Image Gallery

This is a collection of outstanding astronomical images entirely processed with PixInsight. This includes all stages of image processing in astrophotography: analysis, calibration, registration, integration (stacking) and post-processing with the most advanced and accurate tools and techniques available in PixInsight.

This is much more than a collection of images, however. Each image is accompanied with text and figures describing the astronomical objects and their nature, their physical properties and mutual interactions. These contents have been authored by professional astronomers, whose contributions provide us with a wealth of science outreach material.


PK164+31.1 — The Best-Ever Image of a Poorly Known Nebula

This image is, probably, the best one ever obtained of PK164+31.1, a poorly known planetary nebula 1600 light-years away in the Lynx constellation.

Our Neighbor Andromeda

The Andromeda galaxy illustrates the typical phenomena that occur in a normal spiral galaxy, perhaps presenting a similar scenario as if we were to look at our own Galaxy from far away...

Face-On Spiral Galaxy Messier 74

We present a very deep optical image of galaxy Messier 74, in Pisces. This impressive photograph reflects all the characteristic traits of great design spiral galaxies.

The NGC 6914 Nebula Complex

In the deep space there are not only stars, but galaxies like ours contain nebulae: diffuse matter made up of gas and dust. These nebulae display a variety of shapes and colors that reflect the diversity of processes that take place when nearby star light gets tangled among them.

A New Look into the Whirlpool

Every relevant collection of astronomical photographs has to include this object at least once, if not more times, and every new look to this magnificent object reveals different aspects of this grand-design spiral galaxy.

The Ring Nebula

The diversity of colors, shapes, and sizes of planetary nebulae make them fascinating objects. In this photo release Calar Alto presents a rather unique view combining both optical and near-infrared data of Messier 57, the Ring Nebula.

The Owl Nebula

Stars similar to the Sun end their lives as white dwarfs. But, before becoming those dense stellar corpses, they expel their outer gaseous layers and ornate the sky for some thousands of years with the most beautiful objects in the universe: planetary nebulae.

NGC 7331: A Large Spiral Galaxy

The spiral galaxy NGC 7331, in Pegasus, can be seen with small telescopes under dark skies as a faint fuzzy spot. It is an island universe similar to our own Galaxy, or maybe somewhat larger, and placed at a distance of 50 million light-years.
