Explore Scientific 2" Diagonal

The Explore Scientific 2-inch Dielectric-Coated Diagonal Mirror comes complete with 1.25-inch Adapter and dust covers. Solid construction and light weight, this first surface coated diagonal mirror reflects 99% of the light to help maintain the brightest possible image from your telescope.  

The insert barrel is a double taper, so it can be smoothly inserted or withdrawn from the focuser.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 accidentally 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.

Mirror not secured

The diagonal mirror came completely loose just by UPS handling of the package and was getting damaged by flopping around inside the diagonal. I looked inside and found that there was no mechanical mirror holder, just adhesive pads behind the mirror which failed to hold the mirror. I also saw that the mirror was just barely big enough to do the job, which means that the very edge of the mirror is being used for reflections. Not good! I would not recommend this diagonal or any other made the same way (with three screws on each side panel).

Very good quality diagonal

The Explore Scientific diagonal is an excellent quality design. The dual thumbscrews secure even the largest ES 30mm eyepiece. The 99% reflectivity delivers optimal brightness and sharp views.
