SHIPPING & INSURANCE NOTES

Insurance cover for goods in transit is available from us for only $2 per $100 value of goods. Please advise us if you require this option when ordering.

Please consider insurance because we are not responsible for loss of parcels or damage sustained by parcels as the carrier is responsible! We do pack well! If your order (e.g. telescope or binocular) is damaged in-transit by the freight company then you must claim on the freight company, not ourselves!!

Of course, if you have paid us for insurance then you simply claim on us. We are quick at resolving damage claims, compared to
many freight companies.

Please do NOT write <fragile> on anything you send to us as doing so greatly increases the risk of damage. Please try to "double-box" all products sent to us.

Important notes re GSO mirrors...

GSO mirrors are guaranteed  diffraction limited. They achieve the theoretical limits of resolution for their respective surface areas.

GSO Newtonian Dobsonian telescopes have BK7 type glass paraboloidal mirrors and are precision figured and polished to an absolutely outstanding 1/12 (or better) surface wave specification!

I have witnessed this exacting and time consuming process numerous times, along with the confirming surface wave error printouts from GSO's three laser double-pass interferometers, during my many visits to the GSO factory in Taiwan.
Lee says most competitors don't visit any overseas factories, ever!

The high industry standard for mirror surface wave specification is 1/10 wave, yet very, very few telescope manufacturers regularly achieve it.

Due to continuing and dedicated quality improvements at GSO, more and more optical accessories from GSO are now achieving an amazing 1/16 surface wave spec.!
GSO guarantees no more than 1/12 surface wave error. Outstanding!
We know of no other manufacturer achieving such high quality levels at similar pricing...
 
OPTICAL DESIGN NOTES

Ritchey-Chretien astrographs are generally regarded as being the best design for astrophotography.

Ritchey-Chretien (RC) optical designs are generally regarded as being optically superior to Schmidt-Cassegrain (SCT) designs
and "edge" corrected SCTs due to their resulting flatter field.

  Schmidt-Cassegrain optical designs are generally regarded as being superior to Maksutov-Cassegrain designs due to their higher light transmission, etc.

*************************

Prices are subject to change due to recent exchange rate variations.

Please remember that warranty may be void if you internally disassemble any telescope, regardless of model.
Customer-caused or environment-caused damage is not covered by warranty, of course!

*************************

OUR SUGGESTIONS

GSO adopted all our suggestions re releasing right-angle correct-image finderscopes, standardising on f/5 focal ratio for large aperture GSO Dobsonians, upgrading to 2" focusers on all 8" and larger aperture GSO Newtonians, fitting larger diameter and smoothly-sculpted side tension knobs to Dobsonians, employing
extra heavy duty TPL tripod legs, standardising on white colour for
metal tube OTAs, fitting cut-foam inserts into accessory boxes and labelling all those boxes, etc., etc.
