Post here if you are (or will be) measuring SN 2011fe
I know that a number of people are contributing to the AAVSO's light curve of this supernova. If you are one of them, please post the details of your setup here. This may help us to figure out how to combine your data with that of others best, and it will also help new observers to figure out what they need to do the job.
I'll start: Michael Richmond, at the RIT Observatory in Rochester, NY. I am using a 12-inch Meade LX-200 with SBIG ST-8E CCD camera and Johnson-Cousins BVRI filters. I find that 60-second unguided exposures yield untrailed images about two-thirds of the time, so I take 10 or 15 images in each passband and analyze the 6-10 good ones. Simple aperture photometry with a radius of 3-5 arcseconds seems to be adequate, so that's how I'm extracting magnitudes from the images. I'm using the AAVSO's comparison stars from sequence 5249bgj. You can find many details at the web pages I have written for each night's work -- look near the bottom of this page:
