Thanks Paul that is very helpful. I had a short clear spell when I got home from work and managed to capture a series of images of varying durations of a star field.

I’m just looking at the images now and identifying the stars in the image and their magnitudes.

What do you use to measure the SNR of a particular star? I have pixinsight and I can see the ADU values of the centroid and the background, is it simply a case of taking the ratio of those two values?

Thanks again
Craig
