NGC 2327
(A mix of NB & RGB data).

NB & RGB Mix

When the Milky Way is rising, Lagoon Nebula and Trifid Nebula are easily visible deep sky objects even for naked eyes.
This 20mins exposure night sky also allows us digging into some dark nebulae and dust around galactic plane and thinking
how the dust could be such concentrated to block most of star light. At middle left, it's M22, a bright globular cluster
in Constellation Sagittarius accompanied with some smaller globular clusters around.
Beneath the sky, the snowcap is Mt. Xiaowutai, the major peak of The Taihang Mountains which is running down the
edge of Northern China Plateau.

"On the way to the stars"
Copyright: Martin Činčura


This panorama of rising Milky way core was taken in the middle of Slovakia near one of national parks.
It is a place with relatively good quality of night sky.

I am trying to find my own way to the stars. Typically it is so dark during that nights, so I need some extra light on my journey.
Is this way the correct one?

Picture was taken on 14th of April 2018.

Hi All,

Located in the far southern constellation of Musca, this unusual streak of dark obscuring dust slices across an almost uniform blanket of millions of stars covering 16 square degrees of sky.

First of all


1° 360 panorama
1°milkyway of 2018
1° time there, rly good sky

Story:

When I arrived on the cliff of Sardinia the weather was not good ... A lot of humidity, lots of particles in suspension ... I mounted my setup and I started to track the sky

incredibly, the first shot was excellent, the core of the Milky Way was well legible, the dark nebulosity was well contrasted ...

so despite the clouds I went ahead with my 360 degrees panorama and I managed to bring home a good job.
