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!

It is a combination of 9 luminance frames a 600 seconds exposure time (binning 1×1) and 9 frames a 150 seconds exposure time (binning 2×2) for red, green and blue frames.
A full resolution image is available here.
The three objects shown on the picture are M65, M66 and NGC3628 (also known as the Hamburger Galaxy). All are located in constellation Leo. M65 and M66 were discovered by Charles Messier in 1780. Both are intermediate spiral galaxies and between 35 million and 36 million light-years away. The Hamburger Galaxy is an unbarred spiral galaxy also about 35 million light-years away which was discovered 4 years later by William Herschel.

The seeing conditions tonight were perfect (seeing ~1.95″) and there was no local wind. The annotated image shows a lot of other interesting objects like NGC4323, IC783, NGC4312 and NGC4328 beside M100. Some objects I was not able to assign, yet – those are marked with question marks and could be additional galaxies.
