I'd love to see a similar video with your eye at the eyepiece and your hands on the motion control knobs. I've been wondering all along about the reach required. Apparently it's quite comfortable, but I'd like to see out of curiosity.
The video is nice but there's a lot more to this type of mount than basic movements. What happens when you take the 26mm Nagler out of the diagonal, when the scope is pointed low on the horizon - does it move or stay put? That's what I really want to know. I use a 35mm Panoptic as a finder eyepiece and routinely switch between it and tiny orthos. If the scope moves in this situation it's nearly useless for me.
I'm using an f/9 Vixen 102 so the focuser is a long way from the midpoint of the tube.
I'm considering upgrading from a Teegul. But I like the way you can tighten the tension on the Teegul so that it never moves with eyepiece changes, or even taking the heavy diagonal out.
Also with the Teegul the slo-mo knobs are right next to each other so you can easily operate both with one hand. For longer OTA's you can put slo-mo cables on it and the two slo-mo handles are right next to the focuser.
But one problem with the Teegul is that it doesn't lift the scope high enough off the tripod. And also the scope's weight is always off to one side of the mount and tripod, which is definitely bad for stability. The half hitch solves those two problems.
