Hi All.

I'm trying to get bigger image scale (photographic purposes) I use a 2X barlow after the diagonal on the refractor with the toucam at present. Which supposedly gives me 3X...I think I remember reading somewhere in here to get slightly better image scale, one can add an extension tube, would this be correct? & If so....would one add this extension tube before the barlow or after? (sorry if I'm totally wrong with this 'concept')

Thanks in advance.
