Starlight Xpress SXV H16

hi DSI-friends,

I am used to OSC cameras from Starlight X-press.
I had a SXV H9C (sold)
and I still have my "beloved" SXV M25C.

for a couple of reasons I wanted to test a monochromatic CCD like SXV H16.
- is the luminance really so much better in a monochromatic CCD than in a OSC - pseudoluminance?
- I wanted to have a camera for usage of h-alpha and O3 filters.

well - here is what I have found out.

Hi Dietmar,
very interesting these comparisons of different cameras with noise. And also the responses with the SXh16 through the Astronomik rgb filter set.
I was a bit concerned when Terry had no choice but to go with the Kodak chips 'cause Sony wasn't making mono chips at these sizes only Bayer matrix colour chips. I thought, mmm will this mean darks will have to be taken.
Now I can see that a sigma combine would have no dramas... great.
Also the good and even light transmission over lap between r-g-b.

It has been my intention to buy the H16 purely as it is a good size chip for my setup as I won't have to step up to the 50mm filters and no worries with my 2" focuser, also the FOV won't be way to large for those smaller objects!

Thanks for the link.
All very good info.

All the best
