"Hi Dennis. Got the adjustable struts built today. The skies were clear this evening so I set up on the back porch.
End result - 42" strut length gives me a minimum 1 5/8" in-travel (tested all eyepieces with and without Barlow). Does that seem like enough to you? I could push it out a bit more but I'm going to be using a coma corrector and would like to keep things compact if possible. I really like the secondary mirror holder / adjustment. Very easy and intuitive. anyway...yay! Next up, mirror box. Thanks for your help - this was one of the more stressful steps for me. Nick"
