[edit] Calibration frames
Beginner scopes (Snap-Shot Astronomy): Calibration frames are applied automatically, and both the raw and the calibrated image are saved and can be downloaded. Calibration is done with a master 5-minute dark and a master bias frame, both at the same temperature as the image. You can download the master calibration frames (and in some cases additional frames) from the link under "Calibration Frames" for each scope. Some scopes also have flat-field frames available at the calibration frame link. These are not currently applied automatically, however, and must be downloaded and applied yourself.
Advanced scopes (Astronomy Studio): Calibration frames are not applied automatically, except for an auto-calibration for focusing, centering, and guiding. You can download a wide variety of master calibration frames from the link under "Calibration Frames" for each advanced scope. All advanced scopes also have flat-field frames available at the calibration frame link.
Note: If you are unsure of image details, such as binning or sensor temperature, this information (and a lot more!) is stored in the header of each image. You will need software that can read the image and its header (e.g., MaxIm DL, CCDSoft, FitsLiberator, etc.) to view this information.
See also various links related to image calibration and downloads on the list of available wiki pages.
