Just starting out with DSLR photometry. I seem to have image acquisition and calibration sorted.
Split the image into RGB channels - using only green at the moment.
Using Iris to perform ensemble photometry. I can generate the instrument magnitudes for the comparison and check stars however I am not sure which published magnitudes I need to use. Do I use the labelled magnitude on the AAVSO charts or do I use the "V" magnitudes from the photometry table. The results are not transformed at this stage. I would like to report "TG" magnitude for the present at least.
Thanks in advance

You would use the V magnitude from the photometry table.

Thanks.
I assume I select Johnson V as the filter on the submission form or ??(unfiltered zeropoint V)

Figured it out
