About this product
Part Number: 10222
The Sky-Watcher Explorer 300P DS Newtonian Reflector incorporates the same superb mirror-set as the original Explorer-300P but with two significant advantages: A 1.25"/2" Dual-Speed 10:1 ratio focuser and a slightly shorter tube length for prime-focus photography.
"Detail Explosion: Late into the night we selected the globular cluster M13 from the hand-controller. As it swung into the field of view it was breathtaking, with swarms of stars looking like bees around a honey pot. The view was so good that we noticed a dark feature, commonly known as the Propeller, superimposed on one side of the cluster. It was easily the best view of the cluster we’ve ever had….For crystal clear views of deep space, this is hard to beat!” BBC Sky At Night Magazine

Q1. Is the mirror made from Pyrex glass.
We are often asked this question. Sky-Watcher do not use Pyrex glass for their mirrors.
They used to (many years ago), but they now use an alternate low-expansion glass. There is no change in performance.
Some retailers still mistakenly use the old 'px' (px for Pyrex) product name. We suspect this is what is causing confusion.
