Since the last SAS meeting I've been meaning to ask you, filtered or unfiltered? I assume for photometry purposes later on you would need at least a V filter. Also, do your reference images match in terms of filtering? A "hot" star may show up brighter in an unfiltered image, for example, than it would if an IR filter was in place, so if you are using a survey as your reference this would need to be taken into consideration.

Also, what are you using to cross check against variable stars?

Regards,
Eric
