Open Cluster IC 4756 w/ IR data

Posted By Jim Thommes
Here is an image of the open cluster IC 4756. I took the LRGB data June 22. The IR data is from the Wide-field Infrared Survey Explorer. This is one of several I have done over the summer so far.

It is interesting to see our galaxy's background IR data and some of the really significant IR emitters that have little or no visible band emissions.

NGC 6811 and NGC 6819

Posted By Jim Thommes
Here are two well known open clusters in Cygnus. The Hole-in-a-Cluster NGC 6811 and the Foxhead NGC 6819. I can see the hole in NGC 6811, but I have never really seen the Foxhead.

Two Clusters M52 and M23

Posted By Jim Thommes
Here are images of M52 and M23. I struggled with some clouds and retook some data under a first quarter moon on M23. M52 mostly survived the clouds. I also used some earlier data on M52 that was more of a close up - it helped to resolve the stars better. This is a technique Rob Gendler has used in the past. Images and details are here:

LBN 234 in the Gamma Cyg Region

Posted By Jim Thommes
Hi all,
This is an image of region just south of Sadr (Gamma Cygni). I have both the H-Alpha image and a blended RGB H-Alpha image:

Central America

Posted By Jim Thommes
Many of you will recognize this image as the Central America portion of the North American Nebula, NGC 7000. It is kind of interesting to take a familiar object (or a part of it), offer a *different* orientation, and then it seems like something else. I think it looks like a Bat:

A more conventional orientation and details are here:

There is also a H-Alpha image here:

More Cygnus Images

Posted By Jim Thommes
I have done a couple of out of the way images in the large emission region in Cygnus. This region is dominated by the large LBN 310, but there are several other smaller LDN and LBN structures in this field. Image and details are here:

NGC 6866

Posted By Jim Thommes
Here is NGC 6866 - a nice open cluster in Cygnus that gets overshadowed by its more famous brothers. Image and details are here:

LDN 1251

Posted By Jim Thommes
Here is an image of LDN 1251. Its processed a bit heavy to show the dark regions. This is considered a star forming region. I may check out a few more dusty regions this fall / winter. Anyway, image and details are here:

LDN 1295 and 1296

Posted By Jim Thommes
Here is an image of LDN 1295 and LDN 1296. The data was only a little over 3 hours, but the processing came out reasonable enough to show the objects. So I thought I would post it. Image and details are at:
