This is purely speculation, but here are two possible reasons for the warning about not using mono microphones

1. Having just had a look at the manual, the microphone socket can also be used to connect a cable switch. This probably shorts between two of the connections to take a picture, and perhaps a mono jack would continuously short and confuse the camera into continuously taking pictures? Having looked up the cable switch it seems to have a four pole jack plug, so I don't know where that leaves this theory.

2. The camera provides 2 volts to power an external camera. Perhaps a mono jack plug would short this voltage? Having looked at wikipedia, it seems as though a mono plug would short the righthand microphone power supply to earth:

That's probably why your mono microphone comes with a stereo jack plug.

So would I try plugging in your microphone into the K70? I'm not sure...

Anyone else got a better answer, or indeed tried plugging a mono microphone with a stereo plug into a K70?

It's good to see this is still being useful, and thanks a lot to Glyn for continuing to update it. It must have taken quite a lot of effort to track down and add in all the new subjects.

R o b.

The thing that puzzles me is the lack of a motion blur in the reflection of the bird. I can't think how you would see the one for the direct view of the bird but not in the reflection. Perhaps it is vampire motion blurring?

Yes, thanks Glyn for keeping this list alive. I had good intentions of continuing on with it originally, but it didn't happen. I'm glad there was someone else to take it on with more dedication than me...

Is it over photoshopped, or does it look like that because it's an infra red photograph?

Just in case anyone wants to compare and contrast, it looked like this originally.

We missed it. A friend phoned to say it was happening, so we went to rush out the door just as our new cat started vomiting. By the time we'd sorted that and got out of the city centre it was over...

Great photos by the way.

Next time...

The Lancaster University site didn't show anything other than "No significant activity" all night, but a friend of mine who lives in the countryside outside Aberdeen reports she saw the aurora last night and it was spectacular.

Here's hoping for tonight...

This Lancaster University site does current activity levels. They tweet warnings or it's possible to sign up for warning emails too.

My other half is really keen to see an aurura, and she's down south currently, so there's bound to be a good display before she gets back...

I'm hoping there'll be something still going on for Friday evening so she can finally see it.

Excellent shots. I was in the audience for one of the acts you photographed, if I've recognised The XX. We were near the back, so I didn't really get a good look at what was happening on the stage.

I didn't end up taking my Pentax SLR on site, but I did miss it from time to time, like at PIL. I enjoyed not carrying the weight round all day though.
