Public open evenings

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.

Visitors to BayfordburyWhat 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.

27 March 2020


Due to the Covid-19 virus the University of Hertfordshire is cancelling all non-essential events, up until the end of April.

This means that unfortunately the public open evening on the 27th of March has been cancelled.

Refunds will be issued to all those who have already bought tickets.

Please accept our deepest apologies for any inconvenience and disappointment caused.

The view through the telescopes was a highlight. I would highly recommend this evening and I hope to make a return visit in the not to distant future.
