Message: <blockquote data-quote="Binastro" data-source="post: 3347118" data-attributes="member: 111403">The mountain phenomena sounds more like an 'Earth's shadow phenomenon', which I have seen in the Canary islands.As to distant binocular observations, the best for me must be when Titan occulted a 5th magnitude star.The star disappeared, then incredibly reappeared at mid occultation, being refracted by Titan's atmosphere, then disappeared before finally reappeared. That is rare. The distance, around 1.5 billion km.Titan was not seen at all in the binocular. So the whole event was almost unbelievable.What satisfied me was when a petulant observer thought the observation was over at mid event, when viewed in a telescope, and declared it over. He stopped his timings. A once in a lifetime happening and he blew it.I have seen two equally bright suns, having trouble deciding which was the real sun.Also an all sky halo display, which may beat my many aurora observations for amazement.</blockquote>
