Public open evenings
-- Our open evenings are currently suspended --
Public open evenings are held at Bayfordbury Observatory around once a month between October and March.
Spaces are limited so booking is required in advance
What you can expect
During these events, you will:
- See some of our optical telescopes and, weather permitting, view interesting objects in the sky both looking through the telescopes and using powerful CCD imaging cameras.
- Meet the researchers, postgraduate and undergraduate students from the University's School of Physics, Astronomy and Mathematics
- See expert demonstrations.
- Attend talks on various astronomy topics.
- Talk to members of the local Hertford Astronomy Group
- Enjoy a tour around the sky in our planetarium.
These evenings are tailored specifically for the public so that adults, children and amateur astronomers alike can all enjoy the event.
If you have a group of 15 or more, please consider our private group visits which will allow us to tailor your visit to the experience of attendees.
Please note that the position and visibility of planets and the moon change throughout the year, and we may not be able to show you your favourites. This is unfortunately beyond our control. Only the very brightest planets, and a handful of galaxies and nebulae will show any detail or colour with an eyepiece, and therefore many of the telescopes will be equipped with sensitive CCD cameras to show you live images of targets that would otherwise be invisible to your eye.
- Adults: £8
- Concessions: £4 (students, people aged 3-24 and those with disabilities.)
- Children under 3 are free
Upcoming open evenings
Tickets are released approximately one month in advance of the Open Evening date.
Booking and payment is required in advance as spaces are limited and demand is high.
We have a range of staggered arrival times to manage parking. Visits are expect to last no more than 2 hours.
Booking is online only and we cannot take payment on the door.
We have no upcoming events planned
