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 The Apennines stretch a total length of about 600 km and the mountain peaks reach heights of 5000 m. The slopes towards Mare Imbrium are relatively steep with slopes of approximately 30 °, while on the opposite side, towards Mare Vaporum and Sinus Aestuum they are significantly less.

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)

Image Description and Details :

I compiled shots of this target for as many nights as I could over the past 4 years. Each time stacking and feeling it's not enough... I'm in Michigan, Bortle 7.5. Home of "lake effect clouds" and I might get 5 clear nights over the period that this target appears in my sky.
I shot over 4 years with 3 different scopes and 3 different cameras and combined my efforts this last spring and this was the result.
I hope to collect more should I find another clear sky here in the winter.

Image Description and Details : It seems quite appropriate that this very bright globular cluster is located in the constellation of Pavo - the Peacock. The bright scattering of stars look like the fine display of a peacock's tail when it is trying to impress a prospective mate. This globular cluster does a very fine job of that as well.

According to Wikipedia, NGC6752 is the fourth brightest globular cluster after Omega Centauri, 47 Tucanae and Messier 22. I already have images of Omega Centauri and 47 Tucanae so now I'm going to have to grab some data on Messier 22.

Approximately 6 hours of data collected for this image with a TSA120 and QSI 683 CCD.
