Great work man! Can we have some details about how you did the Milky Way shot please?
Cheers.
First off you need to find somewhere really dark. Much darker than where you could usually do star trails. Wait around 15 minutes for your eyes to adjust and then look East to South West I think. You will notice it if its dark enough. Just try not to look at any lights while you are doing it, I use a red torch for checking camera settings etc and have the LCD display on the lowest brightness setting.
Obviously set up on a tripod. Use the lowest F number available and set it for 30 Seconds. Could probably do a shorter with a nice 2.8 lens though. I did try with my 1.8 50mm but there is no focus points and everything came out wrong! I had my ISO to 1600. 3200 just pushed it a bit too much for my liking. I'll wait till I go FF to really push the ISO.
Whack it into Lightroom and have a play with the highlights, shadows, clarity and exposure. I had to drop a ND filter from the top to lighten it a bit and on one of the tree shots, I had to lighten the bottom.
