We considered moving to La Palma when His Nibs retired.
Didn't happen, but still our favourite island.
I am surprised you were allowed to be up by the telescopes at night. The road is normally closed at dusk to cut out any risk of light polution.

Nice to see a touch of airglow as well.
Thanks for the comment. La Palma is certainly our favourite island for Astro. The road is closed an hour before sunset. But you can park on the main road and take the signed footpath behind them at night. Just your headlamp down. Will post some photos next week

This summer we spent 2 weeks on Tenerife and La Palma in the Canary Islands. These are fantastic locations for the night skies. Of the two islands, La Palma was our favorite. It's less developed than Tenerife and houses the fantastic collection of international telescopes which provide great backgrounds for timelapse and astro photos. We have produced a short video of timelapse photos and I'll post some still photos soon.

All the timelapse frames were taken with a Pentax K1

Sterennow (stars). The Milky Way above Greenburrow engine house at Ding Dong Mine, Cornwall. This a composite of a foreground shot illuminated by moonlight and a single 4 minute exposure of the night sky. Uniquely the Astrotracer function of the Pentax K1 allows for such a long exposure in a single shot at a relatively low ISO of 800 which gives sharp details of the stars without the noise present using other cameras with a much higher ISO

I also shot the night sky without the astrotracer using ISO3200 and a 30 second exposure. An extract of this is shown below, along with an extract from the 4 minute astrotracer shot. The 30 second shot is a lot fuzzier, noisier and shows less stars than the astrotracer shot. The stars do appear bigger in the 30 second shot, presumably due to star trailing. The 4 minute exposure was also taken using a super sharp Pentax 15-30mm lens and the 30 second exposure with a Samyang 14mm lens

Great shot.

Incredible result, well done. How long was each exposure? I've only been getting 10 secs with astrotracer lately using a 70-200 lens.

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

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.
