Deep Sky Stacker Frame Quality Scores

[Starwiz]

I've been using a score of 300 as the minimum quality for including an image in the stack.  There's no scientific basis other than it just 'feels right' for me.

I'd be interested to hear what other people use and reasons (if any) for choosing a minimum score.

Thanks

I look at the peak score then how the scores spread in the stack and ditch the lights that are obviously below the bulk range. For me the ones that score low on inspection are cloud or star trail effected to a point I consider detrimental. I'd have to load a stack to see what the score was but it's likely around 600 and lower, though I use the FWHM as well.

Thanks.  Sounds a bit more scientific than what I'm doing which is probably gut feel at the moment.
