Thanks John - I’ll try your suggestions on the next clear night. In the meantime - building on your suggestion, I checked the SEP parameters in the Focus Options Profile Editor (next to the 1-Focus Default option). I see that the SEP star selection is set be default to cut the brightest 10%, cut the dimmest 20% and cut any stars above 90% saturation. I’m going to try cutting, say, the dimmest 50%, keeping the brightest, and retaining the saturation cutoff. Just a thought - if the code then cuts an additional %, there may be a degree of overkill on whittling down the set of available stars.

I see that the guide module and the align modules retain pretty much all stars - the ‘cutoffs’ are zeroed.

Thanks again for your suggestions and help
