No problems Mick.. Registax is fairly simple to start with, but it can get more complex when you want to take advantage of more of the features, eg: wavelet processing. When it comes to that area, I just fiddle.

Iceman had a look at your wide field shots , there not that bad .
Is this your first attempt?
What you do need to do is remove the noise in the images and this can be done by doing a dark frame subtraction other wise good effort there.
I have a Minolta D7 digital camera with a 28-200mm lens that I have done some wide fiels shots with and am lucky because in bulb mode it does a dark frame subtraction as standard.
There are free ware programs around that will do this after you take a pic with the lens cover on.
You could buy a cheap eq1 , 2 , 3 mount with a motor and use this as a traking platform.
Wide field shots are quite spectacular I think , and a good and cheap stating point in imagery , although I am no expert , it is fairly easy to do.

Thanks Mark, the widefield shots in that section are my first attempt, just using the camera on a tripod. The camera has inbuilt NR for long exposures, but I usually remove even more noise by trying to stack several images, as well as running the final result through NeatImage.
I've definitely considered getting a cheap tracking mount for widefield stuff.. the alternative I was looking at also was to build a barn-door tracker, either manual with turning the knob, or get a stepper motor or something to do it for me.
I love widefield shots, I wish I could take better ones but atm i'm limited to 15s exposures because of the star trails.
