Dave Says: "The GT81 is a tried and trusted 3 element design with excellent colour correction, and this one has now been brought up to date, with a new R&P focuser and is a great all-round 'scope."

"I've had my own WO Megrez 72FD for 7 years and its still my most used APO, and this is its logical upgrade. With the same bomb-proof build quality and now brought up to date with a precision rack and pinion focuser making it ideal for portable astro-photography."

The stunning new 2018 GT81 three-element super APO is the new jewel of the apochromatic refractor world and offers superb quality for imaging and visual use at an affordable price!From the pristine white finish on the CNC to the elegant gold, red or blue trim which has more than just good looks...

The New GT81 features a 3-element objective using high-quality FPL-53 extra-low dispersion glass that reduces any secondary spectrum to an unbelievable degree.

Add a Flattener 0.8x (6-GT81) for just £149 extra
