I have found these links helpful.
- Sydney City Sky Watchers – Astronomy interest group, meets monthly at Sydney Observatory, a part of Powerhouse Museum
- Extravision, a retailer of diverse optics, in their “scratch and dent” list they sometimes offer spectacularly good value on discontinued lines, obsolete models, or cosmetically damaged items.
- Quasar Publishing, these guys produce a really good astronomy annual. I went to school with Glenn Dawes.
- Space Weather Gallery An online astronomy photo gallery, I occassionally post images here.
- Grove Creek Observatory – Online Telescopes, I like this idea.
- I am developing a website dedicated to “All things Raspberry Pi” – the ultra cheap computer for geeks http://raspberrypi.education/
