We received a question from our customer about our turn-key telescope solutions. It was actually only a short question, but we answer it in detail to show you what kind of benefit it provides, when ordering a complete telescope system from us.
Could you tell me what the OTA rings on the TEC140 in the attached image (from a Baader installation) are. I can see that the outer rings are the Baader heavy duty rings but what out the inner rings (inside the larger, outer rings). Do you sell these inner rings?
In short: Unfortunately we cannot offer these as regular purchasable products.
In detail: these inner rings are always specially made for each complete telescope project where we supply all instrumentation ourselves. Only in this case we have the telescopes all in house for combining, can measure the EXACT tube diameters and fabricate matching contact-pressure rings, to stiffen out the tube(s), so that there is no chance at all that the tube itself is getting deformed from the three pressure pins of the outer heavy duty guiding rings.
Such precaution is mandatory if the owner wants to do unguided imaging, since otherwise the tube will get...
The "Telescope Engeneering Company" has long earned a reputation as a top-class telescope manufacturer. The family business in the US state of Colorado has been manufacturing telescopes of the highest quality in small series since the 1990s.
Before TEC manufactured the first refractors in the year 2000 (regular production of APO140 started in 2002), TEC were offering Sitall mirror sets from LOMO (upto 1.4m) and MAKs from 150mm to 300mm. The distribution of these products is stopped.
The three Petrunins are based on class instead of mass, therefore the delivery times are long! But the quality is also outstanding: TEC is one of the few manufacturers in the world that still masters durable oil-spaced triplet lenses. This results in particularly robust and stable optics that cool down very quickly and effectively. During the 15 years that Baader Planetarium has been importing TEC telescopes to Europe, only one oil-spaced lenses had to be renewed. We can therefore vouch for the quality and long-term stability of this oil-spaced lenses. Read more about the advantages of oil-spaced lenses for apochromatic triplet objective.
In years of work, TEC has now succeeded in manufacturing all device classes with a genuine Fluorite as a middle element. In...
Mounting accessories connect telescope and mount - be it for a permanent setup or to make quick changes from one instrument to the next possible. We can offer several bars and plates, so that you can adapt almost every telescope:
Modell V (EQ) bars and clamps - for Vixen / Celestron / Sky-Watcher / Synta and many more. (Base width of the bar's prism: 44 mm. Bar width of the side facing the telescope: 70 mm)
Modell Z bars and clamps - for Zeiss / Astro Physics (Base width of the bar's prism: 40 mm. Bar width of the side facing the telescope: 70 mm)
Modell 3" bars and clamps - for Losmandy / Astro Physics (large) / Celestron (large) (Base width of the bar's prism: 76 mm, equals 3". Bar width of the side facing the telescope: 105 mm)
Special lengths up to 6.000 mm long V, Z and 3" bars
The matching accessories
All of our dovetail bars do have integrated, deepened marking lines over the whole length of the bar. They mark the exact center line of the bar, as well as the seperation of the screw holes of Celestron telescopes and Astro-Physics mounting rings, so that you can easily drill...
Our company exists now for more than 50 years. In this time, more than 15.000 Baader Planetariums (the first patented product of our company) help all over the world to give students an understanding of astronomical correlations. In our own manufactory, more than 500 observatory domes have been produced and delivered turnkey-ready. Instruments and telescope accessories from "Baader" are known for their high qualities by many astronomers and universities. We consider it our duty and obligation, not only to sell telescopes, but an indivdually selected telescope system, that brings you a lifetime of joy.
