I have used this for many years with good results. There is a small yellow mark on the casing, which does not affect performance, I used this mark to align the MPCC for the right orientation.
The MPCC would be well suited for Newtonians around the F5 or F6 range.
It also includes the little ring for finer adjustment of the Back focus, which is 55mm.
Looking for $200 Posted to anywhere in Australia.
