In addition to the world-leading focusers from Starlight Instruments, which are known for their best quality, we also want to offer our customers alternatives that are reasonably priced.
Our currently largest model, the APM 3.7 "focuser with rack and pinion drive and 1:10 reduction, remains stable even under high loads and is ideally suited for photography. Our APM focusers are also of very high quality, but are much easier on the wallet! The connection dimensions are based on the Starlights models, so an exchange and later upgrade is possible without any problems.
On the accessories side, there are multiple connection threads for universal adaptation. Our focusers are also technically advanced with microfocusing, the possibility of rotation and the use of stable construction features. Even heavy accessories are moved precisely, safely and reproducibly. This focuser is ideal for visual and photographic use!
The generously dimensioned extension enables absolutely vignetting-free photography with full-format sensors. As an innovation, the focuser is now also equipped with the new APM 2 "Fast Lock.
