Ever since Last years imaging of this region, I've been itching to go back to this with a bit more purpose. I settled on a 3-panel mosaic of the region incorporating the entirety of the witch's broom, Pickerings Triangle, and what I'm calling the "Scorpion's tail." (please let me know if it has a name). Eventually i may supplement this with another more imagery of the East Veil, but that might have to wait for now.
ASI2600MM, Antlia 3nm OIII, Antlia 4.5nm Ha, Antlia Pro RGB (for the stars)
Takahashi FSQ-106ED on a ZWO AM5.
For each Panel:
- 15sec x 60 for each RGB for the stars
- ~4hrs each for Ha and OIII.
Stacked in WBPP @ drizzle 2x.
Each master stack was Gradient corrected, then put together using the PI Mosaic tools.
RGB was RGB combined, solved and SPCC, then BlurX, and stars extracted. Stars were stretched with GHS
Ha and OIII was ran through BlurX, StarX and NoiseX, then stretched with GHS. Combined with some pixel math. Curves transformation to taste, then mixed with a synthetic Luminance made from the OIII and HA, then stars added back.
It was definitely a bit of an arduous process, and doing a 3 panel mosaic at Drizzle 2x files is right at the limit of what i think my current processing setup can comfortably handle, though i am currently brewing a 4 panel mosaic of a different region of space, so that will be a real test.
Be Sure to check it out big on Astrobin!
Enjoy and Clear Skies!
Question: how do the colours look for you? I've got wildly differing result depending on the monitor i'm viewing it on.
