Back in stock!!

Astronomica have in stock brand new Series 4000 f6.3 focal reducers.

The Series 4000 4-element, multi-coated f/6.3 Focal Reducer threads on to the rear cell of any SCT with standard threads. e.g Meade LX200, Celestron Nexstar etc. It reduces the telescope's focal ratio by a factor of 0.63, so f/10 telescopes are converted to f/6.3; f/6.3 telescopes to f/4 and f8 RCX's to f5.  The 41mm-diameter lens system helps to flatten the field, significantly improving edge-of-field corrections.

It achieves this by reducing the telescope's focal ratio by a factor of 0.33  The 3-element, 41mm clear-aperture optics are multi-coated to maximise light transmission.
