Telescope: Zhumell Z12 12″ Dob
Log: Observed with Tele Vue Ethos 13mm, 115x. It’s quite faint and diffuse. Very large. It’s got a fairly condensed core that’s medium brightness, and an extended faint haze. Visible are two or three spiral arms, one beginning at the center and moving basically straight up and then sweeping around to the right. Another beginning in the center, moving out to the left, then sweeping up and then over to the right. One beginning in the center, moving out to the right, and then sweeping down and to the left. There are quite a few stars suspended in front of the arms, faint ones, and the arms have a very mottled appearance. There’s a detatched patch of nebulosity to the right, and another one to the left, kind of at the ends of the spiral arms, probably H2 regions in the spiral arms. It’s a very pretty sight.
