We are back at our normal venue from 3rd Sept. 2021 |
This page lists our monthly meetings. For other events open to the general public, see our Events page
Dates are set well in advance but the 'content' of the meeting is only updated (from our 'meetings database') when details are entered, so 'blank' or 'TBA' may be shown when data has not yet been entered (please be assured that the meeting will take place and a talk on (some) Subject will be delivered by (some) Speaker ! )
During the COVID-19 restrictions, all meetings are being held on-line using ZOOM. Meetings are normally held at the Church Hall (aka 'The Soltau Center') of St James-the-Less, Stubbings, Maidenhead SL6 6QW, from 7.30 (for a ZOOM link, or map and directions, see the About MAS (Where we meet) page
The Main Topic is usually delivered by an invited guest speaker. We aim to provide a diverse range of subjects linked (in some way) to Astronomy - whilst the 'Second Session' is typically delivered by one of our members. If time allows, the evening concludes with a short 'What to see this month'.
Details of a typical evening (times are approximate) :- 7.30pm. The evening starts with the Chairman delivering any important Announcements and then introducing the main speaker. 7.45pm (latest). Main Topic Speaker gets up and the lights are turned off. If you arrive after 7.45, please enter the Hall by the first door (on the right, after the entrance) and please be extra careful when finding a seat at the back of the Hall as members often setup telescopes there ! 8.45-9pm +. Coffee break during which visitors often chat with members who have set-up their telescopes at the back of the hall. If the weather is good, sometimes members will nip out for a quick look at the sky. Smoking is permitted outside the Hall, however smokers are asked to avoid any 'observers' (smoke particles always seem to get into optical equipment, no matter how well 'sealed' it may be) 9.15pm (at the latest). The 'Second Session' then runs for about 45 mins, typically ending with "What's Up !" (what to look out for in the sky this month) 10pm. We aim to clear the hall by 10pm. Post meeting Observing. If the weather is good, the Observing Organiser then leads the way to our chosen observing site, or (if the weather looks even a slight bit 'iffy) members sneak off to the local Pub instead :-)
Next meeting :
(+) 7 Jun 2024 MAS 67th AGM - (Annual General Meeting)
Meetings Archive |
The meetings archive gives an 'overview' of the Society activities over the past 10 years (see also the Events page).
Members have access to the full 'History of MAS' (including AGM minutes going back to 1957) along with full names and photos
The MAS 'year' runs from September of one year to June of the following. The end of year AGM in June elects the Committee for the following year (there are no meetings in July and August - although often members will meet informally at the local pub - which gives the new Committee time to 'get a grip' on running the Society)
The "short cuts" (in the 'title bar', at the very top of this page) will take you to the June AGM entry for the end of that MAS year
The Maidenhead Astronomical Society meetings archive (last 10 years only)

(-) 7 Nov 2014 Guest stars ancient and modern - (Guy Hurst)
The ancient Chinese left extensive records of all sorts of 'naked eye' astronomical events, including 'guest stars' (Novae and Comets) which were seen as 'portents' predicting the future. Nova are easy to distinguish since they are recored as 'not moving'.
The earliest recorded supernova, SN 185, was viewed by Chinese astronomers in 185 AD. Then came SN 1006 (in Lupus), the brightest recorded supernova to date. Next was SN 1054 (in Taurus, which produced the Crab Nebula), then SN 1572 (in Cassiopeia, observed by Tycho Brahe) and SN 1604 (in Ophiuchus, observed by Johannes Kepler and the last in our Milky Way galaxy to date).
SN 1572 and SN1604 were used to argue against the Aristotelian idea that the universe beyond the Moon and planets was "immutable" (Ed. a belief promoted by the Church, with it's Geocentric model of the Universe, which claimed that the 'perfect unmoving stars' are the outermost 'heavenly sphere' and, by implication, the underside of Heaven), however the distance calculated, whilst outside the 'earthly sphere', was orders of magnitude too low.
With the development of practical telescopes, in the early 1600s, observers started to examine the night sky and, in 1885 discovered the first supernova in another galaxy, SN 1885 'S Andromedae' (in the Andromeda galaxy) as well as observe the SN remnants
During the 1930s, Walter Baade and Fritz Zwicky examined what was believed to be just a brighter class of 'normal' novae and, after discovering that the process was completely different, coined the term 'super-novae' (since then SN have been clasified into 2 main types (Type I and II) with a number of subtypes).
By the 1960s, astronomers found that the maximum intensities of supernova explosions could be used as 'standard candles' and thus used to calculate the distance to the host galaxy (see last months meeting, Measuring the Universe)
SN 1987A, in the Large Magellanic Cloud (about 168,000 light-years away) was the most recent SN close enough to be a 'naked eye' object (but could only be seen from the Southern Hemisphere).
These days it is possible to 'reconstruct' and date ancient supernova lacking written records by using techniques such as light echos (which confirmed SN 1680, Cassiopeia A supernova event) and by 'back plotting' emissions from the supernova remnant (eg. RX J0852.0-4622).
UK amateur astronomers have been particularly successful at discovering SN in other galaxies, with Tom Boles, with his slide off roof observatory in Coddenham achieving the world record with SN 2009ij, in August 2009 (when he reached 125 discoveries) and which he still holds today (with 155 discoveries)
The uneven distribution of SN by galaxy 'type' (more often in spiral than elliptical galaxies) still needs to be fully explained.
Ed. Type I supernovae (binary pairs) mostly occur in elliptical galaxies, and are probably mostly Population II stars, whilst Type II supernovae (massive stars exploding) are not observed to occur in elliptical galaxies (at all), and are thought to occur (only) in Population I type stars in the arms of spiral galaxies.

Second half
Tim followed up Guy's talk with photo's taken from his garden observatory of the most recent SN discovered, by Ron Arbour (BAA, his 33rd) (so new, it was still designated 'PSN' = Possible SuperNova)
Details by Tim:
Using a 30cm F/4 Newtonian (Orion Optics, Crew) on EQ6 mount without auto guiding, I took 10 exposures of 20s with an ATIK 314L+ (cooled to -15C) focused with a Barhintov mask (Ed. you can make your own following these instructions using a free on-line tool).
A Baader MPCC was used to flatten the field. No dark or flat frames. The exposed frames were staked in Deep Sky Stacker (Ed. freeware) with 2x Drizzle and saved as FITS, and then stretched in AstroArt 5 (Ed. Euro 129, or £125 if purchased via UK distributor).
I did a background correction before saving as jpg. Further adjustments were with Paint Shop Pro 5 (Ed. an old version that has been included on magazine cover discs). The magnitude limit on the frames is about +18.
Sky condiitons: Full Moon Rising, and dusk on 2014 Nov 5th, 1824 UTThis was followed by Robin with a Stellarium 'script' tour of open clusters near Cassiopeia finishing with a reminder of next two meteor shower dates (Leonids, peak Nov 16 = for which we are holding a public viewing event on the 15th, and the Geminids, peak Dec 13)
