Hello,

Some v quick grabs (SF50 etalon, ASI290MM).  I really can't get the gradient merge to combine the top & bottom bits of the disc properly (there's a v clear join) - and unfortunately MS ICE doesn't work either.  So it's frustrating wrt whole disk images.  I suspect I'll have to put a reducer in - currently have 0.79x but that's not quite enough.  Playing around w astronomy.tools suggests somewhere like 0.67x should work - but can reducers be chopped & changed?  (My scope is a 76mm f6.3, so w etalon it becomes f9.6 so I would need a reducer that can do 0.67x (or lower) for f9.6 scopes - is there such a thing?).

Anyway, stay safe all.
