M33 Triangulum
This one didn't come out as well as I had hoped after collecting 38 x 5min subs at 1600iso. Maybe the low altitude angle didn't help, I know my guiding graph was a bit up and down as well perhaps due to the seeing.
After integrating with darks, flats and bias, the image was basically bright red right across the image with whiteish parts of the galaxy visible. I am not sure why this was the case? I did have a red head torch on as usual but don't recall ever shining it into the scope. After DBE most of the red was gone but I was still left with a faint but very visible red blotches/mist throughout the image background. I tried Background Neutralisation and Colour Calibration but not much effect. I also did ACDNR after stretching but not sure this helped that much either.
Appreciate any advice on this.
Processing in Pixinsight and PS.
Thanks for looking.
