The finest optics we can achieve by the hands of our skilled opticians
No full aperture corrector plates at the open tube end. On a large aperture, doomed to dew and totally disrupted images. Sub aperture corrector plate allows cooling and stabilising of image up to 5 times faster than closed tube designs.
Four vane Spider is made from solid aluminium to give ultimate strength and total collimation stability making this an Incredibly robust system which consistently maintains collimation.
Fixed primary. Means that mirror rock and image shift on competing traditional designs, especially SCT's, gone forever, guaranteed.
280mm back focal length. Enough for virtually any accessory considered. Even if you have a non standard accessory, the secondary support allows easy movement to adjust precisely the focal plane position you choose.
Optical back is suited to standard SCT threaded accessories.
Diffraction limited for 10mm field, maximum of 40 micron spot size at 20mm field. Basically, incredible in visual observing and also, gives outstanding CCD image quality with some of the largest CCD chips available. We combined the 'wish lists' of many world renowned and respected CCD users and, designed many of the telescopes parameters around their comments.
Full length dovetail plate on tube to suit standard size dovetail receivers. Larger dovetails available.
Collimation mechanics 'fool proof'
