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.

Yep.. seems good!

• Canon EOS R5
• RF24-105mm F4 L IS USM
• 24.0 mm
• ƒ/4
• 15 sec
• ISO 800

Here's a slightly easier one too, using the f11 'trick'

• Canon EOS R5
• RF100-500mm F4.5-7.1 L IS USM
• 500.0 mm
• ƒ/11
• 1/400 sec
• ISO 400

@Kevin.sim maybe your lens needs a firmware upgrade to work better with the R5. I know my Sigma needed one.

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.
If you don’t have it yet, there is a great phone app called Photo Pills that computes the NPF rule and lots of other invaluable items for Astro.

Yes that is the one I was alerted to and am going to try. Thank you!

I was really happy with it shooting the Milky Way, this was a quick night out to get ready for an upcoming trip. Image was a stack of 10 images, used Sequator to remove noise, shot with R5, Rokinon 14mm 2.8, manual Focus at f2.8, iso 3200. Processed in Luminar AI.

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.
