The Lagoon Nebula – M8 (NGC 6533)

Is a giant interstellar cloud in the constellation Sagittarius. It is classified as an emission nebula and as an H II region. The Lagoon Nebula is estimated to be between 4,000-6,000 light-years away from the Earth. In the sky of Earth, it spans 90′ by 40′, which translates to an actual dimension of 110 by 50 light years. Like many nebulas, it appears pink in time-exposure color photos but is gray to the eye peering through binoculars or a telescope, human vision having poor color sensitivity at low light levels.

Photos (June 2019) taken at Tenerife, exactly in the place next to “God’s finger”. A great place for astrophotography during night and long conversations about the nature of time, speed of light, wondering if life exists in other planetary systems together with great company, especially with Karol, Magda and Maciek. With those people I want to return there indefinitely.

Equipment: Canon EOS 6D (no mod!) with a Canon EF 200 [mm] 2.8L II USM lens, on a glued iOptron CEM 25 mount, which I accidentally crashed on beton. The next day at the hotel, I disassembled it, made possible repairs, and glued it with a drop glue bought in a nearby store. After switching on, it start to works but it had a leeway thwart of about 1 – 3 [mm] on the head, which meant that I could not take light frames exposure for more than about 90 [s]. I was lucky enough to use it at all and all this with the outstanding help of my friend Maciek, a very kind and willing person to help without whom, it is possible that would come back with nothing from Tenerife. Thank you Maciej.
