Here I have listed some of the various resources that I use for my photometry.
Astrometry upload allows you to upload either an image or FITS file, the website will then plate solve it and return an annotated copy of your image, listing known star names.
B-V Temperature calculator is an app which allows you to enter your calculated & corrected B-V colour index, and it will calculate the temperature of the target.
Airmass Calculator allows you to pick an observing location, date & time and will provide you with the airmass of the location for that time. Essential for calculating the calibration curves for extinction coefficients
