Trifid and Lagoon nebula

A stack of 19 frames (and 2 darks) of the Trifid and Lagoon nebula. Taken with a Pentax 1 using the astro tracer function and Tamron 70-200 lens at 200mm, 10 secs, f2.8 iso 1600. Stacked in StarstaX. Photos taken on La Palma island which at nearly 2,500m elevation has fantastic night skies.

Brilliant photo, taken in one of my favourite places.

Impressive. How many years had those photons been travelling before they hit your sensor??

Pretty good. But there is no need to use the lens wide open and have huge ISO with the Astrotracer. Stop your lens down to f4 or even 5.6 and there's no need to go above ISO 800. Also at 200mm you should get 60 seconds at least with no star trails.

Beautiful colours!

To improve from here, make sure you're using a very solid tripod. I don't think the trails are due to star motion. They could be caused by the movement of a tripod head (had this issue once and I wondered why my exposures had streaks).

Set your lens to f/3.5 or f/4 and it'll be sharp enough. Increase exposures to 30 seconds safely while keeping the ISO at 1600 or maybe drop to 800 for a little more colour detail.

Thanks for the helpful comments. This was a quick grab whilst doing Milky Way shots and timelapse with my other camera body. Previously I’ve managed to get 4min exposures with astrotracer and a 20mm lens. For this shot I used my second (travel) tripod and maybe this did contribute to inability to get long exposures

Wow, excellent image, particularly with a non-astro setup (i mean no eq mount / big telescope)! Love the colors and the deep blacks

Excellent photography.

Best regards
