Just like on your super tele, the lens will focus past infinity so you have to find infinity focus. Now comes the task of finding better locations that offer nice scenic images and are far enough away from city lights to be dark enough.ġ. So what is done differently with each frame to make this stack a better image? Is it different exposures like HDR? Do you using stacking software like Photoshop or Helicon Focus, or is there some special sky stacking software? Can I assume that this would be less noticeable with a 14 or 15mm lens than with the 24mm?Ħ) Lastly, I see that many Milky Way or night sky images are stacks of 10 or more files. I also found the auto white balance to be all over the map from one frame to another.Ĥ) I found it extremely difficult to level the horizon by using the viewfinder (like nearly impossible) do people use Live View for this? Is there a technique for this? How do you frame your image when it is so dark and hard to see?ĥ) Even at 20 to 30 second exposures, there is a noticeable amount of blur and Earth rotational movement.

Yes I can fix that in RAW conversion, but was wondering if most people set a manual white balance, and if so, what K do you set it at? Somewhere between 4000k and 4400k seemed to be reasonable. So how do you manually focus the lens to be as sharp as possible on the stars?Ģ) Do most of you that do this use some kind of star tracking device? If so, what are some that I could look into that are not too expensive?ģ) Using "Auto" white balance I found the images too be too orange or warm for what it really looked like. My hopes are to get an Irix 15mm f2.4 at some point for this.ġ) I am realizing that just putting the manual focus on the infinity symbol is not accurate enough. FWIW, I am using a Nikon D810 with a Sigma 24-35 f2. I have read a bunch of articles online about it, but still am unsure in a few areas. It was my first time doing this and it was somewhat successful, but also opened up a bunch of new questions. Last night I finally drove about 50 km north of the city to find a location that would be dark enough to try and photograph the Milky Way.
