Finally I decided to install the Astro-Physics AP130 in my observatory as main imaging equipment.
I mounted the following image train:
- CCD camera :SBIG STL-6303 with Adaptive Optic L
- Focuser: I have chosen one of Optec, the TCF-Si.
Early tests indicate the need for a flattener and due to the specifics of my installation I decided to use an flattener from Telescope Service (TS2Flat). This flattener have 43mm of clean aperture and Its screwing directly in the CCD camera 48mm filter housing. For me setup this is very useful. The recommended distance from the flattener to the CCD are 120mm.
