Novadel I mag

Hi all ,

I did photometry in U , B , V , R , and I Band

For the I band i choose 000-BCL-374 which is the alone star with a Imag in the field of my camera .

The problem is that a 9.9 mag star and have a very bad snr, and my measure is not precise.

Where can i find a better reference star ?

Thanks you

Thibault, Most of the


Most of the brighter comp stars near the nova are in the Hipparcos catalog and have V-I as well as B-V colors listed.  What camera and instrument are you using?  Is your FOV wide enough to take in any Hipparcos stars?
