I have been told by FLI that performance is similar to 8300 and 16803. I would suggest more like KAI11002 - around 50% QE and probably 25% in Ha or so.
Enough to make some lovely widefield images. Well depth is around 45,000 electrons which is less than half of a 16803 at around 100,000 but still plenty given the 8300 is only about 25000 and the Sony ICX694 is only 20000 or less.
The downside is it needs 65mm filters which if you get Astrodon then LRGB plus 5nm Ha is US$3105. Ouch. The Proline 50100 is US$15,995 plus exchange rate conversion shipping and GST.
You would really need to check out your scopes corrected circle as this one will need around 65mm. If its far away from the end of the scope of a fast scope it may need even more. AP refractors, TEC refractors, perhaps FSQ106 (not sure).
6 micron pixels would be a good match for 1500mm focal length or less.
This is a medium format sized chip and this chip is used in Hassalblad medium format cameras ($40000 or so).
Pentax 67 lenses should work with it.
