Cygnus wall from the North American nebula (NGC7000). About 4 hours of total exposure with 5 minute subs. Optolong LeXtreme narrowband filter with ASI533MC-pro on WO ZS61.
@purisubzi I use SIRIL for calibration and stacking individual images and then Photoshop to do the contrast and noise adjustments.
@parag SIRIL is amazing. It really allowed me to exercise my inner nerd! I use Affinity Photo these days to calibrate and stack and found it works painlessly for almost all use cases.
@purisubzi Cool! Do you use stacking for astrophotography or some other purpose? Asking because I haven't seen any astrophotos from you since I started following you. Duh... It has been Monsoon season in India. Please share links to your photos. I'd love to see them.
@parag I do astrophotography, though not as regularly. I've posted a few things in the past (will comb through the archives shortly). I wrote about my experiments here.
