Telescopes (sold or no longer used)
Skywatcher Esprit 100
The Skywatcher Esprit 100 is a triplet apo suitable for full frame cameras. It came with a complete package: finderscope, tube rings, all adapters for photography like an M48 adapter, Canon M48 ring and a special designed field flattner. Unlike the FSQ106 the temperature drift nearly close to none. The first light was in May 2014 imaging the antares region. Many images made with this scope are in my STL11000 gallery. In October 2019 a myFocuserPro1 was added to the scope. I sold my SBIG 11k in 2021.
My new ASI6200 CMOS is a great successor of the SBIG. I sold this perfect scope to a friend.

My first astronomical telescope was a Vixen 90/1000 FH refractor with a Vixen Super Polaris Mount. (broken)
