Meade 933 reviews

#933 45-Degree Erect Image Prism (1.25") is rated 5.0 out of 5 by 3.
Rated 5 out of 5 by from Great Accessory for the ETX I use my ETX60 as a solar telescope (with a solar filter) I find the 45 degree much more comfortable to use than the standard port. The 2.4x internal barlow is a plus.I just use my 25mm eyepiece in the standard port to center the sun;then move it to the erect prism to get a magnified image. The erect image prism is well made: I do not see the erect prism line that you would usually see with this type of optical setup. The only con is the focal length change means the eyepiece focus is far between using the standard port and the 45 degree port. Some eyepieces will not be able to focus.

Rated 5 out of 5 by from An essentially great purchase I purchased this product for terrestial viewing and I needed to be very sure that I had left and right correctly orientated. The ETX 80 I put the #933 on has fairly good optics for an inexpensive telescope and the #933 does not seem to degrade them enough to be noticeable. It is a very good product while I only need one I would repurchase if anything should happen to this one. BY

Rated 5 out of 5 by from Left isn't Right anymore! Great for spotting scope use especially with the 45 angle
