News and items of interest to Herefordshire Astronomical Society members
We are delighted to announce HAS member Dr Steve Foulkes will give us his talk "Cataclysmic Variables". This talk will be held at the Kindle Centre in Hereford.
Those with very long memories may recall that this is the second time that Steve has given a talk to HAS. He gave a talk on searching for supernovae in our very first year of existence 2008 - so it's about time we invited him to give us another!
As always, look out for emails from Chris with details of what HAS is doing next. If you are not on our emailing list, please contact Chris for the latest news - contact details here.

Cataclysmic Variables
Dr Steve Foulkes (HAS)
We were lucky with the weather for the Partial Solar Eclipse on Saturday 29th March. The sky was reasonably clear for first contact at 10:04 and the clouds mostly kept away until after maximum eclipse just before 11:00.
There was a great collection of observing equipment - projecting scopes, H Alpha scope, Herschel wedges, mylar viewing glasses and, of course, the traditional colander.
Everyone was able to see the partially covered sun, the collection of sun spots spread across the sun's surface and some prominences on the edge of the solar disk.
Many thanks to James and Wyevale Nurseries for allowing us to use their private car park to safely set up our equipment, park cars and vans and enjoy the selection of cakes and nibbles that Keith and David brought along.
Here's a taster of what we experienced on the day:
At our AGM, Keith outlined our plans for trips and visits this year.
Top of the list is a proposed trip to Bletchley Park. Although not directly associated with astronomy, the place it holds in British history and the development of technology tickled the interest of HAS members.
We are also hoping to include a visit to Henley Boat Museum to see their Space Vault Exhibition. This exhibition incorporates rare and historic objects brought back to Earth from the lunar surface, low-Earth orbit and outer space, from NASA’s Apollo missions and the Soviet space era to the US and Russian space shuttle programs, International Space Station and SpaceX.
There's also The National Museum of Computing (TNMOC) in Block H at Bletchley Park - home to the world's largest collection of working historic computers.
There's so much to see that we plan a two day visit and will find somewhere to stay overnight nearby.
If you haven't already signed up for this trip, please contact Keith (here) to find out more.

That's it for our 2024/2025 season - the clocks have gone back and the evenings are lighter. Our next observing session will be the first one of the 2025/2026 season in October.
As always, look out for emails from Chris giving proposed date and details and look out for any last minute alterations. We will endeavour to stick to these dates unless weather means 'sliding' it, in which case it will likely be a few days earlier or later and members will of course be advised. Each date is centred on the first Thursday after Third Quarter.
If you are not on our emailing list, please contact Chris for the latest news - contact details here.
Remember that there are some great online observing guides - a good one is run by Telescope House. Look out for the monthly night sky emails from Chris.

Dr Steve Foulkes (HAS)
Many of our speakers at the Virtual Talks have allowed us to record and share their talks for society members to view if they missed the meeting. We've started a HAS YouTube channel here where you can visit or subscribe to and watch these talks.
To watch recordings of previous talks, they are on the "Recordings" page here.
Our last meeting was given by Dr Steve Barrett at the Kindle Centre - so we weren't able to record it as a Zoom meeting. However, Steve has cunningly managed to record the live presentation using his lap top:
A talk given by Dr Steve Barrett to Herefordshire Astronomical Society on the 3rd April 2025.
Steve is a Senior Research Fellow in the Department of Physics at the University of Liverpool. His research interests span all aspects of imaging, image processing and image analysis. This includes medical imaging (biophysics), scanning probe microscopy of atoms, molecules and surfaces (nanophysics), microscopy of earth materials (geophysics) and astrophotography.
For our April talk, Steve looks at space rockets - rocket science is thought to be hard because the maths of orbital mechanics gets in the way. This talk skips over the maths and looks at orbits, how spacecraft travel between planets and how they can park at Lagrange points.
Look out for emails from Keith with the regular FAS Newsletter and news and information about other events and talks that you may be interested in attending at FAS and other Astronomical Societies
Taken any astronomy photos over the last few months? Share them here with HAS members!
Take a look at what HAS members have managed to do over the years on our Images page (here).
HAS members have risen to the challenge of imaging all 110 Messier objects! Check out how we're doing on our Messier Marathon page (here).
Below are some recent images taken by HAS members:
Francis acquired these two images using a Askar 120 APO refractors (x2) dual mounted on an iOptron CEM 60 EQ mounting in a roll-off-roof observatory. NINA software controls the mount and cameras (asi2600MC Pro & Duo) with Astronomic UV/IR cut filters inserted. Thursday/Friday 2nd/3rd Jan '25
NGC 281, IC 11 or Sh2-184 is a bright emission nebula and part of an HII region in the northern constellation of Cassiopeia and is part of the Milky Way's Perseus Spiral Arm. (Wikipedia)
The Horsehead Nebula (Barnard 33) is an iconic dark nebula in the constellation Orion. Along with the nearby Flame Nebula (NGC 2024). Active star formation is taking place in the dark cloud of gas and dust of the Horsehead Nebula. The distinctive red colour that you see in photographs of the Horsehead Nebula region is due to the ionized hydrogen gas (Ha) sitting behind the dark nebula. (AstroBackyard)
Here's a first image for HAS from new member Steve - who has been imaging for many years. This image has shown Steve's expertise in processing data - both highlights and faint areas have been brought out beautifully! Steve used a 6" refractor in his own back garden observatory:
The Orion Nebula (also known as Messier 42, M42, or NGC 1976) is a diffuse nebula in the Milky Way situated south of Orion's Belt in the constellation of Orion (Wikipedia)
Francis took these two fabulous images below on New Year's Day evening. Francis used his dual imaging rig with Askar 120 refractors and field flatteners to give an 840mm focal length. He says he took 2x 300 second exposures for Thor's Helmet and 50x 300 second exposures for the Helping Hands dark nebula:
NGC 2359 (also known as Thor's Helmet) is an emission nebula in the constellation Canis Major. The nebula is approximately 11.96 thousand light years away and 30 light-years in size. The central star is the Wolf-Rayet star WR7, an extremely hot star thought to be in a brief pre-supernova stage of evolution (Wikipedia) .
A group of dark nebulae (LDN 1355, 1357 & 1358) together form what looks like an outstretched helping hand. Located in the constellation Cassiopeia.
The Heart Nebula (also known as the Running Dog Nebula, Sharpless 2-190) is an emission nebula, 7500 light years away from Earth and located in the Perseus Arm of the Galaxy in the constellation Cassiopeia. It was discovered by William Herschel on 3 November 1787. It displays glowing ionized hydrogen gas and darker dust lanes. (Wikipedia)
Van den Bergh 152, also known as Cederblad 201, is the blue reflection nebula on the end of the dark "shark" nebula. The large dark nebula stretching through the image is a Bok globule. This complex, designated as LDN1235 (Shark Nebula) and Barnard 175 (Wolf's Cave), is located about 1,400 light years away in the direction of the constellation of Cepheus.
Once or twice a year, members like to jump in cars or climb in a mini-bus and make their way to go and see something interesting outside of Herefordshire (passports not required - so far). Previous trips have been to the Spaceguard Centre, the International Astronomy Show, the National Space Centre, Jodrell Bank, the Norman Lockyer Observatory outside Sidmouth, the Herschel Museum in Bath and the Hanwell Community Observatory just outside Banbury.
At our September meeting, Keith described the potential sites we could visit and took a poll of those present. Based on your feedback we've now had a fab trip to visit to the Spaceguard Centre in Knighton and Keith is now looking to organise a longer visit to Jodrell Bank in 2024 with an overnight stay to make the travel easier.
Look out for emails from Keith explaining more about the proposed visits and asking members to register for the trips.
Our next proposed trip is to Bletchley Park. Although not directly associated with astronomy, the place it holds in British history and the development of technology tickled the interest of HAS members. We are also hoping to include a visit to Henley Boat Museum to see their Space Vault Exhibition. This exhibition incorporates rare and historic objects brought back to Earth from the lunar surface, low-Earth orbit and outer space, from NASA’s Apollo missions and the Soviet space era to the US and Russian space shuttle programs, International Space Station and SpaceX.

We've set up an online community for HAS members where you can raise questions, share your experience and suggest topics for talks or visits. We've created a discussion group on the Groups.io platform. This is a "fremium" based platform and promotes itself as "We don't run advertising and your data is never submitted to any ad tracking networks.". There are a lot of other astronomy and expert groups using this platform - it looks like a safe place to be online.
We've set the permissions for the group to be listed publicly but content is private - only HAS members can see what you post. We are moderating new members joining the group to manage spam bots and spurious content. This means new member requests have to be approved by an Admin before being admitted to the group.
Once admitted you can follow discussions and post entries. It's an email based platform by default - you'll receive new posts by email from other members. However, if you don't want individual emails you can go online and change your "Subscription" to turn off emails and receive digests etc.
Have fun!
