To enhance our amateurs’ abilities of astro-observation and astrophotography, to stimulate the public’s imagination and creativity, and to better feel the beauty of the stars, universe and science. We have the ASIWEEK ASTROPHOTOGRAPHY now. We sincerely invite global astronomers and photographers to participate.

Here are the fantastic works from the 28th edition of 2019 ASIWEEK ASTROPHOTOGRAPHY COMPETITION. Let’s take a look!

It is Marcel Drechsler and his target LBN 569 captured with ZWO ASI1600MM Cool that won the championship.

Little Ghost Nebula is a planetary nebula in the constellation Ophiuchus. It was discovered by William Herschel.

Round and planet-shaped, the nebula is also relatively faint. Planetary nebulae are not related to planets at all, but instead are created at the end of a sun-like star’s life as its outer layers expand into space while the star’s core shrinks to become a white dwarf. The transformed white dwarf star, seen near the center, radiates strongly at ultraviolet wavelengths and powers the expanding nebula’s glow. The nebula’s main ring structure is about a light-year across and the glow from ionized oxygen, hydrogen, and nitrogen atoms are colored blue, green, and red respectively.

The Lagoon Nebula is estimated to be between 4,000-6,000 light-years 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.

Target: NGC 6960

6期-4

Equipment: ZWO ASI071, Optolong L-eNhance, Nikon Lens 300 mm

Ten thousand years ago, before the dawn of recorded human history, a new light would have suddenly have appeared in the night sky and faded after a few weeks. Today we know this light was from a supernova, or exploding star, and record the expanding debris cloud as the Veil Nebula, a supernova remnant. This sharp telescopic view is centered on a western segment of the Veil Nebula cataloged as NGC 6960 but less formally known as the Witch’s Broom Nebula.

 

Photographer: Martin Junius

Target: M65 / M66 Galaxies

6期-5

Equipment: CdC, APT, PHD2, ZWO ASI294MC Pro, Astronomik L2 filter, 29x300s, -10C, gain 120, 30 flats, 30 darkflats, 71 darks, no bias

M65 is an intermediate spiral galaxy about 35 million light-years away in the constellation Leo. It was discovered by Charles Messier in 1780.

M66, is an intermediate spiral galaxy in the equatorial constellation of Leo. Also discovered by Charles Messier.
