Thank you all for your help. It’s much clearer when you can see the parts fitted together. I have now obtained a couple of product pdfs from Baader which have a lot of information in them to read. I am thinking of first getting set up with the Baader T2 system for use with existing eyepieces as it seems a more secure system, and then adding the binoviewer when funds permit.

Stu Thanks for your comments and recommendations on star diagonals. Pictures of the quick change set up would help as I would like to go down that route. Presumably I could then use the baader T2 instead of my existing 1.25 star diagonal as part of my routine set up. Does the quick change add significantly to the overall length of the prime focus?

Hi Can someone on the forum give me some practical advice please? I am thinking of buying the new Baader Maaxbright Mark ii binoviewers. I intend to use them with both my existing telescopes. One is a TAK Mewlon 210, and the other is a TAK TSA 120. I have the following questions which I a most hoping someone who already has the same set up can answer. 1) Apart from the Binoviewer what connectors and star diagonal would I need for each scope? Can you advise exactly which connectors and what purpose they serve so that I can understand item by item what is needed? 2) For the Mewlon will I need a glass path corrector to bring the telescope to focus, if so which one would you recommend? 3) For the TSA 120 I assume I will need a glass path corrector. If this is the case which would be recommended? 4) The binoviewer comes with a T2 connector thread and with a mini bayonet. What is the difference, and what are the advantages of each? 5) I would prefer if during an observing session I could revert occasionally back to a single eyepiece. Will this be easy to do, and do I need any further parts for this without disassembling things. I would like to be able to do this easily. The plan is to use with TV panoptic eyepieces, 19 or 24 mm as I already have one of each. But advice on eyepieces would also be welcome. I am sorry if the advice sought is very specific, but having bought the Williams optics binoviewers some time ago, I found that there were difficulties especially with the Mewlon in getting a satisfactory magnification, and that it was difficult to obtain a good, sharp merged image and comfortable viewing position. I came to the conclusion that converting to a T2 system would be a good solution, and so I sold the Williams, but didn’t really want to spend the money on the Baader Mark Vs. It looks as if the BM 11 have superior eyepiece holding, and that the T2 system will shorten the lighttrain, but I want to be sure of what I need before I buy, if possible. I would really appreciate specific guidance from an experienced astronomer who has the same equipment. Thanks David
