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...
