Mexborough & Swinton Astronomical Society
@msas78.bsky.social
Formed in 1978 with just five members and meeting in members front rooms over the years the society has grown into a group of about fifty members who meet every Thursday evening.
The Society also own and runs its own observatory at nearby Hoober Stand.

Many thanks to the MSAS members and public who turned out for this year's 'So, Santa brought you a Telescope'. On a cloudy, cold and drizzly day eight members of the public with three telescopes visited the J A Jones Observatory. Lots of questions were answered and lots of problems solved.

If Santa left you a telescope (or if you have one at home gathering dust) and would like to know how to use it, bring it to the J A Jones Observatory on the 27th of December 2025. There may also be an opportunity to look around our observatory.
Happy Christmas and Clear Skies!

MSAS' Tom W. took this image of LDN1337, a dark nebula in Cassiopeia, in November. He used a UV/ IR cut filter and took 4.5 hours of 120s subs. Tom reports the filter is best used when there is little Moonlight and is one of the most difficult objects he has imaged and processed.

MSAS members wrapped up 2025 meeting programme with the Annual Christmas Party. This year we were entertained with a Roy G quiz. Kris emerged the winner! Simon B shared this image from the recent Geminid shower. Simon took over 200 images with a Canon 600D for this single success!

As the rest of MSAS are trying to find clear skies Andy D (who lives in south-east Spain) is basking in sunshine. Andy sent this image, one of three, showing the development of a class X5+ solar flare on the 11 November. Don't forget the suncream Andy!

MSAS welcomed back Dr Colin Steele who introduced the book 'Flatland' by E A Abbott and the works of C H Hinton describing the adventures of A Square, a character from the prior. He described gravity, eclipses, the difficulties in making out the orbits of planets and mapping constellations in 2-D.

With Andromeda being close to the zenith this is good time of the year to have a go at imaging the Andromeda Galaxy, M31. MSAS member Mike S took this image a few weeks ago. Mike reports the image is 1473 x 10 seconds (a little over 4 hours) subs taken with a Vespera Pro, stacked but not processed.

Andy K-V shared his image of the 'Silver Sliver Galaxy' NGC 891 with fellow MSAS members last week. The galaxy is a member of our local super cluster and is approximately 27Mly away in the constellation of Andromenda.

MSAS welcomed amateur astronomer Adrian Smith this week who described the universe from the view of the both General Relavity and Quantum Physics and the scientists, Albert Einstein, Max Planck, Erwin Schrödinger, Paul Dirac (and others) who showed how quantum effects shape our observations.

Cleveland & Darlington AS' Neil Haggath presented this week's meeting. He regaled us with tales of astronomical mishaps through the ages including the american hit by a meteorite weighing 3.8kg and survived, the 30+ year feud between two members of the RAS and the unluckiest observer in history.

Comet Lemon was in the evening skies in October and November but quite a difficult object for many observers. MSAS' Tony M managed to capture this image using a SQA55 telescope (109 x 10s) from the observatory grounds on 25/10/2025.

MSAS welcomed back Dr Ed Daw from U. of Sheffield this week. Ed discussed dark matter and how the theoretical axioms that could be the solution and introduced the QSHS project and 'The Fridge' detector at Sheffield anticipating the first data runs soon.

MSAS' Roy G. is an avid fan of the Moon and took this image on November 1st with his Seestar S50. Roy's image shows, very clearly, the asymmetrical ejecta pattern from the the crater Proclus between the Seas of Tranquility and Crises.

This week MSAS welcomed Tom Gillespy of Alyesbury AS. Tom described Tsiolkovsky' Rocket Equation in depth, explaining along the way why Δv matters when trying to get anything off the Earth's surface. He showed how rockets are inefficient the and the measures used to overcome some of these issues.

Comets are difficult objects to see in the UK, mainly due to the weather, but this autumn Comets Swan(C/2025 R2) and Lemmon(C/2023A6) have been visible. MSAS' Phil M took this image of Comet Swan on the 27th October from his back garden managing to avoid the glare from the street lights.

This week's speaker was John Jack McGill from Michigan, USA. John described how his interest developed after buying a telescope for his son and becoming interested in astronomy. He went on to share the equipment and preperations needed to get an 'up close and personal' photograph.

MSAS member Simon C. observes from a suburban site but can still take advantage of clear nights with a Celestron Origin. Simon took this image of the Elephant's Trunk Nebula, IC 1396A, part of a much bigger gas cloud IC 1396 in Cepheus some 2,400 light years away.

Adam McMaster gave the MSAS weekly meeting with a talk on the star HD38451. In 1848 John Russell Hind observed this star as red but over the next two years watched it turn to blue. Adam showed how modern methods have revealed it to be a shell star spinning at high speed casting off material.

MSAS' Paul D'Silva usually fronts the meetings but this week, after the speaker had to cancel, presented a talk on the Gemni Project. Paul described how NASA had to squeeze a program between Mecury and Apollo in order to fufil President J F Kennedy's dream to land a man on the Moon by 1970.

MSAS' busy Programme Coordinator Roy G. still gets time to take images and managed to take this one at the end of September with his Seestar S50 from his back garden for this image of the Pacman Nebula, NGC 281. Roy not only has to contend with urban light pollution but also a busy train line!

This week MSAS was visited by Dr Vincent Eke who explained how he used computational models to explore how the Moon was created. He described the three major pre-Apollo era models and how his work shows that a model based on elements of all three models fit the geological evidence bought back.

MSAS members got together on Monday & Friday last week with their smart telescopes to share their know-how, and skills at the J A Jones Observatory. Apart from Seestars S50s there were examples of Celestron Origins, Unistellar Evscope and Vespera Pro giving the chance to compare and contrast.

Ian Muirhead outlined the difficulties faced by operators of satellites constellations and astronomers as the skies above the Earth become more crowded. He showed how the number of satellites has increased to over 15000 and the issues to be solved as launches to LEO and beyond become more difficult.

Last week MSAS' Tom W took this image of M13 in Hercules. Tom also caught the galaxy NGC 6207, to the right, which is a spiral galaxy some 30lyr away. However, look out for IC 4617, just below the line between M13 and NGC 6207. This is galaxy 553 Mlyr from the Milky Way and slightly larger.
