Aurora not cloud

How wrong can you be, the weather forecasts all indicated a cloudy night, yet in reality it turned out to be a virtually a clear night. This was in the south mainland while the north mainland, Yell and Unst suffered with thick cloud and drizzle.



We headed over to the west side as it became dark just as the Aurora stats started to become better, rising wind speeds and density with the BZ on the down.


The moon had also set earlier in the night so it was very dark just the right condition to see the many millions of stars.


As well as the Milky way green airglow could be seen , something that confuses people as sometimes they think it could be the Aurora, but this was facing south not north.


However looking north the Aurora was bright and around 10.15 it became slightly more active with green pillars moving across the green band. This was only a  KP3 but being so far north it was a good show.


Around 10.45 the cloud started to arrive so we headed home well pleased.

With now well over 1,000 members Shetland Aurora Hunter has grown well since I started the group back in December 2016, just send me a request to join.


I had one of my Aurora photos from the 8 September published in the Shetland Times last week. It was rather a disappointing quality, but this wasn't unexpected as it is always a difficult subject to reproduce.

Recently I have had a couple of Canvas prints done and they have come out well. The Sony A7s only has 12 mp but they managed to produce good prints at 30x20 inches. Metallic paper and Acrylic are other  good options.

I have had numerous questions about processing, some don't like any type of enhancement except sharpening. A lot of Aurora photos for me are too dark so it is important to make sure that the histogram is about 1/4 way from the left, it is worth putting the ISO up to gain a lighter photo which usually shows less noise- noise lives in dark places.
