🌐Blue snowball nebula ngc7662 in constellation Andromeda. Small and bright (short 30s exposures). I had to find the sweet spot to make the inner structure visible. Happy to see it’s unique features appearing. #ngc7662 #bluesnowballnebula Size 0.5x0.5arcmin #planetarynebula #astrofotografie #astrophotography #narrowbandimaging #ioptroncem25p #williamopticszs73 #asi533mcpro #asiairpro #optolonglultimate #astropixelprocessor #starnetv2 320x30s bortle5 sky

Ngc7027 planetary nebula (PN) in constellation Cygnus. Combination of 3hours of 600s long and 3hours of 30s short exposures. Quite challenging to remove the overexposed PN (see photo grid). The PN has a spiky rectangular shape. The hydrogen clouds creates a nice background. #ngc7027 #planetarynebula #narrowbandimaging #astrophotography #astrofotografie #ioptroncem25p

Bortle5 sky

Sh1-89 planetary nebula, IC1369 open cluster, dark nebula in constellation Cygnus. There are a lot of tiny planetary nebulae with a variety of interesting forms, but often hard to image. This one is a nice combination of clustered stars, dark nebulae, hydrogen nebulae and this planetary nebula #sh189 #planetarynebula #ic1396 #astrophotography #ioptroncem25p #asiairpro #williamopticsz73 #optolonglultimate 3nm dualband 9h45m 900s subs #narrowbandimaging #astropixelprocessor bortle5 sky

The Veil Nebula Complex
===================

The Veil Nebula is a large supernova remnant in the constellation Cygnus. The source supernova exploded between 10.000 and 20.000 years ago, and the remnants have since expanded to cover an area roughly 3 degrees in diameter (about 6 times the diameter, and 36 times the area, of the full Moon). The distance to the nebula is not precisely known, with estimates ranging from 1,400 to 2,600 light-years.

Sadr Region and Crescent Nebula
=========================

With an apparent magnitude of 2.2, Sadr is one of the brightest stars in the night sky, forming the intersection of an asterism of five stars, called the northern cross. The huge star in the center of the image is located about 1.800 lightyears from earth.

The Crescent Nebula (NGC 6888) in the top right is a cosmic bubble of gas and dust, created by the stellar wind of the Wolf-Rayet star WR 136. The nebula is located at a distance of about 5.000 lightyears from earth.

The Iris Nebula
===========

The Iris Nebula, located at a distance of about 1.300 light-years from earth in the constellation Cepheus, is a reflection nebula, which means that it shines by reflecting the light of the star SAO 19158, which is located in the center of the nebula. It’s also known as the “Flower Nebula” due to its shape and colors. The nebula is surrounded by dark clouds of interstellar dust, which give it its distinctive shape.
