Hi All,
It's been nearly 13 years since I posted on crater Janssen. I thought it was a pretty good pic
.
Have a look and compare to the current post. I'm rehashing the comments from then....
Janssen is the large depression that has seen better days. Named in honour of Jules Janssen who was a 19thC French astronomer who built an observatory atop Mont Blanc (as you do) and also discovered Helium (again, as you do).
Fabricius aka David Goldschmidt was a 17thC German astronomer who discovered the first variable star - Mira and also that the sun rotated.
Metius, aka Adriaan Adriaanszoon, worked for Tycho, and his brother was making telescopes at the time Galileo was pointing them upwards.
Brenner is the pulverised depression named after Leo Brenner aka Spiridon Gopčević who was a 19-20thC amateur planetary astronomer.
Steinheil, Carl August von, was a 19thC German astronomer who was professor of mathematics, industrial strength optical instrument maker, telegraphy designer, administrator etc etc. Clearly a very lazy man....
Watt, as in James, was an 18thC steam entrepreneur/engineer who probably never looked up much. His connection with the moon is his membership of the "Lunar Society of Birmingham" - a group of like - minded industrialists who met every full moon. The Society included Josiah Wedgwood, Erasmus Darwin, Joseph Priestly and other luminaries of the time. It was said that they derived their name from meeting during the full moon to allow safer travel at night to and from their meetings.
Rheita crater and Valley, are named for Czech astronomer and optician, Anton Schyrle of Rhaeita (1597-1660).
ZWO 178mm camera, Celestron 9.25" telescope. Approx. 2,000 frames stacked in Autostakkert!3 and sharpened in Registax.
