4.0 out of 5 stars Guide, measure angle of arc, and Az in one EP, January 23, 2011

A very virsitle EP. Lots of fun for helping take better observation notes. Calculte size and distances with the EP. Can be used for drift alignments, but I prefer a simpler double cross hair EP for this.
The illuminator works fine, but is not a pulse type, though it can be screwed off and a pulse used instead. Optics are simple good old Meade EP optics, but then you use this EP for measurements more than observing fine details.
You will need to do a little math to measure the diameters of craters or distances with this EP. It can also measure the separation in minutes and seconds of double stars. Using the protractor built into this EP you can align it to measure angles (Az) from target to target, and with the linear scale distances. (you need to do the math based on the scope you are using the EP in). Has a very small double cross hair reticle in it also. So it can be used for drift aligning your mount too, or if you have the patience manual guiding. The EP does barlow well, with all of my 1.8X, 2X and 3X barlows.
This is not the EP you want for lining up you alignment stars for a Go-To scope, nor for manual guiding. The simpler double cross haired illuminated EP is used for that. It is a fun EP to play with, and can help you take much better observation notes.

For centering a star, collimating, determining angular distance, you won't find an eyepiece as effective for the price!

2.0 out of 5 stars Sometimes a bit flaky!, December 1, 2011

I was pleased with the lens when I first got it and it worked wonderfully. Then, within a couple of months, it started 'flaking out' on me. Sometimes it would illuminate and sometimes it wouldn't. I thought it was a battery problem, but it wasn't... it was just flaky! For what Meade charges for this lens, I wish I had looked a little further and found a better quality eyepiece. Oh well, that is the state of products on the market today, I guess. I gave it a 2 stars because it worked for a couple of months, if it operated when I got it like it does now, I would have given it 1 star and sent it back. You decide.
