I was out Sunday night (11/15) into Monday morning (11/16) and was attempting to sketch the Double Cluster. I started around 10:30pm and by 1:30am and I had only finished NGC 869! I packed it in. The other half, NGC 884, would have to wait. I got my chance to finish the sketch on Tuesday night (11/17) into Wednesday morning (11/18) and I was just about finished with NGC 884 when clouds came in and ended the session. NGC 884 came out a little bit sparse as a result. 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. -Slartibartfast Post Extras:       JayinUT I'm not Sleepy Reged: 09/19/08 Re: NGC 869 and 884 (Double Cluster) sketch [Re: Slartibartfast]       #3456174 - 11/19/09 12:20 AM Edit   Reply   Quote Quick Reply   Slart, Nicely done.

You have captured this impressive cluster nicely. Thank you for sharing it with us all.

Interesting the way you merged the two sketches into one.

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.

Open clusters are challenging objects to me, moreso than even galaxies. It requires a lot of patience and attention to relationships between stars to render these fine objects well, and you've done a great job. I instantly recognize this duo from your sketch. - Jay South Florida Post Extras:       DC869 journeyman Reged: 10/16/09 Loc: Midwest, USA Re: NGC 869 and 884 (Double Cluster) sketch [Re: JayKSC]       #3461497 - 11/21/09 11:07 PM Edit   Reply   Quote Quick Reply   Nice work. It's still one of my favorite targets, and you captured it well.
