But generally, for Milky Way shots you would need:
A digital camera. No need for an expensive one.
Wide angle lens.
Tripod. The hardest thing to do is get focus of the stars. Can't touch the camera when it fires.
Remote switch to activate the shot, OR just have it on a delay. I do a 2 second delay.
I set my camera typically at:
F2.8
ISO 1600-3200
15-20 seconds exposure.
Then the timing of it is really key. You have to know WHERE the Milky Way is. You have to be in the "season of the Milky Way." Typically March -October for North America.
The Moon cannot be in the sky! It floods the sky with light. I use a phone app called "Photo Pills." It is just amazing. Worth every penny to know Sun position, Moon position, MW position, angles, and timing. You literally can know when the sunset will cross a certain building or structure on the day you look it up. Moon, too.
You have to be away from as much light pollution as possible. Hard to do, if not impossible to do on the east coast of the US.
I'm VERY jealous of the photographers I follow in AUSTRALIA!!! They get a great view of the Milky Way and have very dark areas. They don't know how to inflate Spyder tyres, but they can throw down a pint! LOL!!
Lastly, you have to get off of the couch and go take the pictures!
With all of this said, this is one reason why I bought a Spyder! It carries all of my gear easily and is safe to drive when I'm out in the dark. The only thing I'm worried about when I'm out in the dark by myself is a ZOMBIE APOCALYPSE and I can't get my Spyder started fast enough because of the damned safety card check!
