Camera is a Sony SLT-A77 with a Samyang 35mm f/1.4 lens.
I live in a fairly light polluted area, shooting from the backyard.
I used Long Exposure NR Reduction on the camera.
ISO adjustment LOW. (only has low, medium, high).
I took from between 6-9 images, and used DSS to stack them using just the default settings. No use of dark files, flat files, dark flat files or offset/bias files (no idea what they mean yet).
I have attached a small 100% size cut of the imaging.
Some questions:
When I used the RAW pictures I took, DSS barely recognised many stars. When I used the camera processed JPEGS, it recognised hundreds.
DSS Scored my final pic 4326.51, then threw it down to 827 when I changed the aperture to 1.4 lol.
What can help me improve?
How many pictures might it be good to have in a stack, realistically?
