Quite an impressive build. How hard is it to collimate the telescope? Does it hold the collimation?

Hi ! It is quite easy, with 2 tilt screws at the secondary cage, and the primary cell floats on three heavy duty springs. I can shake it and nothing moves, this is my first criteria. I collimate with a cheshire tool but always finish on a star at medium power (since this telescope realistically does not reach high power, since it would need 2mm eyepieces which are the opposite of wide field views). I use it with Explore Scientific 17mm 92 degree, and a 13mm APM XWA 100 degree eyepieces, and do star collimation with a 6.7mm eyepiece.

So most of the use is at 25x, to frame huge objects like NGC7000 or the largest extensions of M31

Barlow!?
Well, I could, but checking collimation at 1-2D magnification for an instrument used at 0.16D provides no observable advantage once star collimation was done. My rule of thumb is to star collimate at a higher power than actually used to observe
