ARP 286 is a small group of peculiar galaxies, NGC5560, 5566 and 5569 about 50-60 Mly away in Virgo. They're gravitationally interacting and in particular the two spirals appear distorted.

C23 aka NGC891 is an edge-on spiral galaxy in Andromeda. Its about 30 Mly away. I quite like this one because its pretty much what our own galaxy would look like edge-on.

Kid-at-xmas levels of excitement (did I wake up at 5am - yes I did!) #RubinFirstLook

The Virgo cluster is an inspired choice: three-cheers for Sinclair Smith and his 1936 observations of it which helped Zwicky conclude there must be invisible #darkmatter out there! 🤓 🔭🧪

M42, the Orion nebula.
I barely processed this at all - i stretched the stack a little but otherwise its pretty much straight off the camera.
M42 is an emission nebula in Orion, lit up by new, highly luminous stars.

Imaged with the RC8, H294C.
Best 10% of 2300 frames (2 mins video)
Stacked in Autostakkert 4, processed in Registax & FastStone.
Three galilean moons visible, plus the red spot.

IC434, the Horsehead. This is 40 minutes of data captured with my RC8 and Altair 294C, stacked in DSS and processed in Pixinsight.

Its interesting to note that IC434 is actually the bright nebula *behind*. The nebula is about 1200 ly away and is an HII region being ionised by Sigma Orionis.

A bright fireball was seen this morning at 0147 on 2024-03-02, unfortunately through thick cloud on many cameras. Several visual sightings too - if you saw it please do file a report via our website.
Analysis hopefully incoming!
