Description

Shot from ''millian stars hotel'' Deepsky Villa Karimunjawa Indonesia.

AND my first contribution here.

Frames: 74 x 120 seconds and 55 x 180 seconds, plus 23 darks of 120 seconds and 25 darks of 180 seconds, 60 bias, 30 flats (5 seconds) and 30 dark flats (ditto).

Telescope: William Optics FLT 132 at F7
Mount: 10Micron GM 1000 HPS
Camera: ZWO 294 MC pro, gain 121, offset 30, cooled to 10 degrees (night temperature is always around 27-29 degrees here).
Filter(s): none
Autoguiding: none

Edited with PixInsight. Blink and subframe selector. Then first tried full registration with WBPP but then went back to the process up to and including debayer.
From alignment per step done manually. ABE and crop applied (just cropped a bit), then DBE, color calibration, denoise, saturation, sharpened and HDR MT.
That PI will still be difficult for me, so some artifacts around the stars.
Tips always welcome
Thanks for looking.
