    Default Siebert Eyepieces Review & Discussion



    Hi again Hernando. I also would be interested in hearing about your experience with the Siebert 36mm. I've been looking for something in that range to complement my existing eyepieces. I've been seriously considering the Hyperion 36mm because of my experience with the ones I have. One came up recently on AM but I wasn't quick enough. I actually prefer used if the optics are good. I'm more into functionality than asthetics.

    Len, I will receive my Siebert 36mm around the end of the month and will post my impressions on it when I get the chance to put it to use. When I was deciding which 36mm EP to get, I made an extensive research and narrowed it down to either the Siebert 36 Observatory or the Hyperion Aspheirc 36mm, it just so happened the a used Siebert 36 appeared on AM for $100 so I jumped on it and snagged it. Most of my EPs came from the used mart (expect for the BO/TMB's which I got on sale recently for $40 @ at Astronomics) too, there's good value in them as fellow-enthusiasts are usually careful with their astro gear so there are lots of good buys out there, one just have to have the patience to wait for the right one to come along at the right price.

    From what I gather, the Siebert 36 is just slightly a little better well-corrected at the edge compared to the good looking Aspheirc 36 and since you say that functionality takes precedence over aesthetics for you then the Siebert 36 will fit the bill. But from looking over the used mart, the Aspherics look as if they retain original value more than the Sieberts, like Aspherics go for around $150 to $160 whereas the Sieberts from $100 to $125, although both of them start of at retail of $199. Either which way, you can't go wrong with any of these two fine EPs.

    If you haven't seen yet the latest review (Nov/09) about the Aspheric 36mm, look here:

The Siebert 36 may be spartan and industrial in looks (which some people like) but many will attest to it very good performance. A member of this forum has one (Garland - Ebusinesstutor) and I'm sure he'll chime in on his experience with the Siebert 36mm, I don't think you can go wrong with it for you 8SE.

    Hi Hernando,

    Nice to see you in this forum.

    Yes, I love my Siebert 36mm. I am a new stargazer with only a few months experience, but to me it seems to have very clear bright images. I regularly use it as a finder when I am going after new or difficult targets and it is my favorite finder eyepiece.

    However, I use it in my 8" dob (1200mm focal length) and my 80mm ED refractor (600mm focal length). So my magnifications are a lot less than in the 8SE.

    Garland thanks for the inputs! Many are interested in the Siebert 36mm which will make an excellent long focal length combo with the Hyperion zoom, can't wait to get my hands on it (long overseas transit, expected end of the month).

    Thanks for the feedback Hernando. Good info. Another option to consider. If I see the right deal the Siebert sounds pretty good.

    For those interested in the Siebert 36mm Observatory Series (an excellent companion for the Hyperion zoom with its longer focal length), I've finally received it (together with other 2" EPs: Panoptic 27mm, Paragon 40mm, Proxima 31mm, see pic in attached file/s, with Aspheric 31mm & Meade 56mm smooth side still in transit) and had a chance twice to test it out with a WO ZS66SD (also newly arrived) refractor and a C8 SCT. As Garland had earlier said, it is a very good EP giving bright, clear and sharp images which is a definite step up from my old UWA 30mm and GSO 42mm EPs. Comparing the Siebert with with the Panoptic 27 on the f/5.9 WO66, I would say that the Pan is a bit better in terms of sharpness at the edge of field but on-axis the Siebert is able to hold its own and does not loose much to the Pan. In my Nexstar's C8 at f/10 speed, it performs very well indeed which to my eyes, stars are pinpoint sharp to the edge, and it helps that it has a very large eye lens (1-1/2" in diameter - see attached pic) which is easy on the eyes and very comfortable to use (also makes one feel that the $ spent is well worth it). In terms of color correction, it performed better than the Pan27 when tested against the moon's image using the WO66 refractor: moving the moon to the edge of field, I noticed that the moon's limb displayed a slight violet/yellow fringe when using the Pan (same with the Paragon 40mm) while on the Siebert no such aberration was noted. Also, the Siebert did not exhibit pincushioning which was very evident with the Pan and Naglers. With regards to aesthetics, let's just say that it has a very simple design and has this spartan and industrial look which is quite functional, nothing fancy but it gets the job done. Thumbs up for the Siebert 36mm, it's a winner in my book.

    Best,

    Hernando

    Thanks for the followup Hernando. Sounds like a nice eyepiece. I'm definitely going to take a shot at the Siebert when the right deal comes round. I have a nice spot set up for it in my eyepiece case.

    Len, it's my pleasure. The Siebert 36's can be spotted in the used mart every now and then, offered from around a hundred to $125 used; I was lucky enough to snag one at the lower end of $100 (vs retail of $199). Good luck hunting for one!

    Best,

    Hernando
