Re: Wonky trail of 2004 BL86

For the benefit of others, I'm sure that Stella realises that it is highly unlikely for a 500-m asteroid to have a moon orbiting it with what would have to be a period of about eight minutes, which just happens to be the same as my periodic error! (They are 30 sec exposures with a 30 sec gap, and th...

Wonky trail of 2004 BL86

I got some shots of 2004 BL86 this morning at about 00.10 UT. I decided to use a 200 mm lens on my Canon 70D, driven on my HEQ5 but not guided. I thought that the guiding would be unnecessary in 30-second shots, but I was wrong. As you can see, the trail is not straight, which on the face of it is v...

Re: my first nebulae

You have answered a question that I've been asking myself -- can you photograph nebulae with a camera phone? Please give details of the scope! Presumably you just held the phone up to the eyepiece. The exposure details are embedded in the image -- HTC One phone, 0.14 sec exposure at f/2 (the camera ...

Interstellar nonsense

Should you not have seen it, my advice is that the plot of Interstellar is as empty of logic as interstellar space itself. Why so much money gets spent on filming with such a weak screenplay beats me. The most believable and charismatic characters are the robots. The story begins in an era some time...

Re: Astronomy accommodation in Cornwall

I made exactly the same point to Hannah when she first contacted me!

The postcode is EX23 9RZ but this takes you to a location some distance away. Here's a link to the correct spot:

Astronomy accommodation in Cornwall

While on holiday in Cornwall the other week I dropped in at Eddington Lodge, a new facility offering accommodation and telescopes for astronomers. The site is about five miles inland from Bude, near Kilkhampton, and is more or less on top of a hill so there are good horizons all round and light poll...
