Our Observatory Class Apochromatic Refractors are defined as such because their size makes them impractical for normal transportation. The optical quality of our Observatory Class is just as perfect and colour free as our smaller designs.

Our Observatory Class all use LZOS produced optics and are custom made to order for our clients. This permits clients to specify custom mountings, focusers and also additional balance weights due to the front heavy nature of the designs. We quote a 24 month lead time for all our Observatory APO’s due to the time it takes to manufacture optics of such large size and performance.

The APM APO Observatory Range comprises the largest Apochromatic Refractors available in the world today, culminating in our Massimo Riccardi designed 510mm aperture 6500mm focal length Super APO.

When a client chooses one of our Observatory APO’s we not only discuss the detail of the telescope design but also the mounting and installation requirements which we handle directly.

Our Observatory Range currently comprises the following models

228 / 2050 CNC-II

254 / 2250 CNC-II

280 / 2500 CNC-II

304 / 2280 CNC-II

304 / 3600 CNC-II

330 / 3960 CNC-II

356 / 4270 CNC-II

510 / 6500 CNC
