A new product coming out around Q2 2016.

Fast focal length Newtonian of larger apertures can suffer from rigidity problems which affect collimation due to the weight of the mirrors. What's more, tube currents often affect large Newtonian telescopes, especially those with solid tubes.

We have customers who like the idea of large aperture Newtonian imaging, yet are frustrated with the "reasonably priced aperture gap" in the fast-astrograph market. This product is designed with these customers in mind.

So, if you want a faster focal ratio Newtonian which can be mounted on a GOTO EQ mount for wide field imaging of both planets and deep sky objects, plus visual observing, then this could be the right scope for you.

Design objectives:

1) A scope which is more rigid than a carbon fibre or metal tube, in order to maintain collimation. A triangulated truss and strut design achieves this objective.

2) An open tube design to encourage maximum air flow, reducing tube currents to negligible levels, and allowing fast cool-down. Air flows through the shroud which covers the truss tube assembly, but dust light and dew are not a problem.

3) To reduce the effects of expansion and contraction caused by temperature change. Carbon fibre has a very low coefficient of expansion, and is the perfect material for the job.

5) Large aperture optics with perfect colour correction, allowing maximum field illumination and fast focal ratio for imaging. A fast Newtonian is the answer.

Specification:

Sorry it's taken so long. There have been a few stops and starts along the way, but they tend to make for a better product in the long run.
