Stellarvue 2" Dielectric Star Diagonal
|Stellarvue's latest diagonal uses a thick, over-sized mirror polished to 1/10th wave with dielectric coatings producing 99% reflectivity. Unlike most star diagonals, it features a collet style twist lock for securing 2-inch eyepieces. It also includes a 1.25" eyepiece adapter that is fitted with the more traditional brass compression ring for securing the eyepiece. Both the 2-inch nosepiece and the 1.25" adapter are threaded for filters. |
Should the mirror ever need cleaning, simply remove the two side panels using a 2 mm Allen wrench and pull off the carbon fiber side plates. Pushing on one side of the mirror will cause it to slide out the other side. Once removed, the mirror may be cleaned in the same way you would clean any other optical surface. It is strongly recommended that the surface be brushed with a camel hair brush, such as those found on a lens pen or a photographic squeeze bulb and brush. Stellarvue recommends using acetone and a microfiber lens cloth, but we don't normally resort to acetone without first trying a mixture of isopropyl alcohol and water. Keep in mind that acetone dissolves paints and plastics, so you need to be careful where you use it.
