On the evening of November 6th, 2013, I was able to get out for a bit of observing. Not long as it was a work night but I wanted to take advantage of the fact that a young crescent moon was disappearing at 8:30p.m. and would let me have several hours to accomplish my goals of sketching for the night.
I set up easily enough and did some lunar observing, and then some double star observing as I waited for the moon to set. I also looked at some eye candy (Messier) objects in the summer triangle one last time, a good-bye to summer. M13 again, M17, M11, M57 etc.
Well, I started the evening as the moon was gone up in M31, the Andromeda galaxy. I used the article out of Sky & Telescope's November issue on Exploring Andromeda by Alan Whitman, to do just that, explore Andromeda. I made what I think is a find sketch of M31, and a sketch of some of the globular and open clusters, including NGC 206. However, as you will see in a moment, I am having trouble with my camera taking pictures tonight so those sketches will have to wait until I can resolve.
I am going to post my other two explorations.
1. NGC 7635, Sharpless 162 or The Bubble Nebula. Constellation: Cassiopeia; Date: November 6th, 2013; Time: 10:07p.m. MDT or 04:07 UT; West Desert, Utah; Antoniadi III; Equipment: 14" Dob with 14mm, 10mm &7mm Pentax XW; OIII and Ultrablock Filter.
Notes: The Bubble is at its brightest near the mag. 8.4 star near to it. To the NE there appears to be some dark lanes evident, north of the nebulosity also. There is fainter nebulosity to the north side of the lane. Main part of the Bubble hooks around the mag. 8.4 star, SAO 20575. The Wolf Rayet Star is causing the brightening here as it heats up the Bubble with its stellar winds. The sketch here is fine, I like it in person a lot but I am not happy with the image so I intend to re-shoot it and replace this one.
2. Cassiopeia-A, Supernova Remnant in Cassiopeia. Constellation: Cassiopeia; Date: November 6th, 2013; Time: 11:21p.m. MDT or 05:21 UT; Location: West Desert, Utah; SQM: 21.71; Conditions: Clear, cool, Antoniadi III; Equipment: 14" Dob, Zambuto Mirror; 20mm & 14mm Pentax XW; 17.3 Delos; 27mm Pantoptic; OIII Filter.
Notes. What got me going on this was Sue French's Deep Sky Wonders article in December where she discusses going after this object. In addition I know there are several threads over on Cloudy Nights about amateurs observing this object. So tonight, I took my turn. Sure enough using the finder charts I got off of Cloudy Nights I was able to see this supernova remnant. It is not a hard object to find, if you have the finder charts for it. There is a triangle pointing to the bright remnant and it is basically a broadening band with knots of brightening at both ends. More of a straight line in between with some mottling. I hinted at a possible branch below it with averted vision. The OIII filter helped the most.
