Newest model features new larger smoothly-sculpted
black plastic side bearing knobs for comfortably adjusting
optical tube tension (our suggestion). Loosening these knobs
also allows the optical tube to be slid forward or backward, so as
to set the optimum balance point.
Discontinued/old model had sharp-edged aluminium adjustment
knobs. Newest model GSO Dobsonians have knurled collimation knobs fitted to their primary mirror cell. This new feature allows much easier and more precise alignment of the mirror cell.
************************* There is absolutely no need to pay far more elsewhere for your next telescope or accessory!! Why miss out on our generous bonuses, too?
We have sold well over 2,000 GSO telescopes and consistently
receive glowing reports regarding their truly outstanding
performance! Compare! |
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! |
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 ************************* 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. 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. |
