Hi Bob,
That's excellent news, always good to get at the end of the day. Was that trying the focuser out in anger while imaging ?
If it's any consolation I also burnt my fingers this evening. After drilling & tapping the beam couplers I wash them in warm soapy water to remove the cutting grease and then bake them at 150 degrees C for fifteen minutes to dry before inserting the grub screws.
Observation : very hot aluminium looks the same as cold aluminium but feels very different
Clear skies,
Dave
