I'm really hoping someone can help with this one.
A little bit of background: Initially, I thought the issue was build quality of Samyang 14mm lens. However, I've now purchased a better lens and been to a dark sky site and taken some Milky Way images.
Equipment: Canon 200d, Irix Firefly 15mm F/2.4 lens, tripod, shutter release cable.
Settings tried: ISO 800-3200, shutter 20-25secs, aperture F/2.4-and various stops down.
Image 1: = F/2.5, 20.3sec, ISO3200

Issue: Stars are dashes (even in centre of image). This was the same issue with the Samyang (previously). I'm now struggling with why the Irix is producing the same results. Could it be the Canon 200d has a problem?
Note: I've also tried OFF/ON settings for each of the following (in different combinations):
Image2: = shortest length exposure taken: F/2.5, 12.5sec, ISO6400

It's a little better - but still has some coma when zoomed.
Much of what I've read suggests 30secs untracked for Milky way shots - but that's clearly not possible here - due to whatever I am doing wrong. So, how with <15secs do I capture enough to be able to get decent Milky Way detail?
Does anyone, have any ideas that may help me resolve this?
thanks

- Lens Aberration
- High ISO NR
