Home Accessories Diagonals Telescope Diagonals For Astronomy Explore Scientific Diagonal 2 Inch Dielectric
The Explore Scientific 2-inch dielectric coated diagonal mirror comes complete with 1.25-inch adapter and dust covers allowing both 2 inch and 1.25 inch eyepiecees to be used. Solid construction, attractive quality finish and light weight, this first suface coated diagonal mirror reflects 99% of the light to help maintain the brightest possible image from your telescope. Dielectric coatings are durable allowing the surface to be cleaned if ever required and the reflectivity does not diminish over time with oxidation that occurs in alluminised coatings.Delivery is normally around 3-5 business days on this product.
The insert barrel is a double taper, so it can be smoothly inserted or withdrawn from the focuser. The wide part of the taper prevents the diagonal from accidently falling out of the focuser if the set screw loosens up. Eyepieces are secured in the diagonal with a compression ring lock on both the two-inch eyepiece holder and the 1.25-inch eyepiece holder.Each 2-inch Dielectric-Coated Diagonal Mirror is serial numbered assuring excellent quality control
Nice Premium ‘Apple Like’ feel to this diagonal, well constructed and solid piece. Fits nicely with the Baader CkickLock collar too. Great service from Harrisons. (22/08/2020) Gary Robertson - Anglesey
