Note that the TAC would prefer to have images taken in B,V,I filters rather than just V.

I think the recommendation is to take images at V and Ic, so that there is color information and the opportunity to transform the data. The problem with B images is that the star is faint, and in addition, there are two close companions just to the north that will interfere with good photometry. So at least, use V and Ic. If you want to try B as well, no problem, but just be aware that photometry will be difficult.

Hi Dirk and Arne, how do you recommend, please for photometry in V and I. I don't feel comfortable with B now. Thank you very much.
