Hi all,
I am after some advice. I am keen on getting a new camera (monochrome) and I am tossing up on a couple of cameras. Before I get to the options, I have a couple of constraints being:
1. I use a PROSTAR 102mm F7 ED Refractor (similar to a William Optics Scope) and a Stellarvue 80mm ED Refractor as my two scopes for imaging.
2. I use an ATIK Electronic Filter Wheel with 1.25 inch Astrodon filters.
The cameras I am looking at are:
1. Starlight Xpress SXVR-H16 USB 2.0 CCD Camera System (mono)
2. QHY-9 Large Format Mono CCD Camera
3. Anything else on the market up to $5000 Australian Dollars.
My concerns are that there may be image distortion due to the size of the CCD chips and that I may need to invest in a field flattener (although I don’t want to).
Can anyone give me some advice?
Cheers
Robert
