Hi Folk
Just to add my two bobs worth.
I have a 5"ED F6.4 Borg APO it only has two elements and in focus shows no colour on the Moon Jupiter etc where as the old TV Genesis did ( a little bit ).
Out of focus it shows lots of it , but well I prefer to look at stuff in focus anyway
.
When CCD imaging I need to shift the focus very slightly between filters and for modded DSLR need to use a IR blocker.
Should it be called APO probably not , nice scope though.
Heres a pic taken with it and Borg flattener ( F5.4 ) and IR blocker sorry about the colour , needs a bit of tweeking .
