RE: [MaxImDL] Question about Auto Darks

Hello:



I have a question. Which is better to do ?



In the CCD control window, under Settings, you have the option of using Auto

Calibrate, [None-Simple Auto Dark or Full Calibrate]



Is it the experience of users to use this or not. And just use your darks

and biases to clean up the images ?



Does using the Simple Auto-Dark degrade from the sub frames in any form ?



Also on one of my images I got a cross like effect that occurred out of the

blue. It was from some kind of flash.



I didn't see any airplanes or satellites, so I wonder what caused this. I

hope I don't have a problem with my ST8XME.







Thanks

Sam,



My usage is to take darks, flats and bias after or before imaging. Take many

darks and median combine the darks. This allows you to image as long as

possible. So the short answer is not to use auto dark of full calibration

but calibrate all images after you finish imaging.

Hi Steve:



Okay sounds good. Should I do the same for the flats too, take darks for the

flats ?



Thanks for your help.
