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 :
(+) 2 Sep 2022 InfraRed Astronomy - (Dr Eric Dunford)
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

Friday, 7th October 2016 - Astro tourism - David Phillips (Naturetrek)
Report by Steve
David Phillips, formally Operations Manager at Intrepid Travel, will delivered a talk on Astro-tourism - a subject dear to his heart as he will be introducing Astronomy themed holidays at Naturetrek.
He started with a quick overview of what astro-tourists like to see = the Northern Lights (aurora), Solar Eclipses, dark sky observing and trips to astronomical observatories. He then talked about some of the trips he has organised and showed a number of photos in each category.
Northern Lights. Whilst we are now moving away from the solar max. you might expect fewer 'outbursts', however we actually see more, especially during the 'active' months of Sept/Oct and Feb/March.
To view the aurora, the ideal place is on a 'donut' ring around each magnetic pole called the 'auroral oval' - the northern one includes Alaska, N. Iceland, N., Greenland, N Scandinavia etc. For a good view it's also important to avoid bright moonlight (so travel when the Moon is 'new')
Solar Eclipse. A total Solar Eclipse is a 'must do' item fro your 'bucket list' !
If you missed the last visible from UK (11 August 1999) you will have to travel (the next total from UK won't be until 23 September 2090). Next year a total eclipse will be visible from much of the USA on Aug 21 (see the MAS Eclipses page). One tip from David is that the Eastern / seaboard is likely to get the best weather (and thus the best views)
David displayed some amazing photos of past Solar Eclipse trips he had organised, the most amazing of which was one of the Sun's corona at 'totality' in Svalbard, 2015 .
He also showed the tent village setup on an atoll (for the 2010 eclipse), the 'shadow bands' on the ice/snow in Svalbard for the 2015 eclipse, and visitors viewing the 2016 eclipse from Indonesia (from the tiny island of Ternate).
He also mentioned two forthcoming trips - USA for 2017 and Chile/Argentina for 2 July 2019, and that researching local cloud cover was key to success !
Observatories. He has organised a number of tips that included Observatory visits and notes that while many (especially in USA) are happy to receive visitors, and run active 'outreach' / 'history' programs, some (S. Africa ?) are not (although he has managed to 'blag' his way into some 'unofficially').
Observatory visits can be combined with other activities - for example, Arizona you have Lowell Observatory, Meteor Creator and the grand canyon all in one trip !
Dark Skies. There are a number of places where the local hotels offer facilities - esp. Morocco, where he showed photos of a hotel on the edge of the desert with telescopes on the roof and Namibia where the amazing dark skies can be combined with a wildlife tour.
After the break Adrian J. delivered an appeal on behalf of the Gaia - GOSA Project from members to observe asteroid 'light curves'.
Gaia is an ESA all sky survey satellite that is measuring the position and magnitude of stars to unparalleled accuracy. During the planned 5 year survey it will observe each of about 1 billion stars (about 1% of those in our galaxy) about 70 times. It will spot about 300,000 asteroids, obtaining their position and 'instantaneous' brightness. The 70 odd 'snap shots' will generate a 'sparse light curve' of each asteroid as Gaia catches it at different points in it's rotational period (which is typically 8-12 hrs).
Gaia-GOSA is a ground based project by 'amateurs' to generate 'dense' light curves for those asteroids. The Gaia 'sparse' observations will allow the GOSA dense curve to be 'calibrated' (so long as the Gaia measurement is made during the GOSA observation)
What's so exciting is that from the 'dense' light curve it's actually possible to compute the shape of the asteroid !
How MAS members can help. You need a decent CCD camera (capable of 2-3minute exposures without 'saturating' the asteroid), an 8" (min) 'scope and a mount that can keep the asteroid 'in view' for at least 1 hr i.e. for the minimum 'session'. Your timing only needs to be accurate to within about 1 second, however you will need to generate at least 1hr of data 'per session' (5 hrs is better :-)) and the Gaia 'snap shot' of the same asteroid MUST take place during your session if your data is to be 'calibrated'.
When you register with the Gaia-GOSA website (and input your observing location), you get lists and times of the asteroids (visible to you) that Gaia is due to observe. Since rotational periods can extend to 12 hrs and beyond, the same asteroid typically has to be observed multiple times (and from different time-zones).
Note that you don't process your images, just post the 'raw' FITS data (the GOSA computers will locate the asteroid in each photo and extract it's brightness).
A 2-3 minute exposure per image is needed to reduce noise (and get the required 100 SNR), so 'pin sharp' focus is not required ('pin sharp' will lead to faster 'saturation')
All our indoor Meetings are open to the public, however non-members are asked to make a contribution of £2 toward the hall hire costs (this may be collected by Fred, our Membership Secretary, at the door on arrival, or left at the 'Tea hatch' at half time).
