Apochromatic Refractors
We can offer you a range of very high quality refractors in this category. These include e.g. our two- and three-lens APM Apo instruments, our astrograph series, available as APM or APM-LZOS models. Equipped with Riccardi reducers / correctors or as a high-end version CNC LW II with Feathertouch extracts. All around excellent instruments that should leave no wishes.

- Tube in traditional white - heats up less during the day and is more visible at night
Takahashi offers rotating camera mounts for its telescopes, which are necessary because most of the company's focusers are not rotatable. However, this rotator also makes sense visually, as it allows the ZSP or other accessories to be conveniently rotated into the desired position. The quality is so high that there is no play even when the screw is loosened.
