Object name: STOCK12

Designation(s): STOCK12,

Stock 12 is an open cluster in Cassiopeia. Webda puts it at 1300 light-years and shows an age of just under 300 million years. It has virtually no reddening other than my smoke may have added. The cluster is classed as IV 2 p. The smoke was nearly gone for this one so the colors were easy to adjust after far too many that were so damaged I have no idea how accurate the color is. This one stands out strongly after weeks of images so low in contrast thanks to the thick smoke. There\'s little on this cluster. Only one galaxy has redshift data. It is to the upper left of the center of the image and the brightest galaxy in the image it is 2MASX J23362696+5242419 at 480 million light-years. I didn\'t prepere an annotated image for this one galaxy. Many others are visible thanks to little smoke for a change but they have no data at NED other than position. Most don\'t even have a magnitude.

I am following in the footsteps of Dan Crowson who took it over a year ago. Except for his much lower resolution image I\'ve not seen it posted here before. I picked a previously imaged cluster because I was after something simple to process after weeks of super nasty smoke. For that it worked nicely.
