Image Description and Details : My last image is a Bubble nebula (NGC 7635) with SHO narrowband channel and added RGB stars.
It is an emission nebula located in the constellation of Cassiopeia. The central bubble is one of three layers of hot gas surrounding the star SAO 20575, a very hot O6.5-class star. Curiously, this star (which is the one that heats the gas so that it emits light), due to its rapid movement, is not in the geometric center of the bubble. It is seen in the lower left area of the center of the bubble. It is a very young star (about 4 million years old...) and is expected to explode as a supernova in about 15 million years (more or less a million...). Interestingly, this nebula is located in a region where another supernova has already exploded.
It's great a lot of signal of SII, and aprecciate a large structures between bubble.

Image Description and Details : Pleiades (M45)
Open Star Cluster

Magnitude: 1.6
Distance: 444 ly
Constellation: Taurus the Bull

A beautiful and mesmerizing deep sky objects that is etched on several folklores and mythology. This open star cluster is dominated by hot luminous B-Type stars that formed a 100 million years ago and is not gravitationally bound that will eventually drift apart. Pleiades stars are passing through a dust cloud and is completely unrelated reflection nebula. Scientist has found over a 1000 stars in the region. Pleiades is easy to find visually and is also a reference object in finding other deepsky targets.

Image Description and Details : WHTZ1 is an obscure, very faint but complex high-excitation planetary nebula in Aquila. It has a size of 193 arc seconds.
It was discovered by Ronald Weinberger, Herbert Hartl, Sonia Temporin and Caterina Zanin in 1999. It was also independently discovered by the French amateur astronomer Thierry Raffaelli in 2014 and is also known as Ra 7. It has also been discovered on two further separate occasions by the Deep Sky Hunters members Dana Patchick and Matthias Kronberger. The limb brightening visible towards its northern edge suggests interaction with the interstellar medium.
This is only the second time that it has been imaged - the previous image by the CHART32 team.

Image Description and Details : NGC 281 - This awe inspiring emission nebula in Cassiopeia contains an open cluster accompanied with several Bok globules that appear to swim in a cosmic ocean rich in molecular hydrogen, sulfur and oxygen. Captured over several nights throughout late August and early September, more than 21 hours of the very best 12 minute subs were selected to reveal the exquisite detail in this mesmerizing region of the night sky.
Last year, I watched James Negri on the DSO Imager channel process this image. I was so impressed with James's image that I decided to add the Pacman Nebula to my list of objects to capture in 2022. The data was surprisingly clean and bright which was a pleasure to process.

so here's my latest take, it's SH2-129 - OU4, known as:

- SH2-129 Bat Nebula in flight and

- OU4 giant squid nebula, discovered by French amateur astronomer Nicolas Outters.

- For this treatment, I wanted to keep some transparency from the squid, allowing the gases in the background to be distinguished, which gives a sense of depth.

- I also preferred a gentle treatment on the whole Squid to avoid a cupboard thing in the picture as well.

NGC 1097 is a barred spiral galaxy 50 million light years away in Fornax.

There are a number of interesting features

The galaxy contains a super massive black hole 140 million times greater than our sun. The black hole is surrounded by a ring with numerous areas of star formation. The ring is lit by an influx of material moving towards the central bar of the galaxy.

The galaxy contains four optical jets (one of which is extremely faint) that seem to emanate from the nucleus region. Studies have determined the jets are not emissions but are made up of stars.

There are two satellite galaxies NGC 1097 A and B. A is a peculiar galaxy which is orbiting only 42000 light years from the center of NGC 1097 while B is a dwarf galaxy which was discovered by emissions and has not been well studied.

Image Description and Details : Our fifth sky target, a wide field of 4 tiles in the constellation Cepheus with the Iris Nebula (NGC7023) and the Ghost Nebula (VDB141). To date, it remains our most ambitious and complex project in terms of acquisition and processing.
This constellation Cepheus in the Milky Way is sublime because it is dotted with bright and dark nebulae, which show superb colors and contrasts. In addition, many molecular clouds (IFN) line the constellation forming coffee-colored arabesques.
The full image corresponds to a mosaic of four tiles (with LRGB layers), which represents a total of 90 hours of exposures over approximately 35 nights, including 50 hours in Luminance (around 12 hours per tile) and 40 hours in RGB ( therefore 10 hours per tile).
Two crops were produced on L'Iris and le Fantôme.

Image Description and Details : The Shark Nebula is a deepsky object I've tried to image a few times and never had much success. It is faint and challenging both in acquisition and processing. It requires a lot of moonless nights to really make the nebula region pop and to bring out the colours. This latest attempt to image it I employed different equipment than I usually use. For years I've used refractors to image the night sky but for the Shark nebula project I used a Starfield Optics 8 inch astrograph with a Starizona reducer/corrector which makes it an F3 light collecting beast! This combination worked very well on this target and I'm really happy with the final image. There is a lot to see in this image including LDN1235, VDB 149, VDB150 and galaxy PGC 67671. It's an interesting region of interstellar gas and dust sculpted by massive stars and their fast stellar winds and light energy.

Image Description and Details : The Elephant's Trunk nebula is a concentration of interstellar gas and dust located in the constellation Cepheus about 2,400 light years away from Earth. The Elephant's Trunk is composed of cool interstellar dust and gas, which blocks out light on its way to Earth and leaves behind a long, thin silhouette that gives the nebula its name, and makes it one of many nebulae that look like animals. Imaged here in what is known as the Hubble palette of colours on can clear make out the many gases which form this very interesting deep sky object….

Image Description and Details : This August, we have been fortunate to have had many clear nights up in Southwestern Ontario Canada. This mysterious looking target has been on my list for a while. Instead of capturing a widefield image, I chose to get close to reveal the faint detail surrounding this nebula. I processed the data in both SHO and HOO and then blended them together to create a unique and rich colour palette.

Image Description and Details : Sh2-129, also known as the Bat Flight Nebula, is a region of HII-type nebula emission located about 1,300 light-years from Earth in the constellation Cepheus. We can see another nebula, the Squid Nebula (Ou4), located at a distance of about 2300. It is a very weak nebula and requires many hours of integration to be able to appreciate it.
