Practice Images for CCD Photometry?

  1. Nov 5, 2015 #1
    Hi, it seems astronomical FITS images are abundant on the internet. However, I am looking for FITS images of bias/flat and standard stars along with observations to practice CCD photometry and having a harder time.

    I would like to be able to take a set of images and obtain the transformation equations in UBV, for instance (using IRAF tasks). Does anyone know a source of FITS which includes bias/flat/standards?

    Still looking for a good source of FITS with object, dark, bias, flat, standards, etc.

    I contacted my local university's astronomy department as well as a nearby observatory hoping for a public archive of some sort. No response yet, I suppose its a weird thing to ask...

    I also found the IRAF example files which includes a few image sets.

    Well, with a little fiddling I was able to figure out NOAO's public archive to get a full night's worth of data from some random run 5 years ago.

    Not sure this is the best, but it was quite usable with a java based download manager for grabbing the 410 files (1.4 G) worth of data.
