This is just shy of 30 hours of integration with an Askar SQA55 and a Canon EOS 7DMK II (ISO1600, 60 second exposures), from Bortle 5. I am using my Skyguider Pro as mount and manual framing was tricky, though tracking was mostly fine with a good PA. Processed in Siril and PI:
- Calibrated with darks, flats and biases
- Spectrophotometric Color Calibration
- Applied color correction matrix
- GraXpert for gradient removal, followed by BlurX and DeepSNR
- Initial Arcsinh stretch
- Removed the stars and used masks+curves to bring out the IFN (also reduced the saturation on the background a bit)
- Added the stars back and did some final adjustments with curves
