I am a newbie interested in starting doing stellar photometry. Sorry about the dumb questions but I need to make a decision about buying a used camera or not
I need help with the following questions:
1) How critical is the age and pixel column defect status of a CCD imager to the accuracy of the measured results ?
2) If the sensor has a large number of hot pixels, would this affect the measured results.
3) Can I use bias and dark frame subtraction methods successfully to correct for pixel defects ?
4) How many pixels are typically involved with measuring the flux of a single star and how will one or more hot pixels degrade the results to uselessness ?
5) How do you deal with column defects in photometry?
6) In principle would I be OK buying an old ( Ca. 10 years or more) CCD camera with some ( limited) sensor defects, or should I break the bank and go for a new class 1 sensor camera at the risk of annoying the CFO ?
7) I will be using a AT8RC F/9 ( possibly with the dedicated Astro-tech FR to achieve about F/6) with the camera, what is the best sensor size and type for such a scope.
8) Are CCD cameras worse or better than the modern CMOS sensor cameras on the market for photometry ?
9) Do newer CMOS based sensors have sufficiently linear response near the full well capacity ?
10) how critical is the antiblooming feature of CCD sensors to successful photometry, am I truely better of with a sensor with no antiblooming or is it possible to use a CCD with antiblooming by avoiding using the full well capacity and staying in the linear range of the CCD ?
Any help, ideas, suggestions are humbly sought and will be greatly appreciated
