Not to sure, this last image looks a little out of focus. Stars look to big and bloated.

Nice images. I think that focus was ok, but you have trailing stars. Were these taken with a fixed tripod? To get more colour you would ideally need more exposure and a tracking mount.

When you get star trails, the light from a star is smeared out over the trail, instead of being concentrated in one place. This makes images dimmer.

What equipment did you use?

It was a fixed tripod with a Nikon d3300. I'm still thinking about purchasing a dovetail camera mount to attach it onto my alt-az goto mount.

You will get longer exposures if you can mount it on your alt-az, depending where you point your camera in the sky you might get 45 seconds.

Very nice pictures!

Interesting link that shows you where in the sky you can get the longest exposure: http://autostarsuite.net/forums/storage/19/4981/field rotation v3.pdf

Its very technical, but if you read it a few times, you'll find out where in the sky you can go how long (in theory).
I received this link once when i posted in this forum about max achievable exposure times with alt/az.

Kind regards, Graem

Nice images, a touch of "curves" will bring out quite a bit more detail.
