 UT), 25mm eyepiece with 2x Barlow.

All with 8″ reflector telescope and LG VX8360 cell phone camera. Click for larger view, except the Mars photo won’t get any bigger.
