Ok this is my take on M74. The galaxy is located in Pisces and it is about 32 million light years from us.
I imaged this galaxy between September and November of last year. I had some data from 2015, but was not on par with the recent data set, so I only used the recent data.
here are the settings:
- Edge HD 9.25 on CGEM
- UnMod Sony a7s
- Light Subs (18 hours 33 minutes3 0 sec) 2,227 x 30 sec Subs. Data from 5 Nights
- ISO 6400
- Calibration with dark, flat and bias images
- Registering & stacking with DSS 4.10 64Bits
- Post-processing in PI with pseudo luminance channel.
- Red Zone
