TMB Optical 180 F/9 EDstar APO Refractor

Mar 21 2005 12:05 PM | Guest in 140mm + Refractors

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

Astro Telescopes 152mm, f/5.9 Refractor OTA

Dec 17 2009 08:35 AM | Larry Carlino in 140mm + Refractors

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

A&M 152mm f8 APO Refractor

Nov 07 2006 07:55 AM | Bob Berta in 140mm + Refractors

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.

Celestron's C6-RGT Refractor

When such a large refractor is coupled with a computerized mount, it becomes an even more desirable telescope.

"Big Eye" TEC/APM 10" F6.6 Achromatic Refractor

Mar 29 2005 07:41 AM | TPMack in 140mm + Refractors

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.

Vixen NA 140 Neo-Achromat OTA

Mar 29 2005 07:48 AM | Eddgie in 140mm + Refractors

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.

Synta 150mm Achromat

Mar 28 2005 08:48 AM | Guest in 140mm + Refractors

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.

Astro-Physics 155 F/7 Starfire EDFS APO Refractor vs. Takahashi FS 152 F/8 APO Refractor

Mar 28 2005 11:31 AM | Dave Novoselsky in 140mm + Refractors

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.
