Got out on Friday night to shoot the Milky Way. I had from around 10:30pm until 1am when the moon would rise. I have been trying to perfect my MW pics for awhile and always shot on a 16mm due to the 500 rule. Now that I am using a star tracker though this rule no longer applies, so I shot with my 50mm. I also wanted to mess around with different f/stops instead of always 2.8 so I shot this one at f/3.5. from there I had to figure out exposure times and ISO. wanting to keep the ISO low for noise and get more of the colors in the MW, I started with 1000 but went up to 1250 then found that a shutter time of 212" was good. If I zoom in tight I can see short trails. this could be due to many factors: camera sagging on ball head, wind, not lining up north star correctly. otherwise the detail is pretty good.
I use the iOptron Sky Guider Pro
Amazon.com : iOptron SkyGuider Pro Camera Mount with All Accessories : Camera & Photo as my star tracker. The price is on par with others. what I liked about this one is the size and battery life and ease of use.
The location is the back side of an old abandoned dog track in eastern Colorado. It is 2 shots, one for the foreground and one for the sky. Then blended together in Photoshop
