Al, It depends on the optical design. In the Schiefspieglers I have designed and built the secondary requires around 6 degree tilt. No matter how much tilt is...
Dave, how much free tilt do you need to move a laser spot 1/2 across the width of the secondary? It seems to me that if the scope is well made, the tilt at the...

It strikes me that possibly some here may not be familiar with the CAD terms that have been mentioned recently so even though my experience is limited I'd like...
Dale there are three photos of a 8 Inch cell used in my ten inch OTA. That's as much time a I am going to invest in defending a simple design. Art ... going...
Art, I can't figure out from the CAD drawings or your description what is going on. Do you have a photo of the parts or a completed secondary assembly? Dale...

John, I don't see that in Art's renderings. By the way these are not photographics but computer drawings. Art states "The outer three threaded collimating...
Hi Dave, If you look at his photo of the secondary holder, you will see that the adjust/tilt screws do NOT thread into the support plate but rather press...

Dave, thanks for asking, I was wondering about the same thing. We tried adjusting a cell something like that once and it didn't work well at all. Ricardo, your...
Art, How much tilt can you get out this design ? Maybe I'm missing something but since the bolts are shown in your computer drawings to be threaded into the...
Thanks for posting this. It is a unique design and I think it would work quite well. I too designed my own secondary holder utilizing the ALT / AZ concept....
Hi Art, I think that for the primary the usual bolt and spring works reasonably, for the secondary I´ve been happy using this type on my newtonians...
