[vsnet-obs 70442] Image of SN2011by

[Michel Favret]

Hi !

I'm french and I hope you will excuse my poor English.

Last night, I took a picture of this SN but I don't know if it could be useful because of the very simple hardware used (a Celestron
C8 SC, 6.3 F/D reductor, EOS 20D), the short exposure (20x1mn at 800 ISO), and the basic method of mesuring with Iris software
(dispatching the GRB pixels of the Bayer matrix with split_cfa, "registering" and adding the 20 frames of each color, mesuring
fluxes with the GSC3836.118 star as reference).

You can have a look on my message posted in a famous french astronomy forum (texts are in French but pictures are self-explicit) :
http://www.astrosurf.com/ubb/Forum3/HTML/029842.html

If useful, I can send you pictures or mesured fluxes.

Bye !
