M31 – The Andromeda Galaxy – 3 Panel Mosaic

Haven’t really been able to post in awhile, been working on other projects that are taking up way too much time. Finally got two nights over Labor day weekend. Figured I’d do M31 since its been a long time since I’ve attempted it. I’m imaging at 800mm with a Canon T3 so I had to do three panels to get it all to fit and even then the wispy bits on the edges are cut off. Lots of nasty gradients to deal with on account of lots of high altitude haze. This summer in Socal has been too humid. Only got about two hours per frame over two nights because of the clouds. Processed in Pixinsight and Photoshop.

NGC2170

Took several days off last weekend and this was my primary goal. What a difficult target! 9 hours is not nearly enough, not to mention I was using my unmodded camera (modded cam needs a new sensor). But I don’t think I’ll get a chance to get more time on this object anytime soon so here is this one for now.

M45, the Pleiades from Tierra Del Sol

Got to spend four wonderful nights at my clubs dark site over Thanksgiving break. My main target was NGC2710 but I had to shoot something each night while waiting for the target to rise so why not go for M45 (its been awhile!).

This was shot over four nights and I changed the angle at some point which explains the odd diffraction spikes.

M31 Andromeda Galaxy Mosaic

This one was very very tough. I had some very bad gradients from light pollution, upper atmosphere clouds and a red LED that somehow leaked light into the scope causing some nasty images in the core frame. I’m not sure if I’m happy with the colors or not so I may come back to this one shortly.
