Camera recommendations?

So there are load of cameras...what are the best for dso's with a small refractor?

Im looking for the entry level cam with big enough sensor for wide field

What is your telescope diameter and F ratio?

If i have that infomation, that would be easier to recommend.

I have the celestron 6 inch Sct with a 0.63 reducer. So 945mm fl.

Thanks

Here is some example that simulate the FOV in Stellarium, hope it can give you some reference.

And this is a tool which can calculate the suitability of the sensor and telescope.
