Description

  • High quality optical Prism inside rather than a mirror which makes your image clear and sharp.
  • More comfortable viewing orientation as you observe from above, filter thread for any 1.25" filter. Accepts standard 1.25" eyepieces.
  • Protective coating on the mirror to ensure a long life, metal barrel - for secure seating in the focuser.
  • This is a great diagonal for daytime terrestrial use and night time astronomy applications for telescopes or spotting scopes.
  • 1.25" 45-degree mirror star diagonal for refractor telescopes with 1.25" connector (not recommended for reflectors).

Customer Reviews

Works very will and allows me to use my existing ...Works very will and allows me to use my existing 2" eyepieces for terrestrial viewing. Seems quite well made. Not something I'd use on astronomical objects but works well for terrestrial views and the moon.5A good productVery happy with this item. Well made and sturdy. Image is correctly oriented as advertised. I had returned a different one because while the image was right side up it was still mirrored. The insert for he eyepiece is a bit shallow but it is made of machined metal instead of plastic like many other diagonals.5Very happy about this purchase, a worthy and necessary upgrade.When I received this 90 Astromania star diagonal it weighed twice as much as my original part. The eyepiece holder is machined aluminum that screws into a hard ABS plastic body and a anodized aluminum barrel with filter threads. In conclusion, this is a worthy and necessary upgrade if your star diagonal is of an inferior manufacturing process.5Great for a backup prismThe set screws do not engage smoothly. Depending on orientation it wants to tip over on it own even when the set screws are as tight as possible.4Works Well EnoughIt works well enough but isn't made of the most durable materials. It does correct the inverted image just as was expected and is clear enough for my uses.4Happy Camper!I tried to find a used WO, Astromania, etc. 2", 45 degree erecting prism diagonal for several weeks. Thought I'd found a used on via Astromart, but it turned out to be, lets say, not in the condition I wanted for my collection, and he wanted $145 for it! Not! Kept looking, and came across this Astromania unit being marketed thru Amazon. To my eyes, it looks exactly like a William Optics unit, and the build quality is excellent. I immediately took the eyepiece and tried viewing several nearby terrestrial objects through my TV-85, and I was pleased! The "kicker" to all this is that I bought the diagonal new for just $15 more than the extremely well-used unit offered thru the Astromart website! I highly recommend you try this out. You'll be impressed!5false advertised. Nose piece is paint on.The one that arrived was not this one. Should be able to removeboth nosel, and nose piece. For cleaning purposes, both nosel and nose should be removable. But nose piece is painted on. I am shocked at Atsromania for this product. It should've been basically a generic of the Celestron version.1One Star Eyepiece barrels hit the prism if you have a filter screwed into the eyepiece barrel. 1Good basic diagonal.When I picked it up I was impressed at its weight. It has a very solid feel. The mirror is very clean, and when I installed the diagonal in my scope and tested it out on some distant trees I could focus clearly, no distortion. The thumbscrews on the eyepiece receiver are big and easy to grip. The plastic on the receiver tube seems a little thin, and it makes me kind of nervous about stripping the screw holes, but only gentle pressure is necessary to hold the eyepiece securely in place. All in all, it is a good basic diagonal. Looking forward to the next clear night.4Love the Quality and Performance for the Price PointMy wife was given a starter telescope for her birthday that came with cheap starter accessories. Among them was a cheap Erect Image 90 Diagonal that was just a mirror. This Erect Image 45 Diagonal Prism gives a much crisper image, has the correct orientation to what you see with the naked eye and the angle is more comfortable for viewing. I have a moon filter for viewing the full moon without it being too bright, and (after testing) I'm able to thread it onto this prism which was a huge selling point for me. I have tested all connections and combinations of my accessories including my 5x Barlow, which clears the receiving end without getting close to the prism. I love what I've seen so far from this prism and recommend it to any fellow amateur astronomy fan.5Nice Diagonal for the Price+>Very nice upgrade from the 1.25" Celestron diagonal that I was using. Huge difference in brightness, fov, and clarity.>Easily gets at least 150x from a 4" refractor. Bands of Jupiter, defined rings around Saturn, better double star separation and glob clusters, etc.>Edge to edge clarity with no noticeable distortions or abberations.>Sturdy and feels solidly built.>Adapter ring included. Good thumbscrews.>Price.->Fogs up when the humidity is higher than 60-70%. Removing the eyepiece and letting it breath for a few seconds usually clears it up though.5
