Urban Astronomer
Welcome to The Urban Astronomer, an astronomy website written for and by people who are trapped in the city and denied seeing the full glory of a dark night sky. Here you will find articles on how to set up an observing site to minimise the effects of light pollution, and guides on how to get the most enjoyment from naked eye, or small instrument viewing. There are more detailed articles explaining the science behind common astronomical concepts (from Eclipses to Black Holes). There's a question and answer section (now with a Short Questions sub-section, for the researcher in a hurry), where I answer reader's emailed questions with full length articles, and a News and Updates section, where I'll post short news items, and announcements of updates to the site. There's even a 2012 section, where I attempt to cut through the fog of doomsday misinformation around the year 2012.

ATM diary

  • I'm back, baby! At last, I've got grit under my fingernails and fingers that can no longer operate a capacitive touch-screen phone (Seriously.  3 hours of exposure to silicon carbide, ground glass and a detergent-glycerin-water mixture have done something weird to my fingers so that my phone no longer thinks they're human.  ooooh.....), and as a bonus I moved on to the next finer grade of abrasive!So I arrived at the class this afternoon, dodged a thunderstorm getting my mirror making kit from the car to the workshop, and ran into an immediate problem:  I didn't know which cannister of abrasive to open.  See, I keep all the sponges, salt-shakers and grit containers from each ...

  • New beginnings Hello?  Anybody still reading this thing?  If you've given up on me and my project, I couldn't blame you.  Things have been pretty silent for a long time now, for reasons I've gone into in more than enough details previously.  However, over the coming week I'll be unpacking my mirror, reclaiming my bucket and spray bottle from the housekeeper's cleaning cupboard, and preparing to pay a visit to the ATM class this saturday.  Meanwhile, I'm hoping to put in a few more hours (and finish my stash of #320 grit) to get that mirror free of pits and subsurface fractures.  Watch this space!

  • The telescope making class, now on TV I haven't been to class in a very long time.  So long that I couldn't say if it was even still running!  Fortunately, they made an appearance on the Afrikaans language magazine show Pasella, to a national audience, which confirms that they've continued operating as normal, even while I languish at home (and at work, and in exam halls, and...).  If you'd like to see some of the faces who've done their part to instruct and motivate me, watch the segment below:
