I am looking at perhaps getting another camera (oh gawd not another one) for my setup.

I see Roland Christen of Astrophysics uses a QSI 683 wsg 8300 for his Honders. It does work out to .96 arc seconds per pixel which he recommends for the average user (assumes 3 arc second seeing).

I have been impressed with QSI8300 images and the built in OAG and filter wheel. Additionally although the 8300 is not a good match for my CDK17 the short backfocus of 36mm means I could use it with the reducer which has an optimum spacing of 44mm (real workable right 44mm what were they thinking of??).

I have also thought the KAI16070 looks like a nice sensor and images from the Cedic team using that on an RCOS 14.5 were very good indeed.
Whereas images using the FLI Proline 29050 mostly looked terrible. Not a comment on FLI cameras at all as they are great - just the sensor.

The QSI with the 4022 sensor with 7.4 micron pixels may be a good compromise. It is 15mm square so a bit bigger than the 8300 sensor, slightly lower QE than the 8300 but not much at 55% versus 60.
Bigger wells, probably better dynamic range. It may suit the CDK17 with reducer as well as work with the Honders at 1.32 arc sec/pixel versus .96 arc secs/pixel with the 8300.

The 694 sensor is very good but a tad small. It works well on the Honders at .81 arc secs/pixel and I think its ideal for small galaxies and nebulas with its superior read noise, high QE in narrowband (twice as sensitive to O111 than the famous 6303 sensor).

The 6303 sensor is always interesting. Blooming though sounds like a pain and I can always do subframing on my 16803 to emulate a 6303 with mostly superior performance to the 6303 (lower read noise, slightly lower QE but close and no blooming, larger wells, longer lasting sensor).

Sony makes an APS sized sensor but it one shot colour only. Bugger. It would be perfect. Maybe some brave person can debayer one.

STXL11002 with AOX is appealing. Martin Pugh loves his and its a proven performer. Reliability and mature system though is unclear with the takeover. Also I think it suits those who have mega hours available to overcome the lower QE at 50% max and 30% in Ha or less. It would work well on the CDK17.

FLI also make a Microline 16050 which is APS sized. It has slightly lower QE, more like an 11002 but APS is a good size for me I think. That is a possibility. If it doesn't work out though resale value would be a concern as its not a known type of sensor.

What do you think is a good camera at the moment?
