[Aavso-photometry] Transitsearch Opportunity

[Jean-Luc]

Hi Aaron,

Maybe a very naive question : HD 80607 seems to be a G5,  V 9.17 star, 
very similar to HD 80606 (G5, V 9.06).
Separation between the two is 21,1" according to WDS. It means close to 
7 pixels with my 8" SCT and F/3.3 reducer but
up to 24 pixels without the reducer.

Why can't we use HD 80607 as a comp star for HD 80606 transit search ?

Thanks,
Jean-Luc
