Please contact us if you have questions regarding Daytime or Evening group visits.
Due to COVID-19 there have been changes in-line with Government guidelines.
Please contact us if you have questions regarding facilities at The Observatory Science Centre.
As with most place names there is a 'correct' pronunciation amongst local people and Herstmonceux is no exception.
Herst is the Saxon name for a wooded hill, and the manor is mentioned in the Domesday Book as being part of the land belonging to the Count of Eu.
In 1131 the Count's grandson transferred the manor to Drogo de Monceux, (great grandson of William the Conqueror) who married Idonea de Monceux. Their son was known as Walleran de Herst Monceux.
To answer the question 'How do you pronounce Herstmonceux?'
This is always a difficult question.
It very much depends on where the star is and how bright it is. Many of the stars are far too faint and distant making it extremely difficult to pinpoint.
To avoid disappointment therefore we do not usually offer to locate such stars with our telescopes.
Do you offer a "star naming" service?
No we do not.
Some commercial enterprises do say that they offer such a service and will charge a fee for it. However such "names" have no formal or official validity whatsoever.
This is an excerpt from the International Astronomical Unions (IAU) website: As an international scientific organization, the IAU dissociates itself entirely from the commercial practice of "selling" fictitious star names or "real estate" on other planets or moons in the Solar System. Accordingly, the IAU maintains no list of the (several competing) enterprises in this business in individual countries of the world. For further information please visit the IAU website www.iau.org/public/buying_star_names/
Not at all.
Space telescopes fulfil a very important role but they cannot be made as large as ground based telescopes due to weight and the cost of getting them into space.
The wider the diameter of a telescope the better light gathering ability it has and the more detail it can resolve.
At the moment the largest ground based telescope is the Gran Telescopio Canarias (GranTeCan or GTC). It is a 10.4 m (410 in) reflecting telescope located at the Roque de los Muchachos Observatory on the island of La Palma, in the Canaries, Spain. It is the world's largest single-aperture optical telescope.
Although atmospheric disturbance is not a problem encountered by space telescopes, many ground based telescopes do have a problem and atmospheric disturbance can distort the image. However, adaptive optics used with large ground based telescopes can compensate for distortion caused by the atmosphere.
While the telescopes are not being used scientifically for research purposes they are open to the public on our open evenings which are usually held during the Autumn, Winter and Spring with one or two exceptions in the summer.
They are also open on our special themed evening events which take place throughout the year.
You can also hire the centre for private evening group visits when you may get the opportunity to use the telescopes (weather permitting).
Twilight educational visits or scouting and guiding group visits can also be arranged.
No, because if you catch the Sun it will blind you.....
Also daylight swamps the light coming from celestial objects making them almost impossible to see.
Not quite, Herstmonceux is 0.320 E of the Greenwich Meridian.
No. This is an empty building and does not have any public access.
The science centre is located within the estate of Herstmonceux Castle https://herstmonceux-castle.com/ but is a separate business.

If you want something different for your school, community or private group then a visit from our inflatable planetarium is a fantastic option. As a presenter led show, we can tailor our presentations to suit the needs of your group.
Our planetarium service is designed to be an interactive experience, led by presenters who are professional and adaptable. With backgrounds as teachers, scientists and astronomers: they will bring an immersive experience that will excite and enthral all audiences.
We send 2 people ensuring opportunity for Q&A, subject to your own timetable, and all have a Disclosure & Barring Service (DBS) Enhanced Certificate and many are registered STEM Ambassadors.
We offer a wide range of presentations covering a substantial amount of the curriculum in science from reception through to A-level.
As an interactive experience, session content is flexible and presentations can be geared towards specific learning objectives and curriculum targets. As a general idea, we can cover:
Key Stage 1
Key Stage Lower 2
States of matter
Key Stage Upper 2
Earth and Space
Key Stage 3
Key Stage 4
Forces and Motion
Each presentation lasts approx. 30 – 45 minutes, depending on your schedule.
The whole experience will include pre-presentation points, entry / exit, and questions.
The dome can be set up in any indoor venue space such as your hall or gym, and taken down at lunchtime if required. Please ensure your timetable gives sufficient time for disinfecting protocols.
Please see “Our Domes” page for dimensions.
We need to unload / load our van as close as possible to the venue. Please inform us at the time of booking if there are any parking issues at your venue.

If the presentation area is on an upper floor then a lift is required for moving the equipment.
Presenters cannot move large items or clear the space when they arrive on site, so the floor surface needs to be cleared, clean and dry prior to our set up.
At end of the visit presenters will ensure the space is left as they found it.
Unloading and set up of the planetarium takes approximately 40 minutes, with similar time required for pack down and loading.
There should not be any other activity in the venue space during set up / pack down.
Presenters will do their very best to supply presentations to fit your schedule / timetable as arranged at the time of booking.
Additional time will be required during the day if the planetarium has to be deflated and cleared for pupil lunch requirements etc. so please factor this into your schedule.
