Hi & Thanks Martin! As for the foreground, on that day it was foggy so the contrast between the sky and ground was much the same…  I take all my shots RAW because you have more play over them and still retain the detail, sometimes you can do what’s known as raw blend or on CS4 you can use the gradient tool while on raw editor and balance the sky & ground out.  You can also select the ground with the lasso tool and adjust the levels to brighten the ground up a little.  On Photoshop you can do most things to enhance the image, however on this day it was the fog that give the balance...

Hope this helps...  Grin

Thanks for the comments..

John, I second what Brian said and here is some info that i found on the lens..

Description - Nikon 10.5mm F2.8G ED-IF DX Autofocus Fisheye Lens
The Nikon 10.5mm F2.8G ED-IF DX Lens is targeted at Nikon DX Format digital SLR camera users who seek the unique visual effects a full-frame fisheye lens lends to landscape and other shots, to taking close-ups, or when shooting within vehicles or other tight interiors. Nikon 10.5mm F2.8G Lens excels at shooting extreme close-ups. Combining a minimum focus distance of just 3cm (1.2 in.) from the front of the Nikon 10.5mm F2.8G ED-IF DX Lens with Nikon's Close-Range Correction (CC) System ensures sharp results. The "Fisheye to Wideangle Transformation" function in the optional Nikon Capture 4 software package transforms diagonal fisheye images shot using the Nikon 10.5mm F2.8G Autofocus Fisheye Lens to ultra-wideangle photos, (by transforming the type of projection). This is an appealing new feature made possible only with digital photography and with the Nikon Total Imaging System. Optical and close-range focusing performance of Nikon 10.5mm F2.8G Lens are both optimized for Nikon DX Format digital SLR cameras. An ED (Extra-low Dispersion) glass element used in Nikon 10.5mm F2.8G ED-IF DX Lens minimizes chromatic aberration for clear, natural colors, and the rounded seven-blade diaphragm opening ensures a natural look to out-of-focus elements. This G-type Nikkor lens is designed with no aperture rings in Nikon 10.5mm F2.8G Autofocus Fisheye Lens. Nikon 10.5mm F2.8G ED-IF DX Lens operation is easy and virtually mistake-free because the aperture does not have to be set to minimum. The compact, lightweight design of Nikon 10.5mm F2.8G Lens fits comfortably in the hand. And photographers at all levels will be pleased with Nikon 10.5mm F2.8G ED-IF DX Lens outstanding cost performance.

Hi all!!! I know I have posted in a long time  Cry there were many reasons why I couldn't....  I have when possible been checking out the forum and I must say it is turning out to be a fantastic place to come and see, learn & chat with some of the best local and further a field fellow enthusiasts.  
As it says in the header "ISS"; I have been buying a few lenses and the images with this one is a Nikon 10.5mm Fisheye lens and I must say for the 1st time using it on night shots I am very pleased with it...
I went out last night and tried to capture the ISS on the 1st pass which was @ 20:15hrs. I took 6 images in all @ 30secs exposures, iso 800 @ f2.8 and have blended layers in PS3.

Are are some of the shots.
