VdB 14 & 15 (left in the picture) are two very beautiful reflection nebulae, which also contain a few reddish emission components and belong to an even larger dust cloud in the inconspicuous constellation Camelopardalis. VdB 15 is the larger, lower area of the nebula and surrounds the star CE Cam, a variable supergiant. VdB 14, the upper part of the nebula, is located near the star CS Cam, which is also a supergiant. The distance to earth is around 3,000 lightyears.

The open star cluster Stock 23 can be found on the right in the picture and is also a nice object for visual observation. Its distance is estimated at 1,240 lightyears and it is surrounded by several spectacular dark clouds. It is embedded in the large but faint emission nebula SH2-202, which extends over the entire right half of the picture.

COBS (Comet OBSveration database) contributions indicates that C/2021 Leonard had a significant outburst just prior to its recovery in the evening sky on December 15/16 2021. The comet flared to mag 3.5 and then quickly subsided to mag 5 by December 18. These three images were captured with a Vixen VSD 100 mm telescope and a Nikon Z7II camera mounted on a Vixen SXP. About 2.5 minutes of images were acquired with subs and stacked with AstroPixelProcessor and finished with Photoshop. With clouds and haze in Tucson and Comet Leonard gaining altitude each day the differences shown are not normalized and are a qualitative product of the captures.

This wonderful dark nebula in Cepheus (Barnard 150 / LDN 1082) is commonly referred to as the "Seahorse Nebula", but in the orientation of my image, the structure reminds me much more of a mermaid, drifting through the cosmos with her long hair.

Its counterpart is played by an H-Alpha cloud, which already belongs to the adjacent "Flying Bat Nebula" (Sh2-129). To bring out this faint area, I captured 7 hours of Ha and then combined it with 10 hours and 24 minutes of RGB. I hope you like it!

This is the wonderful globular cluster M 3 in Canes Venatici. It‘s one of the largest and brightest, and is made up of around 500,000 stars. It is estimated to be 11.4 billion years old and 32,600 light-years away from Earth. I had already photographed this cluster for about 3 hours last year and was able to add another 2.5 hours this time, which made the faint stars in the outer regions of the cluster more visible. Well, M 13 in Hercules is even more spectacular, but I think M 3 is worth to take a closer look at it. Hope you like it!

Comet ATLAS C/2019 Y4, discovered in December 2019, has been quickly increasing in brightness over the last few months, and many of us hope that trend will continue; past projections put it as reaching naked-eye brightness this April or May. However, it's brightness has recently plateaued around magnitude +8. That and an elongated nucleus suggest that it might be disintegrating.

It was likely about magnitude +8 when I photographed it last night, April 9th, near Star 42 Camelopardalis. I'm not sure what the faint nebulosity is to the lower left of the comet: either Dark Nebula HSVMT 25, integrated flux nebula (IFN), or it's simply an artifact. Galaxy NGC 2366 is also apparent in the upper right corner.

Polaris & ses nébuleuses sombres

-

-

-

Aujourd’hui, je vous fais découvrir les nébuleuses sombres qui accompagnent l’étoile polaire.

Cette étoile sert depuis des millénaires comme point de repère entre autre pour la navigation. Elle nous sert aussi à nous aligner pour nos montures équatoriales puisque toutes les constellations tournent autour de Polaris.

Que viennent faire les nébuleuses sombres dans cette histoire ?

Elles sont présentes autour de notre étoile polaire. En anglais, elles sont appelées IFN pour « Integrated Flux Nebula ». Elles sont principalement composée d’hydrogène moléculaire et d’hélium.

Cependant, ce n’est pas aisé de pouvoir les photographier. D’une part, comme leur nom l’indique, elles sont obscures.

Ce sont des nuages denses qui absorbent la lumière des étoiles en arrière plan.

D’autre part, au moment de la prise de vue, elles sont invisibles. Très pratique me direz vous… Même constat au moment de l’empilement, il n’y a que le traitement qui permettent de les mettre en valeur.

A titre d’exemple la tête de cheval (IC434) dans la constellation d’Orion fait partie des nébuleuses sombres les plus connues.

The 'W' of Cassiopeia has always been one of my favorite constellations - maybe because I could always spot it as a kid.

This extent contains the middle three stars of the 'W' - Ruchbah (blue, bottom), Navi (blue, upper left), and Shedar (yellow, upper right). The center star of the 'W', Navi, illuminates the Gamma Cassiopeiae Nebulae (IC 59 and IC 63) a combination of red emission and blue reflection nebulae. The red/pink emission nebula below Shedar is the Pacman Nebula (IC 11 or NGC 281). And to the right of Ruchbah is the Owl or E.T. Cluster (NGC 457); the owl or E.T. is upside down here.

Thin cloud cover was present most of the time that I imaged and acted as a diffusion filter for the larger stars. I kind of like this effect that emphasizes big stars, especially for this extent where the nebulae are fairly small for a focal length of 135mm, although I'd always prefer clear skies to a natural diffusion filter. Even though my tracking was spot-on (good balance, polar alignment, and a charged SkyTracker), I wasn't able to use about half of my subs because of clouds.

Galaxy IC342 can be found in a dusty region, 10 degrees from the Galactic Equator but that dust is not very bright. Almost all IC342 images show just the Galaxy, not the dust in the surrounding region. It was not my intention to image that dust, but when i made a luminance stack with all the 271 (300 second) subs i had, there it was....

The inverted image is annotated and i added surface brightness data for a couple of faint Galaxies. KK35 or PGC166077 with a surface brightness of 26.85 mag/arcsec² was thought to be a Dwarf Galaxy but it most likely is an outher region of IC342.

The Lagoon Nebula is one of the brightest nebulae in the night sky - bright enough for some people to see with the naked eye as a hazy patch in the sky. Around 5,000 light years from earth, this giant interstellar cloud is a nursery for young stars. These baby stars heat up the nebula gas so much that it emits light - light we can see. We may not see much with our naked eye but with a little help and a little patience, we can see a whole lot more.

Calibrated images of the Lagoon Nebula were provided by iTelescope.net. In addition to providing access to their telescopes, iTelescope.net provides subscribing members with a combination of premium image sets (with the rights to use & post them) and webinars that show how to process them. Itelescope.net captured the images using their T71 telescope based in the dark skies of Chile. I handled the post-processing side with Astro Pixel Processor, Photoshop, Star Xterminator, and Topaz Sharpen and DeNoise AI.

A region of active star formation in the constellation Cygnus glowing in the light of hydrogen gas. On the left is NGC 7000, also known as the North America Nebula, and on the right is IC 5070, a.k.a. the Pelican Nebula.

This is a mosaic of seven tiles, taken with two different astro cameras on three nights in July and August. Explore Scientific 0.1m f/7 telescope, ZWO ASI 294MC (one-shot color) and ASI 2600MM (monochrome) cameras, UV/IR cut fillter, iOptron CEM25P mount, ASIAir controller, auto-guided. Processed in Astro Pixel Processor and Lightroom.

On April 15th, 2023 minor planet (270) Anahita passed by galaxy NGC 4939. I captured this encounter with a remote telescope in Auberry, California. Unfortunately this was about 16 hours after the close encounter, but the minor planet is still in the field of view. To my suprise I found an other minor planet, which is the still unnamed (35954) 1999 KY15.

The image is a stack of 20 frames of 180 seconds each. The minor planets are only shown in 7 frames each, to better show the movement.

Equipment: Planewave 24" (0,61m) CDK, F=3962mm, f/6.5, FLI-PL09000 CCD camera, Mount: Planewave Ascension 200HR.

Processing with AstroPixelProcessor and Photoshop.
