Canon 5D4 24mm@2.8: 8s ISO6400
Processed in Lightroom Express (iPad)
Hopeless at any sort of post processing, but find LRE quite straight forward! Have a set of these, that I will attempt to stack and post shortly, but any tips of this image, gratefully accepted.
The skies in Gove are pretty special. Im lucky to get out there 3-4 times year for work.....I try to plan it for the new moon.
I don't have a portable tracker, so 8s is about it before some trails. But the 5D4 is still ok at ISO 6400.
I have about 10 images to stack, but not sure when the point of diminishing returns kicks in for number of subs. Also at 8s subs, not sure if stacking will increase signal significantly, it should be a bit cleaner though....but as I say im pretty clueless when it come to post processing.
The point of diminishing returns with most images is waaaaaaaay more than
the 10 subs you have. Many people [ cometcatcher for example] routinely
use hundreds. I mostly used 50-75.

Hi Hemi,
Actually, you can get more subs than you think; as your target drifts
across the screen after each sub, DSS will align each next one with the previous one. So, if you start with your target say 25% off centre against the direction it will move, and keep shooting until it is about 25% off centre on
the opposite side of the screen [or viewfinder] you will get quite a lot of subs.
Incidentally, a 50mm lens gives round stars for about 9-10secs for a target
on or near the celestial equator,[using a static tripod], so you should be safe
doing 15 secs with your 24mm. In case you didn't know, as you move away from the C.E. you can increase the length of your subs quite substantially.
