Filters - A worked example
Hi Brainy Ones :-)
This example is using a colour camera.
I am ignoring using RGB filters.
When stating RGB below, it is straight from the camera (no filter).
After looking at images in Astrobin and IIS, there seems to be a few ways of taking the images (that I can use):
1: RGB
2: RGB and Ha
3: Ha, OIII, SII
4: RGB, Ha, OIII, SII
Worked example:
We have 2 nights (3 hrs/ night) to image Andromeda (guided).
My plan (method 2):
3 hours Ha. 3 hours RGB
Exposure times:
20 of 5 minutes, 20 of 2 minutes, 40 of 1 minute
Sooo... what would be your plan?
