star gazing on the downs!

Cool shot.  What kind of exposure time and aperture to do these kinds of shots?  Special filters?

For star trails you need:

*  dark skies
*  lots of patience
*  a camera that will go to bulb,
*  a well charged battery, and
*  an interval exposure device is good. 

This one is 10 - 15 minutes, from the length of the trails.  I usually use f8 but it is trial and error.

The other method is to use the interval timer to do multiple 4 min exposures and stack them using photoshop.

The result is like the one on the front of this book, which is where I learned about it - great book and I recommend it.

We would also suggest a simple google search as there is a wealth of info there suggesting anything from F4 @ ISO 1600 @ 30 seconds to F8 as Odille suggests! This one was actually 37 minutes @ F8 ISO 100. The main aim is a bit of fun and the more you play with it the better/easier it is!

PS - personal recommendation is a spot that also allows a couple of steaks on the BBQ and a glass of your choosing while you wait!!!!!!!!!!!!

I have bulb mode on my camera, and it was awesome for taking fireworks shots.  However, I have to hold the button down for the shutter to stay open.  How can I get around that?  I have a Nikon D60.  Would this work if I had the wireless remote control accessory?

I have a remote cord that has a device at the end that lets you lock it in place for the length of the photo.  You just slide it up.  I have one for the canon and one for the hasselblad, so you can obviously get them for all models.  I bought mine on Ebay, search for remote release then sort by camera brand.  It's not strictly remote as you are connected by a cord.  You have to time the exposure manually.  It is better than holding it down as it eliminates finger shake!
