Question about Flats for QHY163M, i know there has been a lot of discussion around this camera. But i am having a hard time getting a grasp on what i need to do to take Flats. At first my understanding is that i would use a lightbox (this one) and point my EdgeHD 11 at it (maybe with a TV Shirt) around it to dim the light. And then i would expose using time and filters as my light frames?
Is this accurate or is it different for CMOS cameras vs a CCD? Because when i've read from people asking about taking Flats with this camera or maybe CMOS in general, there seems to be an assumption that the flats only need to be a few seconds long?
