I see on some of the pictures it says astrometry. What is that and how do you use it?

This site does what is called plate solving: it shows you the objects on your picture :D

 

You go to this site: http://nova.astrometry.net/

You upload you picture, process it, when it's finished you click on "go to result" and you see this kind of image :D

Hope it helped :D

Nice images considering the short exposure time in the sub images. I know that more exposure time is required in order to show more detail in all object but this setup is obviously limited with no tracking.

Also I see that you use an IR cut filter on the lens to reduce the star bloat. Perhaps try using a uv/ir cut filter for the color fringing and to reduce the bloat even more.

Example images showing the difference would be nice.

What do you mean example images, it is a well known fact that a uv/ir filter helps a lot with star bloat and color aberrations.
