Qsi 583

[Paul Haese]

Thanks Theo, that is good sound advice. Will do the tests and report once I get that sorted.

Paul,

I have been using the 8300 chip for some time now and I like it. Perhaps not too long exposure times as the bright stars can look a bit bloated with the small wells of the chip.

Otherwise it is a fantastically able chip.

I use colour combine ratios with Astronomik filters of 1.3 1 1.9 for RGB so Theos comments seem correct to me.

How cold does your QSI and does that have the built in off axis guider?

Greg.
