Since I can't get an ST-10XME before August, I must withdraw offer.
ST-10E. I am purchasing an ST-10XME and would like to sell rather than upgrade and have a perfectly good main and guide chips tossed out. This is an excellent performing CCD with boosted cooling and water cooling. It eassily holds minus 15 to 20 degrees with no water cooling; water uields about 10 more degrees.
This is the 118 second download version in the unbinned mode. It can be upgraded to the USB version by SBIG. For guided deep sky imaging, the long download isn't so important.
You can view images on my web site to see well this CCD works.
