Today is the * first * day where the sky is clear at day's end since early October.  That is the rainy season at the edge of the Amazon-Cerrado ecotone for you.  A good one this year too!  The river has risen almost 3 meters already and we are hoping for a big flood.

 

It caught me completely off guard.  I will not be setting up the 12" Dob in a hurry, and I will not be obsessively dark adapting.  The Moon is out anyway.  But I might go out with the 10x42 binoculars and have a look at the Moon, Mars, rising Orion, Andromeda, and the Sculptor Galaxy.  No doubt it will be the last for many months.  But I will have to brave a swarm of stinging biodiversity, so it will be brief.

 

Now, if the 127mm wooden refractor were built, instead of a bunch of parts sitting in a box waiting for me to have the time, that would be a different matter.

Good luck and greetings from Canada. If you are able, as I'm not sure it's in your sky, try to get a look at comet 46P/Wirtanen. Many in NA and EU are seeing it in binos. It's in Taurus tracking toward Pleaides. Pleiades

Seconded. It is also an easy catch by naked eye from a dark site (like where I live).

Well, it turned out to be a perfect evening for observing planetary detail.  Near the terminator, I was able to see wonderful atmospheric scattering and diffraction effects on the light of a nearby star.  Gaseous H2O and dust particles were easily inferred, with local density variations expressed as color differences.  Later, a few nearby stars were also briefly observed, heavily extincted by the intervening molecular gas clouds.  Somewhere behind it all, no doubt, there was a comet.   grin.gif

I can confirm it!  Glad you got some sights in.
