Milky way bulge around Laguna

[rotatux]

I have been suffering too long from bad weather, so I'm a bit rusty at AP. Any way this challenge is an excuse to post the only nice something I could get recently (taken on 2019-08-29).

I like that region, it's rich with emission and reflection nebulas, open and globular clusters, and even a planetary nebula (though you can't guess it in the photo). It's also about the lowest I could shoot at the milky way this season, without getting too much light pollution.

From middle left to upright through center: Kaus Borealis (star), M28 (glob), M8 (laguna), M20 (trifid), M21, M23 (open). Also some minor globulars SW of laguna can be guessed as fuzzy stars.

Very nice image, like that.

Lovely tight stars, lens is very nice. I like using the canon 85mm f1.8 though I stop down to f4 as that gave a better result on CA, does your samung lens suffer from CA or is f2.8 enough to control it?

Yes fantastic lens, not only for AP, it's also a killer for portraits

I have "lab" tested that Samy and there's a bit of CA and coma wide open at f1.8 in sides and corners, but it's not a lot, rather like what remains after closing 1 or 2 stops most old manual lenses. It's just that for 1st light I didn't want to waste the shot and closed to F/2.8, which is enough to control it as you see.
