thank you, thank you.

You think you know all you need to know and then you read this and learn a lot more. I feel more confident that my scope is collimated more precisely.

Really great. Thanks again. :bow:

That link is almost 9 years old, so it would be in archives now. Try this one Secondary Mirror Alignment

Years ago, I published this article here
https://www.cloudyni...telescope-r2881
I speak because I built a lot of binoculars, even unusual constructions, but this one is unbeatable in its performance, can withstand huge magnifications, the color defect is minimal and there is no other optical telescope, not even a super APO refractor that would show better.
The best test for any telescope is to use a high magnification level of 5D and higher, if you test your binoculars at this magnification and they do not show sharply, it is an average to below average optics, as an example I enclose a few live recordings to confirm this since I wrote, I didn't find You Tube better live recordings.
I believe that there will also be people in the USA who will build this type and confirm what I have written here.

A pretty good review of different sized solid tube Dobsonians. Very useful for anyone thinking about dipping their toe...
