  • Hi, thank you for the interest!

    Equipment:

    • Canon 90d (no astro mod) ISO800
    • Canon 200mm f2.8L lens stopped down to f4.0
    • Star adventurer 2i mount

    As many 20s exposures as I could get that night.

    I use Siril for processing, been enjoying manual preprocessing recently actually. I stack and then follow a general processing pipeline I like: BG extraction, Photometric colour cal, then starnet++ star removal.

    I denoise in graxpert and back to Siril for stretching the data using GHS




















  • Thank you for your interest and compliments :) I was following advice from Nico Carvers channel for taking the frames: I am in a Bottle 4/5 sky so am decently lucky in that regard I took 400 light frames ( had to cull about half though) at 3sec exposure time to try and keep sharpess based on the NPF rule.

    For processing I used Siril and a lot of tutorials. I stacked the frames (minus flats because it didn’t like the ones I took), then ran background extraction, plate solved colour calibration, and then I removed the stars with starnet.

    I stretched the nebula using the generalised hyperbolic transform (I wanted to learn it, so far only used the others) and was happy with the results I got! My main trick was to do just enough stretching and reset the black point at each step, being careful about clipping. I then readded the stars at the level that I found aesthetic

    I don’t know too much yet, this was my 2nd astro project at all, but I really loved it!

    I just got a star adventurer 2i and the next clear night will have me doing Andromeda
