Since Alan bought the 2nd 1600x1200 Scorpion, the seller has a new listing for 2 more.

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.

Thanks again, Tim,
