CA300
The acronym CA300 stands for Carbon Astrograph 300mm. It is a homemade Newton Teleskope dedicated for astrophotography.

NON1000
In the field I use my NON1000 Telescope. Structure, Diagonal and OAZ are from a Lacerta 200/1000 Newton. Mirror was replaced with a GSO 200/1000mm.
BA200
It is an extremly fast Newton telescope, optimized for photographic use. BA200 is a acronym for “Boren-Simon Astrograph 200mm”, because it has the same optical system design as the famos commercial 8″ Boren-Simon Newton. The primary goal was to built a scope for narrowband imaging. My dream was to finish an object per night. The telescope is normally used with my Moravian G2-8300 CCD camera. First light was in June 2012 shooting M13.
After initial difficulties this scope has been a great success. At this point I have decided to let it imaging unattended in my garden. During the night, temperature drift was not a problem, but filter change required refocusing and I had to get up from bed. A motorfocus and autofocus stands on my wishlist. I tried Robert Browns myFocuserPro and this was the begin of a great DIY success story. Today, all of my three photographic newton telescopes have this motorfocus. Robert Browns design and software works stable and reliable and it is very well documentated.

Esprit100 with SBIG STL11000
The Skywatcher Esprit 100 is a triplet apo suitable for full frame cameras. It was my new optic for the SBIG STL11000 and my Canon 6D and finally the sucessor of the Pentax75. 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 myFocuserPro2 was added to the scope.
