Looking at the Ioptron offering it says:
"Designed with the latest technology the 80 mm lens is crafted with a fluorite based, low dispersion glass that is ground and polished to exact specifications."
Is this definitely an ED telescope - I wasn't sure?? I know it says low dispersion (which of course ED is) - but I would have thought they'd say 'ED' if it was. Wondering if its actually a cheaper alternative? Anyone know?
Regards,
Nick.
