Messier 6: The Space Butterfly

Nicknamed the butterfly cluster for its resemblance to a butterfly, it is located in the constellation of the scorpion, approximately 1,600 light-years away.
Messier 6 is best seen in binoculars, it is about the size of a full moon. The cluster contains over 300 stars, with binoculars it reveals only a few dozen and a small telescope will show little more.
Its first reports are a mystery, it is believed that its first record was by the Greek astronomer Claudius Ptolemy while observing neighboring Messier 7 (Ptolemy's cluster) in the 2nd century CE, which is just five degrees southeast of M6. In describing the nearby cluster M7, Ptolemy noted 'Girus ille nebulosis' meaning '2 small clouds'.

In the image submitted above, which is a time lapse composite spanning 0.42s, one can easily see both Mizar A and B, as well as Alcor, and their relative brightness values compared to the ISS, which passed by at an apparent rate of 2960 arcseconds/s. The telescope used was a C9.25 Edge HD, and the camera was an ASI183mm. Shutter speed was 0.8ms and the frame rate was 38.5 fps, using 2x2 binning. The image has global gamma and white/black level adjustments to the exposure (relative brightness is preserved). Image taken on July 13, 2021, at 21:38:28 PDT from San Diego, CA.

The mysterious globular cluster NGC 3201

Ngc 3201 is a cluster of stars, located in the constellation of Candle, discovered in 1826 by Scotsman James Dunlop, who won Gold Medal from the Royal Astronomical Society in 1828.

This cluster has an interesting peculiarity, astronomers have discovered a star in the globular cluster NGC 3201 that is behaving very strangely, it appears to be orbiting an inactive black hole with a minimum mass of 4.36 solar masses, suggesting it is the first cluster to show a black hole. This article was published in an article in the Royal Astronomical Society's Monthly Notices, January 17, 2018.

NGC 3201 has an extremely fast speed relative to the Sun and its orbit is retrograde, meaning that it moves quickly in the opposite direction to the galactic center, this suggests that it originates from outside the Milky Way, despite its chemical composition be similar.

IC 5068

This is IC 5068, located in the neighbourhood of the North America and Pelican nebulae. Specifically, IC 5068 is situated very close to the massive and bright star, known as Deneb. The nebula is mostly known for the streaks of dark clouds that separate the colourful hydrogen regions, which also cordon the nebula off from its better-known neighbours. (All are located 1,600 light-years away in the constellation of Cygnus.)

We may have felt like we were living in a bubble the last 16 months but if there is life here, they really are! This is NGC 7635, the Bubble Nebula taken with a Planewave CDK14 at Sierra Remote Observatories. This is 28.5 hours presented in an SOH palette.

High Beta Angle
Copyright: György Soponyai

Maybe this photo is rather interesting than spectacular.
The International Space Station orbits the Earth with an average altitude of 420 km and inclination of 51.6°. Due to this high inclination, four times every year during a less-than-a-week-long period the ISS is being illuminated by the Sun continuously so it's visible and observable the whole night from the Earth. These periods are called High Beta Angle Seasons. Two of these periods (in May and July) are visible on the middle and high latitudes of Northern Hemisphere, the rest two periods (in November and January) are visible on the Southern Hemisphere.
The second Northern HBA period of the year occurred this week and I was able to observe and capture eight transits of the Space Station during two moonless and cloudless nights near Mogyoród, Hungary. Recently the sky above Europe is full of Saharan dust as it's clearly visible over the horizon.

I am pleased to introduce you to the Tulip Nebula. Sh2-101. In the cygnus constellation.
Image made in Hubble palette. Accumulating 45 hours of exposure, in 60 sub-shots of 15 minutes for each filter (Ha, OIII, SII).

The photograph is taken from the skies of Ager, through my remote observatory.
The equipment used consists of a Takahashi FSQ106 telescope, an ATIK460EX MONO CCD, a Paramount ME mount, and 31mm astrodon filters.
The capture program has been SGPro, and the processed Pixinsight and Photoshop.

The image shows the cygnus X1 shock arc. A powerful black hole that we can observe thanks to the force it makes and causing that arc. Is awesome.

Without further ado, I hope you like the image made.
Thanks!!!
