Blending foreground and background in milky way landscapes

[nmoore6]

Hi all,

Wasnt sure if this was the right place to post this, but Im new to nightscaping, and had a question. Im learning the ins and outs of photoshop and lightroom. I have taken some shots of the milky way that, to this point, i have been happy with. But id like to learn how to do two separate exposure of the foreground and milky way so i can get one of those awesome shots where everything is in focus. can anyone explain in simple terms the way to blend two images together to achieve this?

 

Thanks!
