Oh drool, an ED120 f7.5 from skywatcher

You're right Geoff, they all specify the same fluorite glass.

John, I was not implying that these scopes would be as good as premium apos or that you are on "L" plates. I was merely pointing out that the scope appears to have the fluorite element you have mentioned as one of the ways of "eliminating chromatic aberration in a 120mm refractor". But I only read the info quickly and only on the ED120; did not realise the ED80 and ED100 were the same...

We can only wait and see what they are really like. I've seen them advertised overseas for a while but nothing closer to home yet.

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 .
