Thank you Carole.  I had planned to get a lot more time on this but 'Cloudy Nights' were many.  Yes I took a mount and telescope; the mount and tripods went in the with the hold luggage (a 25kg bag) and the rest either went in my cabin bag (10kg) or backpack (not far off 10kg) - quite a weight in all.  Last time I went to Tenerife I took the AM5 and Samyang but this time I took the smaller and lighter AM3.

When the skies were clear they were great but nothing is as unpredictable as the weather!

Envy envy.  I tried to image this from DSC but didn't get much time on it and it's not a patch on this one.

Great image especially for just over 2 hours, just goes to show how good the skies are out there.  Wow you took a telescope and mount with you.

This is an often overlooked faint dust and reflection nebula in the constellation of Scorpius.  It is very near the more colourful Antares nebula to the south east.
 The nebula is bathed in blue light from the star Nu Scorpii (Arabic name Jabbah).  The nebula is actually quite bright at magnitude 3 and about 420 light years from away.  Documented size is 150 x 60 arcmin.

Airglow Blasts over the Dolomites

On a trip with friends to the beautiful Dolomites mountain range this past autumn, while observing the night sky, we experienced the craziest and strongest airglow I had ever seen. Structures were clearly visible to the naked eye, reminding me of cirrus clouds. But of course, the sky wasn't cloudy at all. Rather, airglow is the natural glow of the Earth's atmosphere -- it forms in the lower thermosphere.

Thanks Carole.  It would have been a very difficult without recent tool developments.  I'll try and find some time to do it a bit better when back in the UK (I was tired and had a small screen with silly pixels when I did this).

Yes Carole it was one 2 second exposure with the camera on a tripod.  SQM reading overhead was 21.9 at the time but not quite so good where the exposure was taken.
