so you achieve this with one shot when you say single exposure? tips if so please

There are two elements with taking astro pictures, the first is to have nice dark skies, which he appears to have. The second, is post processing - it's amazing what some people can pull out of images.
When taking an image, the light pollution in the area has a great effect on the length of the exposure. In dark skies, with some form of tracking, you may be able to take ten minutes exposures, whereas in light polluted skies you may only be able to take one or two minutes exposures before they become washed out, sometimes only 30 seconds.
Unfortunately, in the images above, his exif data is missing or blocked, so I can't help you with his exact settings. If you don't have tracking capability, you will be limited in exposure length by the size of your lens, ie.. you may be able to expose an 11mm lens for about 30 seconds before trailing becomes evident, while a 200mm lens may only give you 3 - 5 seconds of exposure.
I don't know if my response is helpful to you, wolfden, as I am by no means an expert, if there is a more specific question you need assistance with, please don't hesitate to post them, there are a lot of helpful people here, and surely someone will have the answer that you seek.
