Messier 16 - Pillars of Creation and source for young stars
More infos: https://www.skypixels.at/m16_info.html



The image shows the center of Messier 16 (or Eagle Nebula) which actually consists of two objects: an open star cluster, with the catalog designation NGC 6611, and a bright HII region - IC 4703. The nebula is mainly a hydrogen cloud in which a very active star formation process is taking place.
The most popular detail of this nebula is the column of dust in the center of the image - the "Pillars of Creation".

Hereby I submit my latest image. It’s from the famous Comet C/2022 E3, imaged last week when it zipped through the constellation of Auriga. Just past Iota Aurigae and farther away the Flaming Star and Tadpole Nebula.

I used different setups to create this composition. Much needed, since the contrast was too large to image simultaneously. The image was taken from my backyard in Sneek, the Netherlands.

Setup:

Skywatcher HEQ5, Sharpstar 61 EDPH II, ZWO ASI 533MC PRO and an astromodified Canon 6d with and Optolong L-Enhance dual narrowband filter.

“The moon’s an arrant thief, and her pale fire she snatches from the sun.”

Timon of Athens
Act IV, scene ii

If Shakespeare had known about narrowband filters, equatorial mounts, and CMOS camera sensors, he might have written these lines about AE Aurigae, the variable runaway star that is presently passing through and illuminating an interstellar cloud of gas and dust and giving rise to what is known as the Flaming Star nebula.

This framing evokes for me the feeling of falling into this cauldron and whirlpool of ionized gas. 17 nights were necessary to capture these 37 hours of data, as this was captured late in the season and IC 405 wasn’t above my local horizon for more than two hours during the night toward the end.

Processed in the Hubble palette in PixInsight. Data was acquired from my backyard in Santa Monica, CA using the following gear:

Camera: ZWO ASI6200MM-pro
Scope: William Optics Fluorostar 132mm Refractor
Mount: Astro-Physics Mach2GTO
Filters: Chroma 3nm Ha/SII/OIII 50mm

Hello,

I’m Davor Orel and I propose the last of my photograph as a possible APOD. I shot it with my equipment in a single night (4h:27m) from the Maniva mountains near Brescia (Italy), it shows what is possible to achieve with a decent sky and amateur equipment in a single short photo session . The image was then processed by a dear friend (@AstroDOC) who, with the combined magic of PixInsight and Photoshop, was able to extract all the signal present in the 267 at 60" shots and 63 at 10" shots, merged into a HDR showing all the beauty of the Orion nebula. Thanking you for your attention and for the beautiful images that make us dream every day. Keep it up and clear skies.

Hello,

On the evening of February 13, from 10-12 pm CET, the sky was very clear and I took the opportunity to image the comet one last time. It was passing between Mars and Aldebaran, right in the cluster NGC 1647.

I wanted to frame it wide in order to have lots of colors on the image:
- red with the California nebula
- orange with Mars and Aldebaran
- blue with the Pleïades
- green with the comet
- black areas with all the dark nebula in this area

So I took my brand new full frame Canon EOS R6 mark II, with a Sigma 70-200mm f/2.8 Sport, mounted on an Astrotrac TT320, a sturdy (and antic) Manfrotto 144B tripod and traveled to the observatory of the Societe Astronomique du Havre, 15 miles away from the urban light polluted area.

Settings :
60 seconds x 138 (best over 167 images)
70 mm f/2.8, ISO 1600
Alignment and stacking with Siril
Post treatment with Photoshop

Captured the center of the Orion constellation Monday night in this exposure with about 22 minutes of data. I don't have an astro modified camera, but I was able to pull out the little Ha data that the A7iii could capture and enhanced it to bring out those details. It's amazing how large these objects are in the night sky. If only our eyes could see what the camera can see!

Thank you, that's a really great image! I can see so much in it - not just the comet, Mars, the Pleiades and the California Nebula, but also the Hyades, IC 348, Barnard 22 and the Baby Owl Nebula, among other things. You made all the nebulosity in Taurus look so impressive. I really like it!

And forgive me for asking, but are you by any chance a woman? I'm asking because your name, Michele, would be a woman's name in my country. But maybe not where you live.

Thank you, I really like your image! I actually particularly like what you pointed out yourself, namely that you captured the comet just as it was passing in front of cluster NGC 1647. There are also a number of well-known deep sky objects in your image, and you have brought them out well and shown them in very fine color. I like the wealth of small background stars in your image, too.

Welcome to Starship Asterisk*!

Thank you Ann, yes it's a very dense region in the sky and definitely one of my favorite!
(Michele, with one "L", is a male name in Italy)

Bode's galaxy (m81), Cigar galaxy (m82) and many others:

I was always intrigued by this part of sky. In addition to two beautiful large galaxies (m81 and 82), it has many other faint and small (as visible to us) galaxies. At first I wasn't sure if I would be able to capture them with my equipment. I also had very short time left before I had to pack up and head home. It was last month during my visit to Death Valley, CA. I'm pleased with the result after seeing many smaller and faint objects.

Thank you so much Ann. Note that I did a version better showing the Integrated Flux Nebula (IFN), though not as much as Michele :

Kind regards, Romain.

I immersed myself in the fascinating beauty of the Orion Nebula, one of the wonders of our universe. Thanks to my passion for astrophotography, I captured every detail of it. illuminated by the intense colors of the young stars within it. This photo were taked in the province of Brescia, Italy, from February 10th to 17th, using a Canon 1200D camera, a 72/432 telescope and a SkyWatcher AZ-GTi mount, under a Bortle 4 sky, with only a UV-IR cut filter. It took me a total of 8:09 hours of integration time, which involved taking 163 shots of 180 seconds each, as well as 70 shots of 10 seconds each for the core. Capturing images like these makes me feel part of an ever-evolving universe, where every shot represents a piece of the puzzle that helps us better understand our place in the cosmos.
