6 elements fluorite apochromatic refractor, 55mm f3.6.
Borg fluorite apochromatic refractor 55FL f3.6 with ESATTO 2" has 6-element fluorite optical design that generates images without false colors, contrasted and rich in details. Optimal back focus is 60mm from M57x0.75 female thread on the back of the focuser. The short focal length (200mm) and the fast focal ratio (3.6) make it ideal for shooting wide field extended objects.
ESATTO 2" robotic focuser
Often refractors are provided with focusers suitable only for visual use but not for imaging. In fact, during long exposures required in deep-sky astrophotography, you have to keep the sensor perfectly in the focus point avoiding focuser that moves camera sensor out of focus. For this reason Borg fluorite apochromatic refractor 55FL f3.6 comes with ESATTO 2" microfocuser that offers high load capacity and great focusing precision! The focuser has a rear M57 thread to connect cameras by adding the proper photographic adapter.
Borg fluorite apochromatic refractor 55FL f3.6 with ESATTO 2" with the following optional accessories: 240mm PLUS Vixen type dovetail bar installed below the telescope, EAGLE CORE with CompactGuide 60mm guide scope above the telescope.
PLUS support rings, already compatible with EAGLE:
Forget about the uncomfortable and weak support rings that are often found in cheap telescopes! Borg fluorite apochromatic refractor 55FL f3.6 with ESATTO 2" comes with our PLUS (Prima Luce Universal System) rings, aluminum, made with high precision CNC machines. This gives you maximum freedom in connecting other mechanical accessories (dovetail plates, guide rings, dovetail clamps) always with simple M6 screws and with 2 screws for every element (to avoid flexures). This way you can also connect the EAGLE directory on the telescope creating a fantastic system for astrophotography that does not require external computers control all your system!
The most compact and lightweight astrograph
Borg fluorite apochromatic refractor 55FL f3.6 with ESATTO 2" microfocuser is the most compact astrograph ever! When the focuser drawtube is extracted to reach focus position, this telescope is only 20cm long so it's really easy to transport. And thanks to a weight of only 2 kg, the Borg 55FL f3.6 with ESATTO 2" is the perfect companion for your travel astrophotography!
