Which comments? The ones about not buying a QHY8 or about the 8300 also being a good chip or something else? It has been a pretty busy thread and Chris only got back from a 9hr drive on Sunday night, so has been pretty flat out. I don't think you are being deliberately ignored, there just wasn't a lot to specifically reply to maybe, or he hasn't read and absorbed it all yet and is head-down bum up trying to come to grips with the camera.
I think Chris said he is looking at an 8300 as well in one of the posts, and he is only trying the QHY8 as I offered to loan him one.
The main point of the exercise is to see if it is worth spending his limited resources on stepping up to a dedicated cooled CCD camera of any description vs his DSLR, the QHY8 is a good way to try it and see. It will have similar performance to any other OSC cooled CCD, others may be a bit better or a bit worse, but the setup and use and results will be similar and help him decide whether to stick with the DSLR and spend money on something else, or purchase a cooled CCD of some description.
If going the CCD, the decision of *which* camera to buy will be a whole 'nother thread of agonising over choices I'm sure
I think Chris' main issue at the moment is with processing files with a wide dynamic range, and the hoops that have to be learned and jumped through. Some help in that arena would be appreciated from anyone, it isn't my strong-suit.
