Sea of Crises

Whenever I write the name of the Sea of Crises, or Mare Crisium, I wonder what crises it could be refering to. Some vast hurricane perhaps?

Wargentin and the value of sketching

I have been looking forward to an opportunity to sketch the moon for some days. Last night we had cloudless skies and wonderful day 11 moon, so out I went. What a disappointment it was though, because the air was very wobbly, meaning that nothing came into sharp focus, and use of high power was impossible.

Bays, projections and the limits of visibility

Wow what a night of variety! This included a comet, weird weather on another planet, missing galaxies, disappearing galaxies, and some new first sightings.

A comet, an extraterrestrial storm and an extra-galactic cloud

In other words…..I went stargazing last night. First time in ten days or so that clouds had permitted. Phew!

Double rainbow

Since we’ve been under cloud and rain for almost an entire week, there’s been no opportunity to stargaze (very frustrating given what’s supposed to be visible at present), and well no wildlife either. But I took the opportunity to snap this sky feature last week: a rare double rainbow.
