The other thing is the VW was copied by Dr. Porche from the Skoda with the flat four air cooled engine. CHEERS Vic.

Listings like this are great reminders why I don't much like people.

I have a pentax K20d and want to do some star trails........... rather than having 1 x 60min exposure, I want to do someting like 80 x 25 secs with a small interval in between........... less noise - less light pollution etc - and then stack in Ps.
any help much appreciated
Use anything under 8 secs and you'll probably not pick up sufficient star detail, too long an exposure and because of the DFS you'll have dotted lines for star trails. Long exposures were the reason I kept hold of my K10D after 'upgrading'
Hopefully someone can come up with something more constructive to help solve this.

If I had one comment to add it would be that there's a slight lack of variety - next time perhaps a bigger range of focal lengths, some shots with a wider aperture, slower shutter speeds etc will give you a more 'complete' set of event pics. These will come with practice and experience, so keep at at!

concerning weather is it a complete no no to shoot in any sort of rain ?
Don't discount the 18-55 WR either, if you can get close enough to the track a wide angle can work wonders too - not motorbikes, but shot with a Sigma 10-20 at the wider end:

I was hoping to use my tamron 70 200 f2.8 on k5
Aperture-wise it depends what you mean by 'small'. Remember that a small f-number actually means a larger iris opening. Put simply, the lower the f-number you use, the more critical focus becomes. This is especially true if your working distance is quite small, i.e. your subjects are whizzing by pretty close to you.
f8 is generally quite safe, f5.6 okay and you'll notice anything less than that becoming increasingly tricky. Take a look at the exif data of some shots you like and see what effects the varying apertures have.
As for shutter speeds, aim to keep your shutter speed high, 1/250 or faster at first, then as you feel more comfortable begin to vary it and experiment some more.
Good luck and let us in on the results, the K5 is a much better tool for this than any previous Pentax DSLR

You either need to make your camera more sensitive to light (high iso), better able to gather light (slooow shutter speed, wide aperture) or create some light of your own (torch/flash etc) - perhaps a combination of the three, depending.
