R5 and Astro

[Kevin.sim]

Wondering if anyone in the forum has done Astro shots with the R5 (night sky, stars/aurora). Just wondering if you're finding same results with lenses as you may have gotten with your DSLR? I'm still doing some testing with a Rokinon 24/1.4 but looking like it performs better on my 6Dii than my R5. Looking to see if this is common or to be expected.

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.

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.
