      Comments:

      This does exactly as described. I did find, however, that it was les than ideal for astronomical use. I wanted a right view for public night and it worked just fine. Perhaps out of long habit, I felt the conventional 90 degree was more comfortable. For daytime use though, can't beat it.

      1.0 Low quality...only for daytime use.

      Pros:

      Free with scope

      Cons:

      Poor quality housing, bad coatings on occasion

      Comments:

      This is a very low quality prism that is really suited for daytime use only. Some of these cheap 45-degree prisms even say that in the instructions...only good for daytime use.

      They do okay in daylight, but you can get better quality prisms, although you would have to pay for it. These cheap prisms usually come with a scope, so at least it is free. The fit and finish of the housing is also not that good, but again...it's usually free with a scope. Some of these also have poor coatings, but since they are mainly for daylight use, this is not much of a problem. I would not purchase one brand new...get a used one if you want to do daytime viewing.

      Remember...don't buy one of these new! It's a waste of money.

      2.0 Celestron 45° image erecting diagonal for 1.25”

      Pros:

      Nicely made, Typical Celestron finish

      Cons:

      Vignettes, seems to add CA in a small Achro, comparitively poor image quality

      Comments:

      I received a Celestron 45° Erect Image Diagonal as part of a trade deal a few weeks ago. After using it a few time I understand why the other guy so readily threw it in as part of the trade. IMHO this diagonal is of about the same quality as the $50.00 Big Box Store telescope eyepieces. I don't think I've ever seen a diagonal that appears to mildly increase fringe in an 80mm Achromat before. With a wide angle eyepiece like a Nagler it slightly darkens the corners indicating it's not quite large enough to prevent vignetting. If you’re looking for something to occasionally use during the day to look at things through a small scope, this diagonal does have the advantage of being an erecting diagonal. It is basically well made. If it cost $20 or $25 I wouldn't be all that upset but at $40+ I certainly would not be enthralled with it's performance.
