Horsham Astronomy

Welcome to the Horsham Astronomy Group. Currently meeting at The Forest School and online on RingCentral on the first Wednesday of each month.

[Science at Millais School @Millais_Science]

How can we use light to study stars? #MillaisYear10 took part in a workshop by @SEPhysics @SussexUni to find out #MillaisAspiration #MillaisScience

The highest quality video of the moon was just released… this is so beautiful.

Arriving at the exact location , at the precise moment…. One tiny error and it doesn’t happen.

Simply amazing.

We are extremely sad to learn that deep sky expert and Astronomy Now columnist Owen Brazell has been killed in a traffic accident on his way to Kelling Heath Star Party. This is a tragic loss to the UK astronomy community. Our thoughts are with his family and all who knew him.

Tomorrow I'm doing my Astronomy Sketching and Art talk for Horsham Astronomy Group (I'll be on Zoom). I've completely re-written this talk from scratch because I've created a lot of new artwork since I last did it. I can't wait to share the pictures and stories of my #SpaceArt

@Dave_StarGeezer I like a Monty Pythons reference! - Monty Python

A clear night last night. Late to get set up, and managed an hour and a half before clouds appeared and I gave up. This is the very faint, challenging emission nebula Sharpless- 204. Called the Brontosaurus Nebula, probably because it's thin at one end, and what it is too! 😉

We were profoundly saddened to be informed of Dr Allan Chapman’s passing last week. We will present a full appreciation of Allan’s life and work in the March issue of Astronomy Now, along with his final article for us.

Planet or a pan? 🪐🍳

Sometimes, when planets are heavily zoomed in on through telescopes and filters, they form Earth-like textures, such as rust, streaks, swirls, and odd color stains. It’s just light, chemistry, and human imagination having a crossover episode.

4 circles, 2 of them are pans.

For a short time, the shadows of two Galilean moons appear together on Jupiter, framing the moon Io as it transits.

My images show how Comet C/2025 A6 Lemmon has changed in two weeks. As it moves away from us, it should start fading.

👀 #Astronomy, NOW! 

Telescope users may spot #Io and its shadow, together with the shadow of #Europa, in transit across #Jupiter’s cloud tops on the morning of 22 Oct (see graphic for 02:30 BST from the UK), & 29 Oct.

Jupiter on September 30th. Good seeing. Some interesting details across the disk. Oval BA at lower left remains quite faded though its orange colour has returned somewhat. The STB has revived to a degree not seen in many decades.

A quick capture of a supernova in a distant galaxy was taken a few nights ago.

Annual Picnic at Headley Heath. Bring a picnic for a relaxed evening meeting up with other Society members and viewing the night sky (weather permitting). So come and join us at 5.30pm on Saturday the 6th Sept at Headley Heath.

Vesta is passing an 8th-magnitude field star, offering an opportunity to see the asteroid’s motion on the sky over just a few nights.
