First light!

Clear skies for the first time since whenever, so I thought I'd try it out. M42 was overhead and Jupiter was just in the field provided by my terrace. A shroud will make a distinct improvement and I will need to develop a light touch on the helical focusser as there is significant flexure in the OTA. Otherwise my calculations for the focusser position are spot-on. I will also need a variable tension control on the alt rings to allow for the eyepiece mass variations.
