Finally got a session with clear skies to continue the testing of the Mk2. Tube is still a bit too long and I can't quite get focus with a couple of my longer bodied eyepieces when using the 90 deg diagonal or barlow. Looks like final tube length will be 145 - 150mm, but reached the limit of trimming with the existing mounting ring arrangement. DSI and Agent webcam focus with about 25mm of inward adjustment left.
Bracket for the red dot finder has been made and fitted, works a treat
How did yours go at Magellan Chris ?
