I assume from what I have read so far that there are no significant viewing differences with using either a 2" or 1.25" barlow with 1.25" EP.
At the moment I'm swinging towards a GS 2" barlow (achromatic) as I already own a 2"EP as well as my 1.25's.
I presume a cheaper achromatic style will suffice for my viewing purposes.
I'm looking at one from aquila optical (
www.aoe.com.au)at the moment. Does anyone know of any better deals elsewere.
Better still if anyone wants to sell there's I'd be interested even if it was a 1.25".
