How do you think it is for me I just bought a mono ccd, I have a scope that could make use of that camera, but alas, I need to curb the spending for a little while.. Had it come for sale 5 months ago..

Terry, I havent seen that, thats very interesting. I notice the total noise for a 9e read noise cam (ST10) doesnt change much from -5 to -25, you have to go way past that to make a big diff (pg 25, with 20min exposures, common for me), and the 6303 is 13.5e !. He says somewhere very deep cooling doesnt help hi read noise cams as much as the 16803, as the read noise dominates.

I can see now why I get a fair bit of noise with 20min exposures and very low signal ADUs with the ST10 regardless of temp below -10, and the value of deep cooling with a low read noise cam, it all makes sense now ;-).

Yes, thats a nice cam kit there for sale, but for me (just me), the Qe is a concern. For anything other than dim, long FL very NB megdata though, its fine.

Hi Fred,

I'd go the 6303 for your setup. Kodak hasn't been able to better that chips performance in QE since. They have improved in other areas but the 6303 is still a really great chip with lots of great images on the net.

It also seems to be the narrowband imagers camera of choice.

STL6303's will no doubt be cheaper as the existing owners upgrade to an STX.

I think a 6303 also gives a nice image scale for a 10 inch RC. You should be able to get plenty of detail in galaxies etc.

Greg.
