NGC 1672 by William Ostling, on Flickr
Full write up here: https://theastroenthusiast.com/ngc-1672-from-hubble/
NGC 1672 is a barred spiral galaxy in the constellation Dorado. Its massive spiral arms display clusters of hot young blue stars , and beautiful clouds of pink ionized hydrogen gas. Dust lanes throughout the galaxy obscure and redden the light of the stars behind them. NGC 1672’s dynamic core is emphzised by the ring of hydrogen gas and dark dust lanes around it.

The parade of the planets, an almost perfect alignment between Venus, Saturn and Jupiter. In the photo it is possible to appreciate the planet Venus (the brightest one) reflected in the sea and diagonally to follow Saturn and then Jupiter.
The photo was taken by Giuseppe Conzo (Gruppo Astrofili Palidoro) in Marina di San Nicola on the Roman coast as a sum of 6 photos of 16 seconds ISO-1200, a magical setting for this astronomical phenomenon.

Here an image of the Geminides meteor shower as seen from the cockpit at an altitude of 40.000’. It was taken yesterday morning on a flight from Denmark back to The Netherlands. Being high above the clouds meant we wouldn't be bothered by the thick clouds which covered most of Europe during the peak of this year’s shower. The landing light I switched on for a better composition, to lead the eye towards the constellation of Gemini.

The image is a composite of 10 different images, blenden together in Photoshop. Taken with a canon 6D an a Samyang 14mm lens.

California in space

Located in the Perseus constellation, The California Nebula appears to outline the state of California. Also known as NGC 1499, this emission nebula is around 100 light-years long. The star most likely providing the energetic starlight that ionizes much of the nebular gas is the bright, hot, bluish Xi Persei (Menkib) just to the left of the nebula in this image.

Location: Georgetown, Texas
Total exposure: 15 hours 15 minutes

The Sirius Color Wheel

Hi, I’m Davor Orel, from Brescia (Italy) and I would like to show you the photograph I made based on the color circle invented by Johannes Itten, which I learned when I went to school as a child to learn primary colors.
To make it, I used about 4000 shots of Sirio, from the balcony of my house in Brescia (Bortle 7) on the night of December 13, 2021, blurring it to enhance its colors. Each single dot is a photo of Sirius, taken with his original colors.
For the shots I used an Askar FMA180 with QHY163C and L-Pro filter, mounted on AZ-GTi, all connected to a Win 2 GPD converted for astrophotography. Filming was done with SharpCap, set to generate single frames in TIFF, the first processing (crop and debayer) was done in PIPP, converted to JPG with a batch of Photoshop, and then AndreaMosaic for the creation of the mosaic picture.

Thanks for your attention, sure you will like it, I wish you happy holidays and a happy new year!

This is the original Itten color wheel.

here is my attempt to make the crab nebula look as much like the famous hubble image of 2000.
i spent quite a while tweaking on the colors

the real gem is the video where i aligned the images and switched back and forth so you could see the expansion over the past 21 years. you can see that on my facebook https://www.facebook.com/groups/8615172 ... 450244961/

i hope the link works

i used an Edge11 SCT
QSI6120 astrodon 3nm Ha and OIII filters

ImageThe triple conjunction by Manuel Natale, on Flickr

The triple conjunction

On the morning of August 18 Venus and Jupiter are separated by just one quarter of a degree: their closest conjunction since 2000! This is, without doubt, the most spectacular conjunction of the year.
The following morning, the two planets begans to separate once more, but only 6 day later, in the early morning of August 24, will be possible to admire them to the presence of a third wheel: the Moon, not an any one, but the thinnest crescent Moon before the New Moon of the day after.
So, one hour before the sunrise looking at the horizon in the east-northeast direction, here is its thin lunar crescent joins the two planets providing a magnificent scene in a shape of an isosceles triangle, set against the colours of dawn with the black profile of a refuge , some trees and clouds at the top of the mountain in front of the sea.


Place and date of the shot:
1638 m MSL Fonte Tettone, Abruzzo, Italy - 05:33 24th August 2014.


The triple conjunction of Venus-Jupiter-Moon of the 24th August 2014 is litterally the first image of my career in this magnificent world shooted with a simple Nikon D5100 (using a 55mm at f5.6, 1/10 sec. ISO 100) and barely retouched with PS only in terms of lights.

Interstellar Cloud, Bok Globules and Pareidolia in the Rosette Nebula


What do interstellar dust clouds have in common with pareidolia?
The human brain is extraordinary. During his evolution he got used to recognizing familiar structures and forms everywhere, even in abstract scenarios.
Thus observing the molecular clouds present in the Rosette nebula, an emission nebula more than 5200 light years away from our planet, it might seem to us to distinguish forms of animals, faces, objects of common use.
This illusion is the same one we use to characterize the shapes of the clouds or when we have the impression of recognizing a typically human expression on the face of our pets.

To illuminate this wonderful emission nebula (NGC 2244) we also find an open cluster of young stars located in the center (NGC 2237) and, among the columns of dust, we can distinguish several Bok globules. A tribute in the name to Bart Bok, the astronomer who first hypothesized that these small compact dark nebulae could be precursors of the protostars, themselves a version that predates the formation of a new star.

The editing in Hubble Palette SHO (SII: H-Alpha:OIII) is always a very three-dimensional and suggestive representation to appreciate all the small details of the emission nebulae. Although the colors are not realistic, the dynamic rendering always has a very strong impact.
