Nice, nice, nice!
Lovely wide field pic, Alex
Mate, just to be pedantic (
), you've forgotten to mention that your picture also include the globular NGC 6544 (to the bottom right of M8), the little open cluster BO 14 (between the Lagoon and Triffy), and another open cluster NGC 6546 (to the bottom left of M8).
This is the area of the sky that is No 1 on my Must Sketch list at the moment for my 8" f/4 dobbie. I can get a 3° TFOV, just a bit bigger than the FOV of your photo. Enough to also capture M21 as well. This is a terrifyingly BUSY scene. Nebulosity aplenty, stars, dark, light, swirls, lines, detail, detail, detail! Blooming gorgeous.
Great pic, mate
Alex.
