Thanks Bruce,
I hope not to be the only one benefitting from this sequence.
Thanks and appreciation again go to you and especially to Arne for another calibrated field.
Tonight I will compare your sequence with the one I derived from the same data file. I have used DSS images (of both generations) of the field. They allow appropriate reference star selection.
Regards,
Berto

For Berto, here is the sequence for V2400 Oph, derived from Arne's
recent field photometry. As Arne noted, this is a crowded field, and
I had to be careful to select stars that were not affected by close
neighbours. The field is also quite red, and I had to include two
stars, namely 9 and 10, that are really too red to be included in a
normal sequence, but because of their proximity to the variable, and
because there were no other suitable stars near these magnitudes, I
had to include them in this sequnce. Do use them with care.
