Perform the most precise photometry possible
We will attempt to perform the most precise photometry possible using FotoDif (the classic version, not FotoDifSN) and the comparison stars proposed below. We must use all three comparison stars . - Tycho can also be used. - Multiband photometry is appreciated; it has a very different behavior in B and V. - Look, it's a bright star. Be careful not to oversaturate it; a slight blur might help. - We recommend reading the tutorial on how to perform good photometry, which we have on this same website . Right now T CrB is still an object for the end of the night, although from 2 a.m. onwards it already has a decent height. Thank you for your measurements!
