I have been working on this very wide image of the Orion region on and off for the last 18 months. Its a mosaic taken with 70mm and 35mm camera lenses as well as 5 inch and 4 inch refractors. To give you an idea of how this image was assembled it's a 9 image mosaic for the overall star background taken with a 35mm camera lens. Then embedded within it are other mosaics. There is a 4 image mosaic of Orion taken with a 70mm camera lens. Then within that mosaic is another 4 image mosaic of the Horsehead and M42 taken with a 4 inch refractor. The area around the Rosette and Cone is a 10 image mosaic taken with a 5 inch refractor. There are also other images and mosaics in there taken with the 4 and 5 inch refractors (e.g. California, Seven Sisters, Flaming Star, Tadpole, Jellyfish, Monkeyhead, Witch Head, Moldy Strawberry). So in all this is hundreds of hours of data collection all assembled together. You can find a higher resolution image here:

Venus and the Pleiades over Althofen (Carinthia, Austria).
Single shot. No tracking, no stacking, no blending.
Located in the Grus Constellation, are all 4 spiral galaxies.
Further up we have NGC 7552, the smallest of the three below is ngc 7590, with its mate next to ngc 7599. The most central and most studied of them is NGC 7582.
NGC 7582 is a type 2 Seyfert galaxy, such a classification is due to the fact that the galaxy has an extremely bright supermassive central black hole very similar to a quasar (most energetic objects in the universe). The black hole of NGC7582 is about 10 million times the mass of our sun.

Piedras Rojas
Piedras Rojas is one of the most visited places by tourists visiting the Atacama Desert in Chile.
Despite the beautiful scenery that can be enjoyed during the day, it is during the night that the show takes place. Above 4300 meters above sea level and far from any source of light pollution, watching the night sky from there is an unforgettable experience.
In this self-portrait made in April/16, we can identify the planets Mars and Saturn, just above the Milky Way core. In addition, we can see a beautiful Air Glow ranging from green to red tones giving a special color to the sky of Piedras Rojas.

These two sets of interacting galaxies are listed in Halton Arp’s Atlas of Peculiar Galaxies as Arp 296 and Arp 299.
Arp 299 is the larger set at the center of the image and consists of NGC 3690 and IC 694. There are numerous peer-reviewed publications on Arp 299 that discuss regions of powerful starburst activity, as well as eight supernovae detected during 1990 – 2010. An article published in August 2018 reports a possible tidal disruption event (TDE) “produced when a star is ripped apart by the gravitational field of a supermassive black hole (SMBH)” [https://science.sciencemag.org/content/ ... 1/482.full]. Arp 299 is approximately 130 million light-years away.
Arp 296 is at the right of center in the image and consists of a quite distinct barred face-on spiral galaxy (PGC 35345) and a less distinct galaxy (PGC 2580146) exhibiting filamentary structure on either side. Arp 296 is much further away than Arp 299 at an approximate distance of 800 million light-years.
I found very few on-line images of this field. The most prominent are a broadband image of Arp 299 from the Hubble telescope as well as hybrid images combining Hubble data with x-ray data from NuSTAR and Chandra. I have found no images that show the broad tail stretching from Arp 299 to the blue star at lower right in my image. The Hubble-based images and others published in professional literature tend to be tightly centered on Arp 299 and do not show the wider field. There are many other galaxies visible within this field.

Amazing night in Mangue Seco, Brazil (March 2018).
The Mangue Seco dunes gained fame in Brazil in the 90s due to the exhibition of a soap opera of great audience recorded in the place. In addition to the beauty of the dunes, Mangue Seco also offers excellent conditions for capturing the night sky, especially when the Milky Way core appears on the horizon over the sea. In this image, the light emitted by an operating oil platform painted the horizon in the left corner of orange.

The moon illuminates the Baltinache Lagoons during an incredible night in the Atacama Desert in Chile.
Although the moon's luminosity somewhat disturbs the capture of the night sky, it is possible to identify the magellanic clouds on the right in the image.
