The Geminid Meteor shower is due on 13th -14th December, it's an annual event in the astronomy calendar. Apparently the show starts up to a week before and tails off during the week after so if the appointed night is clouded over then there are other options. The peak time to view is about 2am no mater where you are located.

Along with my attempts to capture moonlit landscapes I want to try to capture more meteor showers if I can. I am fortunate in being only a few minutes drive from several high vantage points which don't suffer too badly from light pollution, so it's a good opportunity for me.

Not being particularly well clued up on astronomy techniques I did a search and this is one of the results I came up with.

This evening is forecast clear, so armed with my recent experience in Glenridding and the info in the link above, I plan a sorti this evening. There will be no moon tonight given it sets at about 2pm this afternoon, so it should be a good, clear, dark sky.

I am going to try for a star-trail image with one camera and set one of the cameras up with the intervalometer set at 40 second intervals making 30 second exposures at perhaps f5.6. Experimentation required!

Given the CA issues I experienced recently, I plan to avoid wide open apertures. A couple of years ago I took some Perseid meteor shower photographs so I will take a look at the image data from them and use that as a guide.

This is one I caught of a Perseid meteor in August 2009, well, I thought it was a couple of years ago!!! Time flies when you are enjoying yourself...
