A small comet with round coma, condensed nucleus and a hint of tail towards the left is seen moving among the stars. Equipment used: GSO N203/800 with TS GPU coma corrector. 58x30s from B3 skies of eastern Crete. Edited with DSS and SIRIL, image is cropped.

My first decent image of C/2026 A1 (MAPS). Located rather low for northern latitudes, it may become briefly very bright in early April as it plunges next to the Sun. Currently around mag 11, with condensed nucleus, round coma and hint of tail. #cometwatch #astrophotography

Stellarium graphic showing Venus, Saturn and Neptune close together just after sunset at 19:00 UT on 7 March 2026.

There is a chance to spot Venus, Saturn and Neptune close together just after sunset this evening. They will be very low to the west around 19:00 UT. Neptune will be very difficult to spot due to the bright sky. Binoculars or a telescope best for this one. #Astronomy

Blood moon lunar eclipse lights up skies around the world The full Worm Moon coincided with a full lunar eclipse creating a 'Blood Moon', as Simon King explains.

The M81/2 Group is one of the closest galaxy groups to our own Local Group, located approximately 12 million light-years away.

Messier 81 (Bode’s Galaxy): A massive, "grand design" spiral galaxy and the group's brightest member. It contains over 200 globular clusters and a supermassive black hole.

Messier 82 (Cigar Galaxy): An edge-on "starburst" galaxy. Its exceptionally high rate of star formation is triggered by tidal interactions with M81.

The Whirlpool Galaxy is a "grand-design" spiral galaxy located in the constellation Canes Venatici. It is one of the most studied and photographed objects in the night sky.

M51 is famous for its gravitational interaction with a smaller companion galaxy, NGC 5195 (M51b). This interaction has triggered intense star formation along its prominent spiral arms.
Composition: It contains an estimated 100 billion stars and has a supermassive black hole at its core.

Wow! A completely clear night and TEN hours of continuous 'shooting' at some cracking galaxies (described in ALT). The Dwarf3 smartscope was quite hot at the end!

Morning all…

This is my best shot yet of our galactic neighbour.

The Andromeda Galaxy (M31) is the nearest major spiral galaxy to the Milky Way, located about 2.5 million light-years away.

So in this photo, we are seeing the Andromeda galaxy as it was 2.5 million years ago.

This is the Blood Moon again, but this time 30 6-second images stacked. I think it might have gained a little bit in detail, but I might like the color better on the first one. #Astronomy #Astrophotography

The orange colour of my last post has long since gone as the waning gibbous Moon (99.6%) gains height.
