KAI16070 sensor

[gregbradley]

I noticed a recent image was done using a FLI Proline 16070 camera. So I looked up this sensor. I think this is a fairly recent sensor True Image has put out.

7.4 micron pixels and 15.7mp in a 35mm sized chip. Other specs seem very similar to the more usual KAI11002 sensor which has 9 micron pixels.

I guess it would suit a shorter, faster focal length scope where the corrected circle or the preference of the imager is for rectangular images.

Another choice when making a decision about cameras. Instead of the usual KAI11002 you could opt for a bit more resolution with much the same QE etc (48% versus 50%).

Greg,

That's an interesting pixel size. It would be a reasonable match for my Ceravolo at f/4.9 but way oversampled at f/9. Not a bad match for a FSQ-106 either. I do like the extra physical size of the KAF-16803 though!

Cheers,
Rick.

Greg this looks interesting, maybe they glued 4 4000 chips together they are also interline with 7.4 micron pixels. At least it should have a better full well than the 8300. I would be interested if manufactures kept the price reasonable.
Clear skies Ken.

I've been looking at this sensor for the CDK12.5, given the results I've seen with 4022 sensors. The pixel size is a good match with AO.

Yes it looks like it could be ideal in some setups. I don't think its a serious replacement for a KAF16803 chip with nearly twice the FOV and 12% better QE and more than 56,000 electron deeper wells.

Another chip to consider is the KAI29050. It's roughly the same size as the KAI11000 but offers 29 megapixels sized at 5.5 microns. QE is roughly the same as the KAI11002. The one drawback of course is the shallow 20K full well depth, a result of its small pixel size.

Richard Crisp has used this chip and likes it. If you search the web a bit you can find some images Richard captured with the 29050.

For fast astrographs and with good seeing, the image scale of the KAI29050 works out quite nicely. For example, for the RH200 with its 600mm focal length, the image scale works out to be 1.89 arcseconds/pixel.

I was very interested in the ML29050 at one stage. The small wells are my main concern. I saw Richard Crisps IC shot. Some of the brighter stars there look like my Trius 694 and TEC180 - a bit bloated. Not everyone finds that unpleasant but I prefer to not have it if I can.

I'd like to see more examples. On paper it sounds like a good camera for a fast scope for widefield imaging.
