Originally posted by SunValley Very neat presentation, your nightscapes are really really good. Seems it would be a fun presentation to watch. The only thing I didn't see in your presentation is how you go about actually stretching your histogram and how you make those nice colors pop like that but depending on your audience you may not want to go into that much detail. I'm also curious as to why you don't use the astrotracer instead of stacking?
So Astrotracer has issues with very wide lenses. The edges will streak while the center will be good. My current nightscape lens is the Pentax 15-30.
For instance, I tend to take 13 second shots for my images when I do a single shot or stack.
If I do Astrotracer, I can get close to 30 seconds before the streaking becomes an issue. I have done smaller stacks w/ 30 second shots using Astrotracer.
But not a 5 minute shot at ISO 800.
I plan on this winter to shoot Orion and the Pleiades using a 135mm lens and will use long Astrotracer shots to see how that works.
