I have been experimenting with software tools for data processing and have a couple of observations:
1) If you are not aware of the tool, ASTAP, it offers incredibly fast plate solving, FITS conversion, and binning batch processing options. It will plate solve an image in around 0.5 secs! It also displays magnitudes of all known stars in an image, the location of variable stars in an image, and even attempts to identify unknown stars in an image.
2) In Astrometry.net, can someone clarify the meaning of the red, green and co-located circles in the red-green plot?
3) For small FOV images, is there an online tool that will take the image and identify star magnitude and color/temp to aid selection of comparison stars.
My FOV is small (30x30 arc mins) and the AAVSO 'finder chart' often indicates no comparison stars?
