Subject: Perseids summary image 11/12 August (22 meteors)
Here's a summary of all trails imaged on the night before maximum. The
two b&w images were taken with a CCD camera fitted with a 28mm f/2.8
lens. The system gave me a field of view approximately 10 degrees
across. The last image shows a pin-point meteor very close to the
radiant position (as it should be of course!).

The two central images in the second row show a glow through Taurus. I
believe this is the Zodiacal Light but I'm currently seeking an
expert's opinion on this one before I post up the full frame images.

The summary file contains 22 meteor trails and is just over 1Mb in
size.

Thanks for the info, Pete. It seems like the radiant point
ought to migrate but I lost touch with it.

Excellent images Pete with a crafty leaning toward
composition.

Where is the radiant point of the shower? I always thought
it was in that little circlet of stars ESE of Mirfak near
Lambda Perseii and NGC 1528 but when I traced back every
bright Perseid I saw it seemed to coming fron a point between
Eta and Gamma.

The radiant moves considerably throughout the activity period of the
shower Ben. On the night of maximum draw a line from gamma to eta and
turn left by 90 degrees. Move by the gamma-eta distance again and
that's where it lies.

Very nice. I wish you had a grating to put on your camera, to get
a few meteor spectra!? Ever thought about it? With your skill
it would not take much. If you were closer I would give you a
full ap grating for your camera.

I got all packed up here then clouds moved in Sunday. Never fails.

Here's the summary image for the maximum night (12/13 August). I've
still to do a fine sweep of all the images taken but that'll have to
wait for a bit. Total number of meteors imaged over two nights: 47.

Superb!

I only saw a few as I had only just finished having dinner at Rick Steins
Sea Food Restaurant in Padstow. So made a quick dash across to the harbour
to have a peek.

Well done again Pete
