... Limit of star magnitude. If you want to obtain best results, you should use reference stars not more dimly than limiting star magnitude of your telescope. Limiting star magnitude depends on time of an exposition also.) This value should be set as " maximum of star magnitude " in a dialog box " Extraction from catalogue". To find darkest stars in the frame, make the following: . ... Two star magnitudes (m1, m2 in two photometric systems) will be outputted in the window "Information". ...
