Harry Siebert Optics Premium 9mm, 2 inch
Really poor eyepiece. Laughable to be compared as "rivaling a Pentax". Suffers from internal reflections, and has poor contrast. Mine also suffered from coma to almost 40% in an f/6 dob. My Pentax eyepieces walk circles around this junker.

As with the other poster, Harry refused to refund my money. He is a swindler. I suspect the glowing reviews here are planted by Harry, since they certainly can't be true accounts of the performance of this eyepiece.

Are you a bot or a real human? This looks just like any troll I have ever come across.

Strange that only people who appear to intensely dislike Siebert's EPs are the only ones that can't get their money back.  Hmmm.  Strange indeed.  Although the person who posted this appears to know what he/she is talking about, it's still clear that this is a hired basher.

I have a CGE 14" and two sets of binoviewers, a 1.25" set and a 2" set, both by Siebert.  For the 1.25" binos I have two pairs of Plossls, 40s and 36s, both high quality, a pair of Naglers, a pair of 18 mm Ultimas, and a pair of Siebert's 24s.  The only EPs that are better than the Sieberts across all criteria are the Naglers (slightly better contrast and little or no ghosting).  The ghosting issue on the Siebert 24s is handled nicely by the Skylight Filter that came with my scope, and is only present on the very brightest objects (i.e., Saturn, Sirius).  It's a $30 part. Of my fairly considerable kit of EPs, the Sieberts get the most use by far in the 1.25", and the Naglers (my 2" set) get the most use in my 2" binos, although the Siebert 34s in my 2" binos are easier to use, and get used almost as often as the Naglers.

When I think about it, though, last night, using the 1.25" binos and the Siebert 24s without the Skylight Filter, there was no ghosting at all on anything, including Saturn, Sirius, Aldabaran, Rigel or (which was most spectacular!) The Hyades.  Hm.  I'll have to think about that one.  It's also worth mentioning that some of my friends who view with me prefer the Sieberts over the Naglers on more than a few objects, so of course it's, as usual, a matter of personal preference.  One guy's point is that the Naglers, in making a darker backfield, also reduce light, and he may have a point there.

You coward, Why not put your name on this. 

Everyone knows that Siebert has the best money back guaranty around. That is why you cannot sign your review.

The negative comments made about this eyepiece must have either come from a personal antagonist of Harry Siebert or are the result of an individually bad or damaged unit.
This is my first Siebert product and I was very pleased with both the workmanship and fine performance of the eyepiece.
I found it to be extremely sharp in my 4.9 reflector....views of the Moon were notable for that sharpness as well as the very wide field of view...you CAN, as siebert says, actually get the whole Moon in the FOV of this 9mm at one time.
I have also now decided to purchase a couple of his high power 1.25" models.
I expect they will be just as good.
Much value for your dollars here.

Whoever this person is, he or she is bouncing from one product to the next, posting the same thing.  Let's just examine the facts: If you buy a Siebert EP or any other product and it arrives in substandard or faulty condition, or becomes faulty within the 60 day money-back period, he'll replace it or refund your money.  It's just that simple.

Let's DO get real here (you can kinda tell that the "reviewer" is, well, a neuron or two short of a completed synapse).

Fell apart in your hand? I do not believe you ever had a Sieberts eyepiece in your hand.

More than worth the money-less than half what a Nagler or Meade UWA is used.

The only good thing about this eyepiece is the fact that it has a money back guarantee!

After reading the wide variety of opinions about this vendors products, I was somewhat hesitant to make a purchase.
I needn't have been.
This is a very fine eyepiece across the board, and I intend to purchase others from Seibert as time goes on.
The price difference between these and the "supers" (Televue, Pentax, Etc.) is significant, and the quality of views is not that much different.
It is sad to see the obvious bashing that is evident in some posts here....makes you wonder why anyone would take the time to be so vindictive, unless a personal problem is involved.
I an very satisfied with this purchase.
