Flaming Skull Nebula
« on: 2018 February 04 18:48:15 »
Hi,

Although I took this image last year, I thought it might be a good idea to post it since I used a recently discussed technique:
(click image to go to the page)



Optics                                        32-inch Schulman Telescope (RC Optical Systems)
Camera                                       SBIG STX 16803
Filters                                          AstroDon Gen II
Date                                            May - 2016
Location                                      Mount Lemmon SkyCenter
Exposures                                  HaLRGB = 12 : 15 : 9 : 9 : 9 hours
Acquisition                                 Astronomy Control Panel (DC3 Dreams), Maxim DL (Cyanogen), FlatMan XL (Alnitak)
Processing                                  Pixinsight

I used Fabian Neyer's technique to remove stars from the H-alpha image. Then when I blended it into the red channel (I used my method of "screen" blending)- I did not have to worry about the Ha contaminating the RGB stars. I think all worked out well and I was very pleased to detect some of the tendrils in this nebula that show up in narrowband imaging so well.

Nice one, Adam!  I almost always do star removal for NB colour these days.
