Yes, I agree that size would be useful to find best target for a telescope. Both size and magnitude are in my to-do list. Simbad seem to have a field “Angular size (arcmin)” so maybe I could use that. I need to create a small program to query Simbad and add size to the my catalogs so it can be used for filtering.
i test the new version , size seems ok , but i cant get it in the same time as Moon Avoidance calcultation .
if i select size > 5 , and after moon avoidance , the selected number of ngc object dont change
Moon filter works so that if you do not have a time selected then if the target matches the moon filter at any point of the night it will be included. If moon sets at some point during the night then targets are likely to be included. Could that be the reason?
I have now updated all catalogs to include size. If size is not available it is zero.
