End of 2018 I visited the new Cherenkov Telescope on La Palma. Actually I planned to write a long article about this visit – but as it happens sometimes, other things are more important… I decided to skip this article since now there is sufficient information out there about this telescope. However, I think the images I took for this article are still worth to see and give an impression from the observation site on the Roque de Los Muchachos on La Palma. The following two links provide more information about the CTA on La Palma:
Some opportunities are very rare to come by. Sightings of certain species of birds are even rarer. For times like these, having a useful magnification tool such as a pair of good binoculars or a telescope can come really handy. In a broader sense, both, telescopes and binoculars serve the same purpose – they make an object that is far away, appear much nearer so you can examine it closely.
When you are observing birds from a safe distance, the birds don’t get nervous or feel threatened. You can enjoy watching the birds going about their activities without scaring them. Regardless if you are a novice or seasoned bird watcher, without a good magnification tool you are quite likely to miss out on priceless moments. Let’s take a look at which of these magnification tools is best suited for bird watching under various conditions.
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.
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 🙂
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!
