Hi folks,

I can't seem to find any comparison AAVSO stars for DD CrB (aka NSVS 07826147). I've looking at about 30' FOV down to mag 15.

I have my own from APASS that I'm currently using but would like to use some approved AAVSO stars if possible.

Is this the right place to ask? Apologies if not.

Best Regards
