Today there was the chance to observe a total lunar eclipse here at Lake Constance! Under a clear sky and at about 28°C after 10 o’clock in the evening the blood moon was perfectly visible. Right below the moon planet Mars was shining brightly. A lot of people were interested in seeing this phenomenon.

Tonight I decided to image the Trifid nebula (M20)
which is quite “close” to the Lagoon nebula M8 from my last session. The seeing tonight was around ~2.4″ which could have been better – but certainly it was still sufficient.
Back in 2013 I already imaged the Trifid nebula with the same equipment but from Boeblingen. It is interesting to see the difference here.
For post-processing I used the free software DeepSkyStacker and GIMP. The full resolution images is available here.
Clear skies!
Tonight I was able to proof that the “Lagoon nebula” M8 was still there ~4100 years ago – wow! With a teapot, a sunlounger (probably better a starlounger) and the right music the night passed quickly 🙂
The total exposure time was ~1h36m. The seeing conditions were around 2.2″. It was a clear night without wind. I used my 8″ GSO newton telescope with an Atik383L+ camera (see here). And again I am amazed which image quality is possible with this equipment on this dark sky within this short exposure time. Below is just the luminance part of the image which shows some sharp details of the nebula.

It’s stargazing time on La Palma again – this time from Casa Las Flores. The little house is located in Aguatavar – close to Tijarafe on a height of about 580m. You have a power supply outside the building, free view to Polaris from both terraces and in July the bright part of the Milky Way is perfectly visible between 22:00 and 4:00 local time. Furthermore you have a coffee maker, a table, chairs, a fast WLAN internet connection and a barbecue. What else do you need? 😀
The image is a single frame recorded with an Canon EOS6D in combination with a Samyang 2.8/14mm lens (15 sec. exposure time, ISO4000) . The post processing has been done with rawtherapee.
Tonight I only test my equipment – for tomorrow I plan to record the bright nebula M8 in the milkyway. So stay tuned for the result!

Tonight I again spent the night at the Tacande Observatory on La Palma. There we observed the Coma galaxy cluster. The result is this photo taken with a modified EOS6D camera.
For post-processing I used the free software DeepSkyStacker and GIMP. The full resolution images is available here.
Clear skies!
