The mirror in this 1.25" Orion Enhanced Star Diagonal has been meticulously polished and features enhanced aluminum coatings to yield excellent 97% reflectivity. It fits 1.25" focusers and accepts 1.25" eyepieces. Ideal for refractor telescopes.
Very fine quality product to give the crisp view of all the celestial objects within the resolution of my 80mm refractor. I was not aware the image would be reversed. That was a shock to see Pleiades reoriented. That is my only disappointment. I wanted the extra quality reflectivity if it only had the correct image orientation.
Favorite object to observe: M-42, M-45 and Double Cluster
This solar filter fits the Orion StarMax, Apex 90, and Meade ETX-90. The 4.10" Orion Full Aperture Solar Filter is a must for safely viewing or photographing the sun's surface. Provides more contrast and more natural color than Mylar filters.
Years ago my practice to view the Sun was to hold a white card before the eyepiece and focus the image projected. Worked fine but I noticed the mirror diagonal is now scorched a bit with a haze. I determined then the only safe way to view the Sun is with a proper solar filter. This filter is excellent in fit and finish and am glad it is a glass filter than a plastic film type. The included foam shims a nice means to insure a snug and non marring fit. I have the Orion EZ Finder Deluxe finder and am glad for the hood it includes to insure the sun is not a hazard there. The Sun is clearly visible with sunspots in full detail. The only other valued accessory would be a narrowband hydrogen-alpha filter.
