I should add the 1.25 was purchased by me new in 2017 when I moved on from Baader Film,
the quality is not my issue ( I think), more a curiosity of would a larger unit make a change?
It’s most interesting to read of the quality inside from your post David.
That concerns me as my Lunt 40mm Ha scope has a b600 diagonal and filter unit, however that scope performs superbly and I have compared that to other kit of similar size.
Often the kit looks good on the outside, but behind scenes it’s not the same, something I call Hotel or Shop Front engineering.
Looks good up front, but ….
Are the Baader Cool wedges any better than the Lunt wedges for instance?
Or am I expecting just too much visually in WL with a 4” scope?
