Close up of M20 the Trifid Nebula. Located 9000 light years away in Sagittarius Trifid is a star forming nebula. It is a very popular subject for astrophotographers. This image was taken with our RiDK 700 in LRGB Hydrogen Alpha and Oxygen III to provide a detailed close up of the Nebula and surrounding gas clouds.

PN G136.7+61.9 is a planetary nebula in Ursa Major.

PN G136.7+61.9 is extremely faint planetary nebula with size of about 7 arcminute that was discovered in 2013 by analysing data from the SDSS spectroscopic survey. The Sloan Digital Sky Survey or SDSS is a major multi-spectral imaging and spectroscopic redshift survey using a dedicated 2.5m wide-angle optical telescope at Apache Point Observatory in New Mexico, United States. The project was named after the Alfred P. Sloan Foundation, which contributed significant funding.

This is the first colour image ever taken of PN G136.7+61.9 planetary nebula. In appearance, as well as low surface brightness, this planetary nebula could be called "Night Owl Nebula".

This image taken over several nights in May 2021.

Last astrophotography done mid-July on 5 straight nights.

This is Sh2- 119 show nebula from the Sharpless catalog, located in the Swan constellation.

Little photographed object, dark and H-Alpha gas areas and especially Oiii can be captured with long poses.

Especially since the moon was well present, so I used my L-Extrem filter to capture the signal from these two gases.

I used a PixInsight script from Zloch Team Astro (again thanks for all you tutorials if by chance you see this message..) to create a layer of Sulfure gas and mix all three layers into SHO - which results Interesting.

The 10 min posing times will have allowed me to be even more picky on my stationing and self-guiding. At this time we don't really have the right to ' about ' anymore.

A huge thank you to Yann Sty for all his tips: settings + treatment.

Solar activity continues and it seems that it is increasing, that is why we expect more solar landscapes like this, every day, every minute, a different landscape, you have to be there to capture it, here I managed to capture the solar activity of last July. 24 from Dallas, Texas.

A real challenge! Through the smoke of Canadian forest fires, during a full moon and under a Bortle 9 sky, I took this picture of the Tulip Nebula (SH2-101) with about 10 hours of exposure in SHO from Montreal. I struggled with the processing, especially to bring out the weak OIII signal…
Interesting thing here, we can see the Cygnus X-1 binary system (above the Tulip nebula on the picture). It is a high mass X-ray binary system, it is a galactic source of X-rays. It was the first source of this type to be considered as a black hole.

Image Description and Details :

The NGC 6188 emission nebula is found near the edge of an otherwise dark large molecular cloud in the southern constellation Ara, about 4,000 light-years away from us. Born in that region only a few million years ago, the massive young stars sculpt the fantastic shapes and power the nebular glow with stellar winds and intense ultraviolet radiation. The recent star formation itself was likely triggered by winds and supernova explosions, from previous generations of massive stars, that swept up and compressed the molecular gas. The field of view spans about four full Moons, corresponding to about 150 light years at the estimated distance of NGC 6188.

Image Description and Details : NGC 6744 - I started this project at the end of May, capturing data over a total of 10 nights. This intermediate spiral galaxy is bigger than the Milky Way, with a disk stretching 175,000 light-years across. A small, distorted companion galaxy is located nearby, which is similar to our galaxy's Large Magellanic Cloud. This companion, called NGC 6744A can be seen in the main galaxy's outer arm in the upper left of this image.

Image Description and Details :

Transit from Ganymede 25 July 2021
Average night conditions due to fine mist. The idea was to make a Gif of the Ganymede transit with at least 1 hour of duration, but due to fog the light conditions varied a lot, which would prevent having a homogeneous Gif.
Good thing Ganymede himself came out with good definition, note that especially in the image with the infrared filter the dark region of Edfu Facula at 2 am and the light region of Osiris at 6 am are perfectly distinguishable in the photo, which shows that they are not artifacts.
PS: The high resolution image of Ganymede was taken from the Virtual Planet Atlas.

Image Description and Details :

An ominous dark nebula rises against the a bright star field and glowing gasses, alongside the tail of the Scorpius constellation. The structure spans almost 40 light years and dust and gas collapse to form stars within this dark nebula. Also known as a cometary globule, the cloud is shaped by ultraviolet radiation from the very hot stars in NGC 6231. The ultraviolet light also illuminates the reddish glow of hydrogen gas. Hot stars embedded in the dust can be seen as bluish reflection nebulae. This dark nebula, NGC 6231, and associated nebulae are about 5,000 light-years away.

Image Description and Details :
Dear friends, we are pleased to present you our latest discovery!
PaRasMoMi-1 stands for: "Dana Patchick-Sakib Rasool-Sankalp Mohan-Utkarsh Mishra".
It was Discovered by all four of us in april 2021 and we tried to guess what this object could be using the data that was available online, no doubt this new discovery needs some good scientific study
PaRasMoMi-1 lies in the constellation Monoceros and is 5942 ly (light-years) away from earth.
It is near the Rosette nebula/NGC 2237 and is officially designated at Hong Kong/AAO/Strasbourg H-alpha planetary nebula database. Comprehensive database of all known planetary nebulae.
PaRasMoMi-1 is Potential Planetary Nebula candidate which officially designated at Planetary Nebula net and at HASH Portal. by Dr. Quentin Andrew Parker
and designated By Pascal Le Dû on Planetary Nebula dot net.
The size of this nebula is very big and that is around 26 arcmins
*(Almost same size of moon in terms of apparent size)*
We want to thank our friend Patrick Dufour who photographed this nebula for around 20hrs from his remote observatory in Chile. He used a 12" AG Optical RC Telescope and QHY 600 Mono CMOS camera with SHOLRGB filter to capture the region. Since the object was only visible in OIII we asked him to capture as much OIII as possible and Patrick did a great job by collecting the data quickly - as the object was close to the horizon.
Patrick supplied us with the data and I started examining it and created a few Continuum free images of OIII and H-alpha to really bring out the structure details.

Sakib and Dana i look forward to learn more from you
PaRasMoMi-1 object details:
PN-G: 206.2+00.6
Coordinates: 06:41:30.00 +06:16:30.00
Size: 26 arcmins (Almost apparent size of the moon)
