snigger....

Wide field shots on a tripod with shutter delays upto 15 seconds I would say.

Set to manual, set to mirror lockup and delay of 10 seconds. Put on tripod and set to ISO 800 and 'PRESS THE SHUTTER remotely'

Without a tracking mount you're pretty much going to be limited to wide-field exposures of up to about 20 or 30 seconds. At really dark sites this will be enough to capture some of the Milky Way and you won't get too much trailing of the stars. As you increase the focal length your exposure time will drop dramatically, and at 200mm you'll only be able to expose for perhaps 1 second before stars start to trail noticeably, (and 1 second won't be enough to capture anything but the moon and big planets!)

The moon won't look very big at 200mm, but have a play and I'm sure you'll be able to get something decent, especially if you can frame the image with a ground object.

G'day Matt,

Set your camera and lens for as wide as you can on bulb.

Put it on a tripod and point it at the brightest part of the milky way.

Set your ISO for 800

Use a delay, or use a remote shutter cable.

If you have 18mm, then use that.

Open your shutter for 30 seconds.

Do that ten times, one after the other.

Put the lens cap back on.

Take another ten photographs of 30 seconds (Yes, with the lens cap still on.)

Download Deep Sky Stacker. (DSS)

Load all the photos of the milky way, and all the photos with the lens cap on (called darks) into DSS. Fairly simple, follow the bouncing ball...

Click register and stack.

You will get a fairly grey image as a result of DSS stacking all the images together. Play with the sliders until it looks as good as you can get it.

Save finished file as a TIFF and enhance with photoshop, paintshop or GIMP. (Use curves and levels)

Congratulations, you just stepped into a larger universe.

For more, go have a look at my pages on how to...

Sorry but I honestly did not understand the question and if you had read further down the list you would have found that I am normally far more helpful when people ask questions. If I had of understood what you were aksing I would have linked you to several similar posts. Chill :-)
