Using a dew shield now, so that does not work so well.
I did try using a dew heater wrapped around the secondary but it did terrible things to my stars. If you remember my image of 4945?
Like you said the collimaition is very close, just a smidge out really but enough to be a pain. It will get worked out eventually. I have jagged the collimation a couple of times now. When I did eagle and 5128 it was sweet but with the QSI on the back it tends to make it a little harder. No live view to work with, which is not great.
I am pondering upon what I will do with the dew problems. The heater really needs to be inside the assembly and that could be problematic given how fussy the rotational alignment is with these scopes.
More to work on though.
