NGC 869 and 884 (Double Cluster) sketch
Posted 18 November 2009 - 11:18 PM
I was using a Zhumell Z12 12" F/5 Dob with a 17mm Hyperion EP (0.8 deg. FOV at 88x). Naturally, I couldn't fit the entire Double Cluster into one FOV, so I sketched them separately and stitched them together using Paint .NET. In my pencil sketch, I had added some shading at the center of each cluster to give it that dense star field look, but it was too light for the scanner to pick up, so I added it back in in the processing.
Well, anyway, here it is (NGC 884 on the left and NGC 869 on the right)
Here is the original unmodified pencil sketch. I lightly circled one star in both sketches knowing that they were the same star, so that when I merged the two, I used that star as the merge point. Then, I eliminated duplicate stars that were in slightly different positions due to sketching errors.
Thank you, and I hope you like 'em.

Nicely done. You've captured this wonderful object nicely.

This is a beautiful sketch of the double cluster.

An excellent observation of the Double Cluster in Perseus. You have captured this impressive cluster nicely. Thank you for sharing it with us all.

I like to include the unmodified sketch when I can. It makes an interesting before and after comparison. But, sometimes the scanner does a poor job of scanning in the image, and so I have to clean it up somewhat.
