1.25" GSO Barlow 3x or 2" GSO Barlow 2x
I am about to buy a GSO 10" DOB from Andrews which comes with four 1.25" EPs.
They also have the above Barlows for sale. Both have ED elements.
I want to order a Barlow when I order the scope. I would be happy with the 2x, but am a bit confused about the size (it comes with a 1.25" adapter).
Is there any advantage in having a 2" barlow over a 1.25" with your final EP being 1.25"?
Thanks
