Hi and welcome to the 7th episode of the Urban Astronomer Podcast! This episode was dropped in the middle of the Easter weekend, so in deference to the season we’ve got a brief segment based on one of Urban Astronomer’s religiously themed articles: How is astronomy used to calculate the dates of religious festivals? And our feature item is another interview! This time around, I managed to get a hold of Neil Viljoen, who owns Telescope Shop, one of the … Continue reading →

Welcome to the Urban Astronomer podcast.  For the third time in a row, you’re getting a show in a totally different format from before:  This time, it’s a recording of one of my public lectures on astrophotography. In this case, it’s a talk I gave to the local chapter of Mensa, the world-famous high IQ society.  I had gotten to know one of their officers a few years back when we were on the same pub-quiz team, and she contacted … Continue reading →

Canon EF 50 mm f 1.8 II

One of my favourite tools for astrophotography is the Canon EF 50mm F/1.8 lens which I use for wide field deep sky images. It’s the single cheapest lens on the market, as evidenced by its all-plastic construction and the scratchy grinding noise made by its autofocus motor. But it’s also fast, small and light, and it performs way above its price range. It’s the perfect accessory for an astronomer on a budget, like me. Unfortunately, kids and photography gear don’t … Continue reading →
