Key features

LT Gravity plans the site by the Moon, as clubs do: the home page shows the month as one cell per night with the Moon in its phase and club nights ringed in red torch light. Pages cover planetarium shows with times and tickets, school and group visits, observing, dark-sky, moon and planet nights, telescope loans, membership and visiting.

  • A moon calendarEach night of the month shows the Moon's phase, and club nights are ringed in red, so visitors see when to come out.
  • Club nights set by the MoonDark-sky, moon and planet nights each get a page with where, when and what to bring, shown with the Moon that suits them.
  • Dome shows and telescopesA night board lists this week's shows and ticket prices, and the observing pages cover what the club telescopes show and loans.
  • Quickstart or template packageStart from a full copy of the demo site (the quickstart package of the Pro editions, restored with Akeeba Kickstart and Akeeba's restoration script in the browser) or add the template to a Joomla site you already run.
  • One-page mode (Pro)The Pro quickstart includes a one-page version of the home page: its menu scrolls to the home page sections, with smooth scrolling and the current section highlighted.
  • Change it without codeColours, fonts, logo, header and footer are Helix Ultimate template options; page sections are edited in SP Page Builder Lite.

What an AI assistant can do for a Joomla site

No AI writes into your Joomla site by itself. These are the honest options today; you stay in control of every change.

  • AI help in ticket support Available now with Pro Open a ticket and you get an instant AI-drafted answer; a person from our team follows up. Ticket support
  • Texts for your pages Works with any AI assistant Ask an assistant such as Claude or ChatGPT to draft your page texts in your own words, then paste them into the SP Page Builder text editor and your Joomla articles.
  • Small design changes Works with any AI assistant Describe the change and ask for CSS; paste it into Helix Ultimate's Custom Code tab and check the page before you save.
  • AI kit WordPress version only The kit that lets an assistant edit pages safely (instructions, ready prompts, a checked import tool) exists for our WordPress themes only. Nothing in a Joomla site is changed by AI unless you paste it in. See the WordPress version

Questions

Is it only for planetariums?

No. Astronomy societies, observatories and science centres with evening events can use it to plan visits around the sky.

Do I need SP Page Builder Pro?

No. The pages use the free SP Page Builder Lite, with Convert Forms Free for the contact form; Helix Ultimate is free too.

Quickstart or template package: which one do I need?

Take the quickstart package for a new site that should look like the demo. Take the template package to restyle a Joomla site you already have; your content stays and the demo pages are not added.

What is the difference between Free and Pro?

Free is the template package with the footer credit. Pro adds the quickstart package (a full copy of the demo, with the one-page version of the home page), credit removal and ticket support: Pro Standard for one website with a year of updates, Pro Unlimited for unlimited websites with lifetime updates.

What if it does not work for me?

If a Pro product has a problem we cannot fix, open a ticket within 30 days of your order and we refund it in full.
