"A kilometre-sized Kuiper belt object discovered by stellar occultation using amateur telescopes"

Thought this was both interesting and relevant to PANOPTES. The lab used two 11" Celestron RASAs with ZWO AI1600mm CMOS cameras and found a kuiper belt object. :slight_smile:

Here, we report the first detection of a single occultation event candidate by a KBO with a radius of ~1.3 km, which was simultaneously provided by two low-cost small telescopes coupled with commercial complementary metal–oxide–semiconductor cameras.

The OASES observation systems are capable of monitoring up to ~2,000 stars with magnitudes down to V=~13.0 in a 2.3×1.8° field of view simultaneously, providing signal-to-noise ratios comparable to or greater than 3–4 with a sampling cadence of 15.4Hz at an extremely low cost (~US$16,000 per single system).
