The 180 mm f/9 EDstar differs from the other Fluorostar telescopes offered by TMB Optical (U.S.) & APM (germany). Designed with less expensive glass and an f/9 focal ratio, the scope delivers outstanding visual performance, without the extended color correction which can be obtained in the violet portion of the spectrum using more exotic and expensive optical glass. It is a physically larger scope than many might choose and requires a large mount to support it. Nevertheless, it is still one person manageable, and with five feet of space in a van or SUV, it is not difficult to transport. Since the scope excels at sharp views of low contrast planetary and lunar detail, it does not have to be transported to a dark sky site to perform on

As a confirmed telescope "junkie" and seasoned-observer who has purchased perhaps 150 telescopes over the past 50 years I’ve always come back to the refractor as my very favorite type of instrument. Having owned many sizes and configurations of the breed, I’ve been on a seemingly endless quest for the ideal balance of

The package includes a 6" f/6.5 tube assembly (about 21 lbs.) with a cradle that has a handle, a 2" diagonal, a wide-field 20mm (1.25") eyepiece, a 8x50mm finder, and a very nice metal case for transporting the scope.

As an astrophotographer I wanted a refractor rather than a reflector since besides imaging from my own home observatory I do a lot of traveling to star parties and I wanted to eliminate the issue of collimation.

The TMB 175 is an apochromatic refracting telescope that utilizes an air spaced triplet objective lens designed by Thomas Back. The lens and cell are manufactured to TMB Optical standards by LZOS in the Ukraine, which are then installed by TMB Optical in CNC machined tubes manufactured by APM Telescopes (Saarbruecken, Germany)

The scope, mount, accessories, camping gear etc.. all fit in my compact Subaru Forester. I get a kick when I pull up to the registration desk at a Star Party and when asked what scope did I bring I usually get a “yeah right” look when I respond with “10 inch refractor” as the individual looks at the compact Subaru.

You really want to know how the Neo-Achromat optics performed, eh? With all of the hype around high-end APO scopes, and the soaring prices, everyone wants to find reasonable substitutes. Even used APO scopes command unearthly prices.

First it is big setup next to my 120mm Skywatcher. As for the optics I can tell you that the optics in this one are very good, slightly better than my 120mm only because the 120 has a tad of astigmatism. Otherwise the 120mm is very well corrected. The 150mm has a slight undercorection which is about the norm for Syntas as most are undercorrected and few are over.

This is a review and comparison of two of the larger and better currently available "APO" refractors. There are others that can be ordered, such as the Meade 6 and 7" APOs, but they have not fared well when viewed by others and do not command the respect of these two telescopes. The TMB refractors are coming on line, but only a handful of the 6" and larger TMB scopes are in this country, and none are currently available for testing. That leaves these two 6" APOs as the 'top of the heap' in refractors one is apt to encounter for sale, or to view at a star party. They are, in addition, both remarkably alike yet quite distinct at the same time.
