商品描述
Introducing GSO's renowned line of Newtonian telescope optics now available in the US market! Known for their exceptional quality and reputation as top-notch mirrors within their price range, GSO's dobsonian telescopes have delighted users for years.

Our range includes parabolic primary mirrors perfect for telescope DIY projects or mirror replacements. These mirrors, crafted from optical grade BK-7 glass, come in apertures from 6” to 16” and various f-ratios. With a reflective aluminum coating boasting 92-93% reflectivity, safeguarded by a silicon oxide (SiO2) over-coating, these mirrors ensure remarkable optical performance with minimal light scatter.

GSO employs cutting-edge manufacturing and testing processes, ensuring high-volume, top-quality output. While GSO guarantees diffraction-limited performance, their mirrors typically offer a mirror surface quality of at least 1/16 wave RMS, often even better.

In addition to parabolic primaries, we provide matching GSO secondary elliptical mirrors, mirror cells, and spiders, each available separately. Keep in mind that most mirrors may have minor uncoated areas near the edge, caused by coating chamber clips – these are not defects, as they're typically covered by your mirror cell's clips.
