[Daniel Self]

Hi,

I tried photometry of SN2011at in PGC 26905 with a Canon EOS 1000D modified
DSLR camera.
Attached jpg is a linear stretch of G channel.

Exposure: 15 x 1 minute exposures (calibrated) at f/3 on a 500mm newtonian
Location: 52.5N 0.5E
Notes: I used the Green channel only, as an approximate V filter (according
to AAVSO.org)
Catalogue: I used 21 reference stars from Stellarium catalogues 12.4-14.8m
Error(1-sigma): +/- 0.13mag
Software: Iris v 5.57 - aperture photometry
Air mass: 3.14
