fussy re eye-position, and too many seagulls). It is also more user-friendly than my 40mm Axiom, due to smaller size and less out-travel.

How does the sharpness/brightness/contrast/color compare to the Axiom?

can not say at this stage, as i need more time at the EP. Also, although the Siebert and Axiom are both stated as 70deg AFOV, the different focal lengths tend to make direct comparisons difficult.
For me, the Siebert has two obvious plusses over the Axiom

1) Siebert EP has the stars are in focus almost to the edge. The Axiom tends to smear the stars in the outer 10-15%.
2) Siebert is shorter by more than an inch, and much lighter (from memory, about 12oz versus 1lb3oz). This is important in a Discovery scope as they are bit top-heavy.

Sorry i could not be more specific (still dealing with a personal health emergency)

>Piece of junk! This thing is assembled from reject optics in a crudely home-made EP body. "Observatory Class" is certainly a rather wild name for this reject from a kid's toybox.


I am sorry you had this problem with the eyepiece. If you would like please contact me and I will either replace or refund you.

What a coward you are! Put your name on this!

I bet you have never even held one of these fine eyepieces in your hand.

You are a joke.

>Awesome and flawless eyepiece. NO kidney bean noticed by me in an f/4 and f/4.9 Newt. Sharp, non-distorted images, with excellent color. Generous eye relief good for "visitors" and eyeglass wearers. Price about $200 is fair for this level of quality.

JULY 2006 UPDATE: A few months ago I encountered Harry Siebert and his wife at North Carolina's TriStar astronomy gathering. I mentioned that I had one of his early versions of the wonderful 36mm eyepiece. He volunteered to upgrade it to his latest specifications FOR FREE. And that he did. While he was outside showing attendees the sun through a solar scope, I spoke with his wife, who told me that Harry is obsessed with giving all his customers the finest experience. What more could you ask of an eyepiece manufacturer?

By the way, I am not an anonymous brick thrower. Check out my award winning astronomy links web site: http://astronomy-links.com (keep the hyphen). Clear skies.
