Astrophotography shenanigans.

My attempt on Maffei 2 - a pretty sizeable disk galaxy, but hidden behind the Galactic dust curtain - so only very few images can be found on astrobin. I had to stretch it rather aggressively to get the faint structure show up prominently. bit.ly/4lB3t68 🔭#astrophotography 🔭📷

Our celestial neighbour, right now, from my backyard. SeestarS50 capture. Monochrome.
That prominent central crater is Theophilus.
It’s about 4km deep and 100km wide.
In its centre is a triple peak mountain that gets to about 2km high.
Mountains on another world, formed by an impactor.

This is really beautiful and gives a sense of altitude and column height.
[alt-text: a person standing on a snow field with a camera and tripod in front of them. Above them, are very bright green and purple aurora borealis. These look to stretch vertically into space. Stars pepper the background.]

Lots of shots to go through from tonight’s incredible auroral show over Dartmoor. Here are four of my favourites so far. While the camera does see far more than the naked eye, the colours in tonight’s display were the best I’ve seen in 30 years of mid-latitude aurora watching. #NorthernLights #Devon

Absolute scenes! The #aurora has gone crazy this evening here in Wales with vivid green and red visible to the naked eye. And don’t get me started on this beam which shot overhead for no more than 20 seconds. #astrophotography #photography #northernLights

Behold! My Solar System Christmas tree 🎄
Created 5 years ago, it’s a black tree with hand painted ornaments. Each year I added something new—asteroids from clay, moon ornaments, tree skirt, more stars, and even made it rotate. One year it was my favorite exoplanetary system, TRAPPIST-1. 🔭🧪🐡

Jupiter on Saturday morning in good seeing using the C11 with x2 Barlow.
I'd just recollimated the scope and cleaned the corrector plate, which I think helps, but the dew was awful!
This is probably my best Jupiter image to date.
More data still to go through

On this darkest solstice day of the year, my heart has dimmed, waking up to learn of the loss of dear colleague and mentor, Yannick Mellier. Yannick will be known to most as the lead of the amazing Euclid Space Telescope which will revolutionise our understanding of the Dark Universe 🧵🔭
![This square astronomical image shows thousands of galaxies across the black expanse of space. The closest thousand or so galaxies belong to the Perseus Cluster. The most prominent members of the cluster are visible in the centre of the image and appear as large galaxies with haloes around them in yellow/white, comparable to streetlamps in a foggy night. The background of this image is scattered with a hundred thousand more distant galaxies of different shapes, ranging in colour from white to yellow to red. Most galaxies are so far away they appear as single points of light. The more distant a galaxy is, the redder it appears.]

Star trails shot centred on Polaris from 16-17 December. Just over 3 hours of star movement. 😀 #Astronomy #Astrophotography

Nifty. Jean-François Gout caught this +8th magnitude flash of a Geminid hitting this nighttime side of the Moon this past weekend:

Finally processed my shot of this morning's Moon.
Always cool to see sunset over the Lunar Apennines.

A big shout out to the P7 class of Stockbridge Primary who took these utterly awesome photos last night on their residential visit to the Lagganlia outdoor learning centre in the 🏴 Highlands. Lagganlia is part of the Scottish Youth Telescope Network and I'm so proud of these kids! 🥳 🔭 #SYTN

A nice little pairing. This is the Bubble Nebula in the lower left, and the open star cluster M52 in the upper right. The Bubble is devilishly hard to get right. A least, I find it so. #Astronomy #Astrophotography

The Pacman Nebula NGC 281 in Cassiopeia had been on my wish list for several years, and now, over the course of 4 nights in September & October, I finally got it. Visually not an easy object due to light pollution, but really fun to photograph (tech. details in image) 🔭
