Ok, first impressions from use on the scope...
The pixel size of the flea3 is 5.6 microns (same as the dmk), but different to my current dragonfly2 camera which has 7.4 micron pixels, this makes it tricky to compare the cameras, I have to change barlows etc and try to get the image scale equalised between the two cameras so that the image brightness can be properly compared.
I didn't quite succeed, so the tests were done with an image scale on the flea3 about 10% larger than the dragonfly2. This should mean that images will be a little dimmer than they ought to be.
But in any case, the flea3 has massive red sensitivity, at least 50% more than my current dragonfly2, maybe more than 50%. The green sensitivity is also higher, but not by as much, and the blue sensitivity is about the same between the cameras as far as I can tell, but again the slight differences in focal lengths in the tests makes it hard to be exact.
Another complicating factor was thin cloud that kept drifting through, again making it hard to get exact measurements.
But there's no doubt that I'm keeping this camera... the red sensitivity is amazing.
Just for laughs I switched to my ir742 filter, and at 30fps and a large image scale Saturn still showed quite a decent image, again very surprising.
The only downside at the moment is that my capture software (coriander) doesn't completely understand the flea3, so the gain slider refuses to go to more than about 60%. Thanksfully I can switch it to absolute mode and type in the max value by hand. I guess I have some hacking to do to get it working properly.
cheers, Bird
