Hi Jeff,

I still have my DMK 21 series camera and don't expect to replace it with the PGR camera. The 640x480 array of 5.6 micron pixels in the DMK camera with 60 fps capture rate is a very good fit for planetary imaging. These PGR models on Ebay are wider field cameras (albeit with the capacity for imaging within a Region of Interest.) I expect the scorpion will perform very well for lunar and solar imaging and it will be great to sample a product from PGR at this very low price. The PGR products have always been way considerably more expensive and with a wider feature set than those from the Imaging Source. I guess someone with more experience can say whether one is a clear winner over the other. I've had good success with my DMK cameras thus far.

Your filter wheel and nosepiece from DMK camera should all be fine with the PGR camera.

I think I know the answer to this, but for the price, would this be a worthwhile upgrade from my DMK21AF04.US? I assume I could sell the TIS camera to help fund the modest price, and my existing 1.25 filters/wheel would still work.
