I'm going to use this topic to post various deep space objects that I'm photographing from my backyard. Most of them are open clusters since they are the most easy to capture in heavy light pollution. All images are taken through a 10'' dobsonian and ZWO ASI120MC camera. I had luck with two evening with very good seeing so I stayed several hours in the cold to capture what I'm gonna present in this post.
1. Mu Cephei
One of the largest known star, surrounded by several small companions. The image is obtained after stacking 50 frames with 500ms exposure.
2. M40 - Winnecke 4
Nothing too special, just a nice double star. 10 frames x 500ms exposure.
3. M81 - Bode's Galaxy
Far from the best one you'll see but from heavy light pollution area and static mount is probably the best I can obtain. 650 frames x 1s exposure. I also wanted to capture the Cigar Galaxy but there was no sign of it.
4. NGC2169 - The '37' Cluster
A nice colorful cluster just above Orion. 300 frames x 250ms exposure.
5. NGC188 - Polarissima Cluster
Surprisingly crowded cluster, pretty hard to see 'live' but due to being close to the North Celestial Pole I was able to use 2s exposure without star trailing and captured many stars. The resulting image is a mosaic as the cluster is too large to fit on the camera's sensor. I captured separate areas from the cluster and loaded all the frames in DeepSkyStacker. Surprisingly it was able to do the mosaic automatically. Pretty amazing what the little program can do! Total frames used for the cluster: 420 x 2s exposure
This is my favorite cluster so far. The process of capturing is the same as NGC188. For this one I used 4560 frames x 350ms exposure.
