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.

Mgławica Laguna - M8 (NGC 6533) z powiększeniami

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.

Mgławica Laguna - M8 (NGC 6533)

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.

Vega

is the brightest star in the northern constellation of Lyra. Vega has been extensively studied by astronomers, leading it to be termed “arguably the next most important star in the sky after the Sun”. Vega was the northern pole star around 12,000 BC and will be so again around the year 13,727, when the declination will be +86°14′. Vega was the first star other than the Sun to be photographed and the first to have its spectrum recorded. It was one of the first stars whose distance was estimated through parallax measurements. Vega has functioned as the baseline for calibrating the photometric brightness scale and was one of the stars used to define the zero point for the UBV photometric system.

M92 (NGC 6341)

is a globular cluster of stars in the northern constellation of Hercules. M92 is at a distance of about 26,700 light-years away from Earth.

M92 is one of the brighter globular clusters in the northern hemisphere, but it is often overlooked by amateur astronomers because of its proximity to the even more spectacular Messier 13. It is visible to the naked eye under very good conditions. Among the Milky Way population of globular clusters, Messier 92 is among the brighter clusters in terms of absolute magnitude. It is also one of the oldest clusters.
