11 hours of integration of the open star cluster NGC 6604 north of the Eagle Nebula form a set of contrasting colors in the middle of the Milky Way.

Hello and thank you for allowing me to post. Towards the end of August and early September, I captured this narrowband image of Melotte 15 from my backyard using a Celestron Edge HD11.
I have about 22 hours of integration time, stacked and processed in Pixinsight as SHO with additional adjustments to drop the overall green cast from the Ha data assigned to the green channel.

Full resolution image can be found here

Thank you!

Messier 22

Copyright: Mark Hanson
Messier 22 or M22, also known as NGC 6656, is an elliptical globular cluster of stars in the constellation Sagittarius, near the Galactic bulge region. It is one of the brightest globulars visible in the night sky.

Taken with PlaneWave 24” CDK at SWOS in Chile.

Unfortunately the colors and resolution here in this small image did not turn out the best but the full version is a must look, its quite impressive and can be seen here:

Thank you,

Mark Hanson

The Antennae Galaxies from Hubble by William Ostling, on Flickr

A full write-up is visible here: ... om-hubble/

The galaxies in this image — also known as NGC 4038 and NGC 4039 — are locked in a deadly embrace. Once normal, sedate spiral galaxies like the Milky Way, the pair have spent the past few hundred million years sparring with one another. This clash is so violent that stars have been ripped from their host galaxies to form a streaming arc between the two. In wide-field images of the pair the reason for their name becomes clear — far-flung stars and streamers of gas stretch out into space, creating long tidal tails reminiscent of antennae.

This new image of the Antennae Galaxies shows obvious signs of chaos. Clouds of gas are seen in bright pink and red, surrounding the bright flashes of blue star-forming regions — some of which are partially obscured by dark patches of dust. The rate of star formation is so high that the Antennae Galaxies are said to be in a state of starburst, a period in which all of the gas within the galaxies is being used to form stars. This cannot last forever and neither can the separate galaxies; eventually the nuclei will coalesce, and the galaxies will begin their retirement together as one large elliptical galaxy.

ImageNorth America & Pelican in HaGO by Joe Schlaf, on Flickr

Image of Pelican & North America Nebulae including the Cygnus wall. This image was taken with 2 narrowband filters (Ha & OIII) and one broadband filter (Green). The HaGO palette is created by combining the three channels to an RGB image with Ha representing Red and OIII representing B. HaGO is intended to represent a more accurate representation of the natural color of the nebula than the SHO (Hubble palette) while benefiting from the pros of narrowband imaging.

Image data collected in Michigan over the months of May, June, and July. This image represents ~17.5 hours of integration time.

Bubble Nebula 70pct-CROP An2.jpg
The Bubble Nebula is an emission nebula. The "bubble" is created by the stellar wind from a massive hot young central star, The nebula is near a giant molecular cloud which contains the expansion of the bubble nebula while itself being excited by the hot central star, causing it to glow.

Presented here in a modified SHO palette.

Also the first fully unguided image with the AP1100GTO CP4 mount using a PE curve and no-encoders.

Average sub Eccentricity was 0.45 which I was very happy with, the stacked image was 0.39.

here an image of IC1396A (The Elephant's Trunk Nebula) I've taken it between september the 1st and september the sixth in brittany, France.
It's my first SHO picture with 3nm narrowband filters. I've used a TOA130NFB on 10micron 1000HPS mount. The astrocamera was a ZWO2600MM.
The Elephant's Trunk Nebula is a concentration of interstellar gas and dust within the much larger ionized gas region IC 1396 located in the constellation Cepheus about 2,400 light years away from Earth. The piece of the nebula shown here is the dark, dense globule IC 1396A; it is commonly called the Elephant's Trunk nebula because of its appearance at visible light wavelengths, where there is a dark patch with a bright, sinuous rim.

Discovered in 1782 by Pierre Méchain, French astronomer and colleague of Charles Messier, M107 was the last Messier object to be found, located in the constellation Ophiuchus, it lies close to the galactic plane at a distance of 20,000 light-years from Earth. It has the designation NGC 6171 in the New General Catalog.
The globular cluster apparently presents more obscured regions, unusual for such astronomical objects, it is densely concentrated in a volume that is only about 20x the distance between our Sun and its closest stellar neighbor.

The Dark Shark Nebula
Copyright: Jay Aigner LDN1235, The Dark Shark Nebula, shot at Cherry Springs State Park in Pennsylvania. It’s about a 12 hour round trip from my house, but I’d drive 10x that far to be able to shoot this incredible target in dark skies. This was shot back in June of this year.

This is about 8 hours of total integration time in L, R, G, B with my monochrome ZWO 294M camera and 115MM Meade refractor. EQ6R mount, ZWO EAF, ZWO OAG, and Astronomik LRGB Deep Sky filters.

Relaxation under the starry sky
Two friends I first met about half a year ago in the same place. Both passionate photographers who travel to Grun take pictures of the stars. Well, this meeting was very rare, but they shared the place and I then misused them as models in the photo 🙂

My goal was a clear, full-sky panorama at 35mm from the tracker for the highest quality photo. Such a novelty, which I did not dare to go into last night.
Canon 6Da + Sigma 35mm f / 1.4 + Skywatcher Star Adventurer + tripod

20 "> 25"> 30 "(from horizon to zenit due to darker sky)
ISO 3200

The landscape is 30 "f/2.5 ISO 3200 with the tracker off and in some places an extra photo for exposure bracketing.
Both panoramas blended together in Photoshop at 1:1 position.
Location: Staré Hamry, Czech Republic

This picture is my second ever on my new 1600mm pro. The elephant trunk nebula is one of the most beautiful objects out there in my opinion and this is my rendition of it.
This was captured with my 1600mm pro and ZWO 7nm narrowband (SHO) and processed in the Hubble palette. No calibration files.
Date captured: 7th and 10th of September
Scope: Sky-Watcher 150/750 PDS
Place: My aunts balcony just outside of Stockholm in a bortle 7-8 sky.

Ha: 5min x 12 + 10min x 14
SII: 5min x 10
OIII: 5min x 7

Processed in Pixinsight and GIMP
