Question for Master Darks and Flats

Hi @Niraj Dave

Yes You can create Calibration frames in tab 2) Calibrate using button "Create Masters and Assign to lights" Without any lights loaded, the process will simply stop after creation of Master Calibration frames and BPM. However You will be able to inspect the created Calibration Masters even after normal integration including lights by double clicking 

Master Darks are good enough for 1 year or more, the same is for master DarkFlats (please note both need to match exposure time and ISO / gain/temperature of the lights resp. flats). Also Master Bias are long-lasting

Flats should be taken after each session to accomodate for issues varying with each session like camera rotation, filter change, dust bunnies etc. 

Hope this helps

Clear Skies,

Jochen

@mrkhagol Adding to Jochen's excellent reply, it is possible to not have the darks match the exposure time of the lights and/or darkflats match the exposure time of the flats. In that case you need bias as well. And in that case you can omit taking darkflats since the darks can be scaled to the exposure time of the flats. 

Thank you for the responses and bit more clarification. Really appreciate it. 👍
