This is what happens when an aurora photobombs your comet imaging session! Nice show though.

Very pretty light pollution! I was watching this on Denis B's auroracam from just across the Moray from you. The comet was bright enough (just) to be detectable on that camera. It only has a 4mm FL lens. Here's the image.

Thanks Nick. Should there be a link to Denis's image? Ta.

The word "image" should be highlighted. Just click on that to get the image from Tarbatness.

Yes, that works. Thanks. I hadn't noticed the subtle highlighting on my monitor.
