What is the brand/type of your 2.5x barlow please?
Thanks,

Hi Glob,
It's just the GSO 1.25" 2.5x barlow. I'm actually interested to get a better one at some stage. Its not too bad depending on the eyepiece/scope combination. I also have the GSO 2" 2x ED which is better - but a bit heavy sometimes.
I checked the GRS transition at the Sky View Cafe website :-)
Regards,
Nick.
