π The Moon will reach apogee (farthest from Earth) at 6h UT (now) on 17 December. At this time the Moon's distance from Earth will be 406,322 km or 252,477 miles and span an angular size of 29.4 arc-minutes. π

M24 is a star cloud located about 10kly away in the constellation of Sagittarius.
Not an object per se, but a hole in the dust and gas of our Galaxy. We are seeing millions of stars deep into the Galaxy. #astronomy

On the third day of CMBmas, my telescope gave to me:
Three working SATs π
Two optical designs
and a low PWV
Last winter, we fixed a cracked lens in one of our Small Aperture Telescopes. We put it back on its' platform and it's now scanning the sky again.

3I/ATLAS is flying by right now. Its closest approach to earth is in a couple of days. I have been collecting data every clear morning. Here are some results from this morning. 3 images. One is 5 one minute exposures stacked. Another is 3 exposures over about an hour. It is moving fast! #astrophoto

Our interstellar visitor, comet 3I/Atlas has been getting lots of press. After several unsuccessful attempts, the skies cooperated at 4:00 AM today and I got a pic of it. Will be closest to Earth on Dec 19th, and visible with a small scope in dark skies.

Jersey Skies: Send your name around the moon!
If you want to vicariously travel with them to the moon, NASA has an opportunity for the public to send their name to lunar orbit during this mission.

Pulsar planets are rare, but this one is even rarer amongst the rare! π
#JWST observed Jupiter-mass PSR J2322-2650b, finding it has a helium/carbon-dominated atmosphere, and may have carbon clouds that form diamonds.

A galaxy with non-smooth features, observed with the Hubble Space Telescope in the CANDELS-GOODS survey.
It is at redshift 1.12 (lookback time 8.41 billion years) with coordinates (53.20235, -27.75128).
77 volunteers classified this galaxy in Galaxy Zoo CANDELS.π

What's causing these weird blue flashes in the sky?
A new study suggests an extreme explanation: The most recent flash probably came from a giant star, 10x the mass of the Sun, being completely consumed by a black hole in just a few days. Ulp. π§ͺπ

I've been trying a few new processing methods.
This is a rework of one of my better Mars images taken almost exactly 3 years ago at around it's closest approach to us.
The bright circle upper-right of centre is the volcano Olympus Mons. A few others are also visible.

#Astrophotography isn't just about gear. Patience and practice are your best tools. And don't forget to ask questions. Others have probably had the same problem you're having. You can learn more at astropotamus.com/learn
