Description

Composed of 134 x 90s exposures at f/3.2 iso 800 (intended to shoot at f/2.8 but star sharpness probably benefitted at cost of nebulosity?). Processed in Siril only as I have lapsed on the expensive Lightroom plan. After stacking (included dark and bias frames) and calibration I stretched with the asinh tool then a bit of GHS and finally slight shift of the black point.
