APM Telescopes

The APM 203mm Triplet is available in two different focal lengths. The 1420mm F7 version is for those seeking a higher focal ratio for imaging.  The 1420mm is made to our customary high standards with lenses guaranteed to a minimum 95% strehl and with superb colour correction. Customers have options on dew-shield, back focus and even paint finish specifications as all 203mm Telescopes are made to order.

Despite its large size the 203mm series Apo__s may still be considered portable although admittedly at 28 and 31kg for the two models you will need to be feeling strong and have a suitably capable mount! The 203__s may be further enhanced through use of a Thomas M Back designed medium format field flattener and a Massimo Riccardi Designed triplet Apo reducer flattener. The latter converts each model to a 1065mm focal length F5.25 and a 1350mm focal length F6.65 telescope with an image circle up to 50mm.

Both scopes feature exceptional optical performance (see the 203/1420 colour correction chart below) enhanced with multi baffled and anti dew Kruppax tubes fitted with the outstanding Starlight Instruments 3.5_ Feather touch focuser which can be motorised.
