I like the colors here. The background is blue, which is absolutely correct, since the moonlit night sky is (dark) blue. The Moon itself is overexposed. And Aldebaran, interestingly, is clearly redder than the Moon. I wouldn't be surprised if the overall hue of the Moon is as red as Aldebaran, but the Moon is so bright that it is hard to see its true color. But for Aldebaran, the color is obvious. By the way, I like the fact that the Moon is overexposed, because we all know how bright the Moon is in the night sky and how hard it is to see stars very close to it. I'm glad and impressed that the reddish color of Aldebaran can clearly be seen next to the brilliantly bright Moon!

This is a nice and interesting image!

Thank you so much for your detailed observation regarding color..!! I am so glad.

I much prefer working on Narrow Band images - simply because of the light pollution in my location. But it is now the time for Galaxies and the pretty star clusters.

Messier 3 - just a total of 2 hrs 12 mins RGB - without using the Lum subs that I also had taken.

Using an infrared filter, the Cassini spacecraft peered through Titan's atmosphere to image the surface.

Hello!

This is a GIF of Crab Nebula (M1). If we compare for example the marked area with an image of the same field taken by DSS (Digitized Sky Survey) 63 years ago we can see how some stars look that they have been displaced, also it can be seen as the nebula has expanded!

GIANT SUNSPOT AR2529
One of the largest sunspots in recent times. The sun is like an onion, has layers. The image is a composition where the solar photosphere is shown in Visible light and high solar atmosphere in Hydrogen Alpha with swirling plasma. The Earth shown to scale.

Night Sky Dream!!

Night landscape above the sandy beach of Chalikounas, near lagoon Korission, Natura 2.000, Corfu. With the Milkyway Galaxy lighting-up all the nightsky,
Our Cosmic Island Via lactea, our Galaxy Milkyway floting above the Ionian sea, a cosmic island measure some 100,000–120,000 light-years in diameter and with almost 100–400 billion stars. Our Solar System is about 27,000 light years away from the Galactic Center, while we are on the inner edge of the spiral in the Orion Arm. The rotational period at the position of the Sun is about 240 million years.
The capture is from Chalikounas beach, near lagoon Korission a natura 2.000 area, Corfu, Greece, Earth. While in any other picture you’ve seen the Milky-Way from ABOVE is either another galaxy or an artist’s interpretation.
The Milky Way has several satellite galaxies and is part of the Local Group of galaxies, which is a component of the Virgo Supercluster, which is itself a component of the Laniakea Supercluster.
