Despite the awful weather recently, I was able to capture this cosmic traveler possibly for the last time as it is currently sweeping by us and headed into the void again.
12 days after my first attempt, it seems to have changed a lot visually and picked up a lot of speed. In a span of 3 hours, it covered roughly 1/4 of my field of view (3°x4°), compared to only 1/10th during my
first try. The almost full moon made it challenging to process but I think I was able to pull out what I could from the data.
L: 46*60s
R: 46*60s
G: 46*60s
B: 46*60s
Processing workflow:*Mono
COMET:- Calibrate and register images (on stars)
- CometAlignment on registered images
- Batch StarXTerminator on comet aligned images
- ImageIntegration starless comet images
- *Repeat on all filters if necessary
- *CometAlignment again on all comet stacks
- Processing as usual
STARS:- *Combine registered RGB images
- DBE/ABE, PCC/SPCC
- StarXTerminator and keep only star image
COMBINATION:Combine fully processed (and stretched) starless comet and star image:
- Pixinsight: Pixelmath "~((~starless)*(~stars));"
- Photoshop: Star image on top using "Screen" Blend Mode
