We got a small reprieve from the June gloom and the local astronomers rejoiced. I decided to start working on
NGC 6888, the Crescent Nebula, as the constellation Cygnus is nicely positioned in my sky. I captured 55 subs each in
HA and O3, 300sec, 120 gain, over 3 nights.
After the the second night, I did a quick process and noticed a new dust mote had shown up on the image. "I should have taken another set of flats," I said to myself. After the third night, and a quick process, there was the mote again. This time, with a little more data, I noticed it was a bubble! I bumbled upon the Soap Bubble, (
PN G75.5+1.7). Doh!
I've cropped this tight as I wanted to highlight the bubble. This image was processed entirely in
PI which is new to me and tackled Pixel Math for the first time. I did a couple small color tweaks in photoshop but that was it. I am thinking of trying to sharpen it a smidge, but so far results have ended in disaster. I also have a set of
RGB data that I shot with this that I'll try and fold in. I now have plenty of post-processing projects lined up for the inevitable return of the gloom.
Let me know what you think. Any
PI tips for improving this would be much appreciated as well. Clear Skies.
