Hi All
I'm not all together happy with my first attempt at Rosette Nebula
https://photos.app.goo.gl/gEz14s38EHZymXCaA
My equipment is Nikon 5300, WO GT-81, Losmandy G11, Optilong L-enhance. Bortle 4 skies.
The image is over 4 hours from 6 min subs and I was expecting more.
There is far more noise in the image than I was expecting especially in the red channel.
Looking at the histograms of the channels coming out of DSS+ (and off the RAW files) the red channel is significantly lower than the green and blue.
I'm guessing this may be due to the DSLR IR filter in combo with the L-enhance???
Anyway there was a screw up with taking the dark images (I know what the temperature was so I'm going to recreate them eventually). So that may be part of the problem but I have some questions with the ISO.
I was shooting ISO400 before I used the L-enhance but I found that 2 min subs had too many black pixels in the red channel (seems to screw up DSS+ somehow). Swapping to ISO800 seemed to fix this but now I'm wondering if that is the wrong choice.
Anyway any advice would be helpful.
