Milky Way - from Utah MountainsPosted By Greg Bradley |
Hi Tyler,
Nice shot.
I think these sorts of shots are best done limiting to 20 seconds unless you are autoguiding or a short focal length lens, 50mm or less.
Star trails show up at about 25 seconds on 50mm lens or longer when there is poor tracking.
So if that same shot were taken with a 24mm lens at F1.8-2.4, 20 seconds would have been fairly bright and perhaps needed more shots to stack but it would have been pinpoint stars and you'd have more signal to process to bring out the colour more in the galactic core.
I think the guideline is short shorts under 30 seconds, 10 shots or more, 50mm or smaller, F2 for close to it for wide field Milky Way shots. Also noise reduction on and white balance set to daylight or perhaps measured from a photo of a G2V star (sunlike star).
The Nikkor 50mm F1.8 lens is a beauty but would be too zoomed in for that shot. So probably around 24mm size would be the one.
Greg.
