This is the closest time to the images above. This one was taken at 01.44 UT from Maghera, N. Ireland and is concentrating on the western most section of the display. For now on I will try and take images every 15 min's after the hour.
15 mins after the hour would be even better Martin :-) And a very nice shot that is too!
Yes, the standard procedure for obtaining 'patrol' photographs is to point your camera at the brightest, most complex part of the NLC and make exposures accurately (to the nearest 15 seconds) on the hour, quarter past etc. However, with the now widespread use of digital photography it is a fairly simple matter to reduce the interval to say, five minutes, or, even 1 minute. My system, for instance, is set to 30 second intervals. Shorter intervals will increase the chances of obtaining matching sets and also allow the possibility of creating high definition time-lapse movies. I know that Canon DSLR's and some of the compacts can be controlled by programmable timers and/or software. I'm sure other manufacturers, Nikon for instance, include similar facilities with their cameras. Photographing NLC has never been easier or more powerful!
Multi station NLC photography is something we could easily collaborate on. All that is required is a basic set of 'ground rules' and I'd suggest a maximum 5 minute interval (ie, accurately timed at 5, 10, 15, 20.... mins past the hour) between shots with the camera pointed at the most interesting area of NLC, using a standard 50mm lens or equivalent. What do you think?
Sounds great Tom. The 5 min idea will greatly increase the chances of us all getting images at the correct time. I will keep this in mind for the next display which hopefully will be tonight weather permitting.
