The Heart Nebula IC1805 – it is kind of obvious why it got its name. The Heart Nebula is an emission nebula and star forming region of almost 200 light-years across, located within the Perseus Arm of our Milky Way galaxy, about 7500 light-years away in the northern constellation Cassiopeia. This is a two-color narrowband […]
A quite busy scenery… including the Bubble Nebula NGC7635 together with the open cluster M52 in the upper right, the Lobster Claw Nebula Sh2-157 in the lower left, and NGC7538 in the lower right. This is a two-panel mosaic of Ha, OIII and SII narrowband exposures with a total of 48 hours (!) worth of […]
Here is the western part of the Veil Nebula, also known as Witches Broom, again as a bi-color image composed of Ha and OIII data taken from my backyard. The Veil is one of the largest and most spectacular supernova remnants. The supernova that created it has exploded 8000 years ago and the remnant has […]
It has been a while since the last few hours of clear skies from my backyard, but now I had another chance. I decided to go for a bi-color image of the Eastern Veil Nebula using Ha and OIII data. The Veil is one of the largest and most spectacular supernova remnants. The supernova that […]
Can you see the pelican? This is Pelican Nebula IC5070 in a tri-color narrowband composite. As with all narrowband composites, these are false colors and the color scheme is largely a matter of taste. Here I use a somewhat conservative and not overly colorful scheme. I am still not completely happy with the post-processing. This […]
