SkyNyx
David,
The SkyNyx 2.1M is a bit hefty in price, but thats the only downside to it. The SkyNyx series come in the following models
2.0 model (640 X 480 with 7.4 um pixels)
2.1 model (1392 X 1040 with 4.65 um pixels)
2.2 model (huge chip with lots of pixels, 4.4 um in size).
I bought the 2.1 since I could afford it and didn't need to use a higher f/ratio than with the ToUcam. This is because the 2.0 model has larger pixels than a ToUcam. The 2.1 has smaller pixels than the ToUcam and the 2.2 has even smaller pixels.
The noise is extremely low. Download is limited to 15 fps but thats adequate. Most telescopes don't collect enough light at high f/ratios to be very useful at 30 fps. It is light, easy to use and can be used for long exposures too - I've seen some great deep sky images taken with it.
I briefly thought of getting the DMK 21F04 but ultimately, the SkyNyx won out even though it's much pricier. And I'm very happy with it.
Zac
