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.
This photo apochromat has not only two objective lens (80 mm and 60 mm), but also three accessories (reducer, extender and flattener). Users can choose and adapt accessories according to their needs in focal lengths.
- Two different apertures, many different focal lengths and focal ratios
- With optional star diagonal also very good for visual use
- Dew shield for night use with 80 mm aperture, retractable
- Connections 2" and 1.25", photographically also M54 and M48
- Separate finder shoe
- Vixen standard dovetail bar
- In daytime observing configuration with 60 mm aperture especially light and compact, the smaller focal length allows larger fields of view
