Hi David. It's a full manual lens with no electronic contacts so don't think it's an option. I'm still new to astro and learning that maybe a shorter shutter may be better to limit stars dragging over so many pixels. First I thought it was the lens but it performs nicely on my DSLR so I thought maybe there is a 'trick' with mirrorless.
It was just a thought. Good luck!
The high resolution of the R5 really messes with the old 500 rule. There is a complicated rule, the NPF rule, that is more accurate for computing shutter speed to avoid trails. With your shooting parameters shown, it computes to 11 seconds shutter speed for “barely noticeable trails” and only 5.5 seconds for true spot stars.
Yes that is the one I was alerted to and am going to try. Thank you!
I just posted a setting that I used and the results are a great starting point. So far the results on the R5 is great.
A couple things to try. Higher resolution cameras tend to out resolve lenses of a less quality. Not saying that lens is lesser I use one as well. It looks great 30mp and below. Details don’t pop with a higher res body. If you have photo pills go to the spot star calculator and use the NPG rule rather than the 500 rule. Last thing that NPF rule will drastically shorten your exposure time so pump that ISO up accordingly. Brighter higher ISO will be cleaner than darker lower ISO with a lifted exposure. Good luck.
