Image taken from the balcony in Brisbane City during 9 sessions in October-November 2021.
Bortle 7 sky ("red" light pollution zone).
First light of my new ASI2600MM-P camera on TAL-250K (10" Klevtsov-Cassegrain) with 0.7x recucer/flattner MkII (F/6). EQ6-R mount.
Total exposure time is 17 hours, Sensor temperature -10°C
16 hours (180s subs) - H-alpla, SII, OIII,
1 hour (30s subs) - RGB stars
I made classic SHO (Hubble Paltte), then separated the stars, applied RGB colors to them and added em back.
