Gstar-ex
Hi Kev
Yep...that's a very GEM camera look. Actually a MTV-13V1.. I used one for quite a while and despite the hot pixel constellations (as you put it :-) it served me well for some time but it has the Panasonic chip set which is not as good as the Sony chipset and not as sensitive near 1-micron which was one of the great benefits I found that enables me to image the thermal emissions from the night side of Venus. Although you are much farther north, the hot pixel spread in your GEM image looks pretty much as I experienced down here in cooler seaside Sydney. I have attached a stacked dark frame full res for you to compare (it's not a single frame as I discarded those after stacking the dark frames) however it still shows the hot pixel spread at full integration nonetheless. You'll also notice how the amp glow is greatly reduced (limited to only the top left corner). I've also attached a rough version of NGC5128 to give an idea of the view after stacking 50 unfiltered images and subtracting the dark frames. Unfortunately I have cropped the final result a little.
The GSTAR-EX is a vast improvement over previous Mintron designs and is better and cheaper than the U.S based StellaCam.
