Veil Nebula HaRGB (NGC 6992)Posted By Enrico Africa |
Here is an H-alpha/RGB of the Veil Nebula (NGC 6992). The data for this was taken over two or three weeks last August, and after several long struggles with weird-shaped gradients, I finally have a version that is somewhat acceptable. There are still a few gradients here and there, but that will be for another day.
SBIG ST-8XE on a Borg 76ED @ f/6.6 on a Takahashi EM200 mount.
Ha: 13 x 15 minutes binned 1x1 (16 exposures, 3 rejected)
R: 9 x 10 minutes binned 1x1 (10 exposures, 1 rejected)
G: 9 x 10 minutes binned 1x1 (10 exposures, 1 rejected)
B: 9 x 10 minutes binned 1x2 (10 exposures, 1 rejected)
All images combined using Sigma Reject Beta 10 (rejected images identfied in this software). Images acquired with CCDSoft. RGB image combined in AIP4WIN using RGB weights provided by Don Goldman's RGB calculator.
Post-processing and HaRGB combine in Photoshop CS.
This was a first attempt at a 1x1 RGB. The RGB alone is pretty cool by itself. But I probably won't be trying that again for a while. The HaRGB combine does not look as deep as other HaRGB's I've seen, I'm not sure what went wrong, but it's still satisfactory. For now.
The image can be seen at http://members.nuvox.net/~on.aunt/DSO/VeilHaRGB.jpg
Thanks in advance for any comments or suggestions.
