M106 multi narrowband
Posted: Mon Apr 19, 2021 1:35 am
My M106 project is finished. Not as planned, shooting broadband only gave way to orange/brown.
So it has become a multi narrowband capture: Optolong L-Pro (Ha, Hb, OIII, NII and SII) and L-eNhance filter (Ha, Hb, and OIII). In total 15 and a half hours of data.
And it's clear that the best filter, is dark skies
Below a cropped only of the core of M106 with the L-eNhance. Below that, the complete but scaled down to 2400px complete version.

Bortle 7/8
Meade LX200 8" f/10 ACF OTA
Ioptron CEM25EC mount (no guiding)
Optolong L-Pro filter
Optolong L-eNhance filter
Zwo ASI071MC Pro camera
Captured with SharpCap Pro @ -10 Celsius
Optolong L-Pro: 83 x 240 sec / Gain 10 / Offset 10 / White balance R50 B50
Optolong L-Pro: 31 x 300 sec / Gain 200 / Offset 28 / White balance R50 B50
Optonlong L-eNhance: 51 x 535 sec / Gain 175 / Offset 20 / White balance R50 B50
Stacked the 3 sets with DeepSkyStacker
Processed with Siril and Photoshop
Siril: each stack separately with Background Extraction and Histogram, saved as TIF
Photoshop: layered the 3 images with 50% opacity, Camera Raw Filter (blacks, saturation, clarity, noise reduction), scaled down to 2400px.
