The ultimate specification for a diagonal with a quartz mirror, precision aluminum housing and 99% reflectivity dielectric coatings. This premium accessory is an ideal upgrade for any telescope that can utilise a 1.25" diagonal ensuring perfect alignment at 90 degrees and maximum light transmission. The durable dielectric coatings not only boast 99% light transmission but do not degrade like ordinary coatings and can be cleaned if required.
At such a low price for a high specification this diagonal really is a remarkable bargain and can enhance the performance of any telescope that can utilise a 1.25" diagonal, recommended for any high quality telescopes.
Great service and prompt delivery from Harrisons . Revelation diagonal is an upgrade for my existing one and it doesn't disappoint. I would recommend this product and Harrisons. (08/12/2017) David - FIFE
