Once more back on La Palma / Spain. I imaged the Milky Way a few times before from this beautiful location. However, up to now I was always bound to a maximum exposure time of about 20 seconds due to the earth rotation. This time I decided to put the camera - an EOS6D with a Samyang 2.8/14mm lens - on top of an EQ6 mount. This way much longer exposure times with a lower ISO value (i.e. less noise in the image) were possible without getting any star trails. I took 6 frames with ISO 1600 á 148 seconds each. The total exposure time is therefore about 15 minutes.

The frames were then post-processed with rawtherapee and averaged using the ImageMagick "convert" tool. In addition 4 frames of the foreground (the house) were taken and also averaged (of course with disabled EQ6 mount). Finally the two pictures were overlaid and merged with the help of a mask using gimp.

To me it is amazing to see the Andromeda Galaxy (M31), the California Nebula (NGC1499), the Orion Nebula (M42), the Pleiades (M45) and the Horsehead Nebula (B33) clearly on this photo. This overview picture gives a good idea of the brightness, size and exact location of the objects compared to each other.

A full resolution image of the result can be found here. Another image without object descriptions can be found here. I am curious to repeat this procedure in summer when the bright part of the Milky Way will be visible again 🙂

Stargazing time on La Palma - Casa Las Flores

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!

¿Por qué dormir en un hotel de cinco estrellas si puedes dormir bajo millones de estrellas?

This image of the Milky Way has been recorded in a clear, cold night not so far away from Roque de Los Muchachos. It has been recorded with an EOS6D in combination with a Rokinon 14mm/f2.8 fast lens. The exposure time was 20s with ISO6400. A darkframe has been subtracted later on. The RAW file has been developed using rawtherapee. For correction of vignetting and perspective a lens correction profile from this website has been used (btw. thanks for providing this profile!).

The image is also available in full resolution (3.1MB).

First Astro-Tour on La Palma with own equipment

Well... I like the moon... but... YEAH! He is gone! Time for astrophotography, again! 🙂 For this purpose I rent a VW Caddy here on La Palma. The plan: Put all the equipment and my girlfriend into the Caddy and drive up to Mirador del Jable - a quite popular place for watching the stars.

One last look at the weather forecast from aemet... Looks quite promising! Even though it is almost impossible to predict the weather on La Palma. Furthermore, hdmeteo can be helpful to get an idea of the current weather conditions on the island. And last but not least the NOT webcam can give another impression. The decision has been made - tonight will be an astro-night!
