Sorry I don't know brand of original, but new lens is GSO 2xBarlow Fully multi coated. (yes it's a cheap Taiwan brand, but will have to do for now) It has a longer tube than old one, if this makes any difference.
Have just read relating discussions on Barlows and am leaning towards an aprochramatic lens when I have the $$$$$. Seasons greetings all.
Can't beleive I missed the competition, but will still do for fun....
