All data acquired and integrated/stacked in my own custom built imaging suite I've been working on for a year. First image captured end to end in it.

Integration: 27 h 19 m 30 s from 824 exposures.

L: 179 × 90 s = 4 h 28 m 30 s

R: 185 × 120 s = 6 h 10 m

G: 189 × 120 s = 6 h 18 m

B: 190 × 120 s = 6 h 20 m

Ha: 81 × 180 s = 4 h 03 m

GSO 10-inch f/4 Newtonian and ZWO ASI1600MM-Cool, bin 1×1, cooled to -10 C. LRGB: gain 76, offset 15. Ha: gain 139, offset 21

Processed in PixInsight: separate RGB, luminance and Ha preparation; GraXpert AI background extraction with protected residual background modeling; APASS photometric color calibration; BlurXTerminator followed by NoiseXTerminator while linear; StarXTerminator for separate star processing. Ha continuum was estimated from field-star photometry before restrained emission blending.…
