So you must overlap a lot I take it. Is that to increase signal to noise ratio whilst at the same time developing a panorama?
I suppose you need to be snap and pop and get the photos done fairly quickly so they will stitch together without too much movement from the Milky Way.
Panoramas are my favourite type of DSLR imaging and I do a lot myself.
You have a great system going there.

Thank you very much once again Greg
You are right that the 14mm is a huge field of view in it's own right and I could easily cover this same field with only 3 or 4 images, but I take a lot more shots for my panoramas for a few reasons. It is not to improve the signal to noise ratio as you aren't really stacking them together you are more just using sections of each image. The main reason is to have a heap of overlap so that I have flexibility in what areas of each image I use. Also the super wide angle lens (well mine does at least- not sure about that awesome nikkor) distorts the angles of things particularly around the edges, so I like to only use the very center portion of the individual images. Coma distorting the stars around the edges can also be an issue. You are right that you do need to be reasonably quick but it's not entirely critical. I would have spent 15 minutes taking these shots and the star movement over that time is negligible in this field of view. PtGui Pro has no problems at all stitching them together.
Another reason for taking so many shots is to basically make sure you have the whole scene. I always take lots of data outside of the field of view that I ultimately want to capture so that it is easy to crop to where I want it. It's not unusual for me to have images with the tripod legs in shot.
Also, there is nothing worse than getting home and discovering that you missed a section of sky. These sort of scenes are generally one offs. You generally can't go back to the same spot with the same conditions like you can with deep space objects.
Hope this helps a bit.

Like Greg B, I am interested in your technique.
Thanks.

Thank you very much Marc
The smaller one on the left is Holbrook and the larger (but further away one) is Albury. They are pretty much directly south of me. The glow from Wagga Wagga (north) can be seen at the top of the first image "The Hanging Gardens". I do a lot of my shots around my local area.

Thank you very much for the great feedback Mike
You are right. With software like what I use (PTGui Pro) these sort of panoramas are very easy to produce and are somewhat a dime a dozen. I'm glad I could do something that stands out from the crowd.
Cheers
Amazing and beautiful. Thanks for the view.
