The FTF3035B-A is a superbly made and ultra smooth rack and pinion focuser. It is typically fitted to Refractor telescopes. Typically the FTF3035 is used for Astrophotography applications where its smoothness, high load capacity of up to 7kg and resistance to tilt are of benefit.
It has a draw tube travel of 3.5" (88.9 mm) which does not suffer from tilt thanks to its plain bearing mounting using a combination stainless steel and Teflon. The FTF3035 has a fully baffled draw tube and can easily illuminate full-frame sensors.
Please note that the FTF3035 is NOT supplied with a 2" clamp as shown in the image above. This is an optional accessory which can be found HERE. As the FTF3035 is often used for Astrophotography, it is more common to use a draw tube adapter to allow the direct fitting of a corrector. For details of adapters to fit a specific corrector, please contact us directly.
The FTF3035 is also NOT supplied with an OTA mounting adapter. These can be found HERE.
