This wonderful vista in Scorpius, captures the beautiful open star cluster M6, also known as The Butterfly Cluster, fluttering across the back drop of the distant golden star clouds of our Milky Way galaxy, leaving a turbulent dust trail behind her.

GABRIELA MISTRAL NEBULA - The nebula shaped like a human face in profile

This nebula is a nursery of stars that presents the shape of a 'human face' in profile.
The nebula's technical name is NGC 3324, but she is also known as Gabriela Mistral, the name of the Chilean poet chosen as the Nobel Prize for Literature in 1945, due to the profile face, formed by the gases and dust in the place.

Solstice Comparison
Copyright: György Soponyai

The first picture was taken atop Storsteinen mountain near Tromsø, Norway in June, 2019. The city lies 350 kilometres North of the Northern Polar Circle so the Sun does not set there between 20th May and 22nd July. Standing at a mountaintop 24 hours for observing and capturing the Midnight Sun was not easy and comfortable but I guess it was worth it.. The foreground photo was taken at local midnight (00:45).

I took the second picture last Wednesday near Mogyoród, Hungary three days after Summer solstice. This 16-hour-long photo session was neither an easy run due to the ~30 °C temperature, the lack of shadows and the trailing clouds that prevented me keeping the constant 20-minute-pace of photographing the Solar "dots". I took the foreground photo at local noon (12:44).

Besides presenting the "Longest Days from Different Regions of Earth" as pure astronomical phenomena, placing these photos next to each other we can compare the difference of illumination and colors depending on the height of the Sun (shines from the horizon or atop our head). And it also matters whether we are standing on the top of a snow-patchy mountaintop or in the middle of a bushy meadow.

The Iris Nebula NGC 7023

The Iris Nebula (also known as NGC 7023 and Caldwell 4) is a bright reflection nebula in the constellation Cepheus. The designation NGC 7023 refers to the open cluster within the larger reflection nebula designated LBN 487.

The nebula, which shines at magnitude +6.8, is illuminated by a magnitude +7.4 star designated SAO 19158. It is located near the Mira-type variable star T Cephei, and near the bright magnitude +3.23 variable star Beta Cephei (Alphirk). It lies 1,300 light-years away and is six light-years across.

Couple of questions arise:
Which star cluster is on the mask? I believe is the one of Gabriela's preference!
Is the cluster in the same orientation as the nebula?
Thanks for looking,

The cluster on Gabriela's face mask is NGC 3293. It's quite nearby from Gabriela's point of view, but it's not right up on her face!

Gabriela does not seem to be looking straight at NGC 3293. Look at this photo by Gramho Astrobin: https://scontent-lga3-1.cdninstagram.co ... e=5F0C48D1

Comet C/2020 F3 Neowise at 03:09:37 CEST

Story: This comet is relatively new. However, its clarity and observational conditions open up space for a wonderful spectacle not only in the evening, but also at dawn, as it was today.

Yesterday's trip to this comet did not come out due to bad weather and the low altitude from which I took pictures, so I had to plan better and I went to the mountain Ondřejník, from which I could take photos from an altitude of 690 m above sea level. Succeeded! For this comet (and the clear NLC that are appearing now), I haven't slept well in 3 days. Even so, I'm very happy to be able to take a picture of her. She is gorgeous.

Thanks for your reply Ann!
And yes, it is true that the Gem cluster is not straight ahead of Gabriela, but it is on top, in forehead direction, so from my perspective it is indeed in her thoughts! Sorry about my crazy imagination!

North American Nebula & Pelican Nebula in SHO
RedCat 51 + ASI1600MM Pro


"The American Pelican"

On the left, bright emission outlined by dark, obscuring dust lanes seems to trace a continental shape, lending the popular name North America Nebula to the emission region cataloged as NGC 7000. To the right, just off the North America Nebula's east coast, is IC 5070, whose profile suggests the Pelican Nebula. The two bright nebulae are about 1,500 light-years away, part of the same large and complex star forming region. At that distance, the 6 degree wide field of view would span 150 light-years.

This cosmic portrait uses narrow band images to highlight the bright ionization fronts in false color, also known as Hubble Palette, same technique used by the famous Hubble Space Telescope. After more than 11 hours of exposures using a monochrome camera with Hydrogen Alfa (red), Sulphur (green) and Oxygen (blue) filters ended up with three black and white pictures, one for each filter, representing the gas in the nebula. The first picking up light in the frequency of Sulphur ions (assigned to the color red), the second Hydrogen (green), the third Oxygen ions (blue). Switching the red channel (Hydrogen) with green (Sulphur) reveal details that the human eye cannot easily see, if at all.
