The M81 and M82 galaxies are a pair of galaxies located in the constellation Ursa Major.
M81 (also called the Bode's Galaxy) is a spiral galaxy that lies approximately 11.8 million light years away from us, its size is approximately 45000 light years.
Its neighbor, M82 (The Cigar Galaxy) is an irregular galaxy at roughly the same distance away from Earth, this Galaxy measures about 18500 light years.
It took me 5 nights to take this picture. 3 nights with the L-PRO Filter & 2 with the L-Extreme filter. (to get the Hydrogen Alpha / Red)
As it was the last possible target for me before the Galaxy Season, I decided to increase the exposure time and tried to get some Integrated Flux Nebula (IFN) but it was too faint and the light Pollution won the battle.
I'll try to get longer exposures next year (10min or maybe 15 min) as a last try to get this damn IFN.
So, as the IFN was not for this year, it was time to drizzle and check the result. It took me a few attempts to get this result, but in the end, I'm very pleased with the result as the galaxies take up a little more space into the frame. :)
(The stacking Process freezed my computer for almost 5 hours, but it was worth it)
(I put the originally non drizzled picture at the end of the Slide Show)

La Galaxie IC342, ou Caldwell 5, est une galaxie spirale intermédiaire située dans la constellation de la Girafe à environ 11,4 millions d'années-lumière de la Voie lactée.
Cette galaxie serait beaucoup plus brillante dans le ciel de la Terre si elle n'était pas située près du plan de notre galaxie et cachée à notre vue par des nuages de gaz et de poussière. (wikipédia). C'est pour cela que la Nasa l'appelle la "Galaxie cachée".
IC 342 (Caldwell 5) is an intermediate spiral galaxy in the constellation Camelopardalis (wikipedia). The Nasa called it the "Hidden Galaxy", since it's located behind dusty areas near the galactic equator, so it makes it difficult to observe.

The image include 67 x 2-minute exposures at ISO 800 using a Canon 60Da DSLR camera.
The telescope used was a William Optics Zenithstar 73 APO, which is quickly becoming one of my all-time favorite scopes.
Unlike when shooting from home, I was able to swap a light pollution filter for a UV/IR to collect natural colors. Man, so much more enjoyable to process!

I do really like this parts of the sky but it has been hard to process because of the light pollution.
Despite of the light pollution caused by the position of these galaxies in the sky, considering my position, I like the work done by the QHY168C camera this time - over 2 nights of expsosure time.

This is the faint emission nebula designated as IC 1396 in the constellation Cepheus. This region is energized by the bright, bluish central multiple star HD 206267. You can see the Elephant’s Trunk Nebula, IC 1396A, on the lower edge of this image. From NASA APOD, “Stars could still be forming inside the dark shapes by gravitational collapse. But as the denser clouds are eroded away by powerful stellar winds and radiation, any forming stars will ultimately be cutoff from the reservoir of star stuff.”

NGC 6979 is a part of The Veil Nebula (Cygnus Loop) a cloud of heated and ionized gas and dust in the constellation Cygnus and it's a large supernova remnant. The source supernova was a star 20 times more massive than the Sun, and it exploded between 10,000 and 20,000 years ago.The remnants have since expanded to cover an area of the sky roughly 3 degrees in diameter (about 6 times the diameter, and 36 times the area, of the full Moon). It's estimates distance is from 1200 to 5800 light-years from earth,

The Veil Nebula - NGC 6960
The Veil Nebula is a supernova remnant located 2,100 lightyears away in the Cygnus constellation that spans 110 lightyears across.
A supernova remnant is the remains of a star that has ended its life in an explosion known as a supernova. In the case of the Veil Nebula, the star in question was 20 times the mass of the Sun and exploded about 8,000 years ago.
A blast wave from the stellar explosion is hitting cooler, more dense interstellar gas and emitting light in the process.
The Veil Nebula is part of the larger Cygnus Loop structure, and the delicate filaments and almost fragile-looking structure are what give the Veil Nebula its nickname.
The Western Veil Nebula (Right), NGC 6960, is also known as the Witch’s Broom, due to its long, thin, raggedy appearance.
The Eastern Veil (Left), also known as NGC 6992 and Caldwell 33, contains NGC 6995, or the Bat Nebula.
Together, NGC 6992 and NGC 6995 are collectively known as the Network Nebula.
Just above the Western Veil you’ll find Pickering’s Triangle, named after the American astronomer Edward Charles Pickering who in the late 19th/early 20th century headed Harvard College Observatory.
To be honest, I was not supposed to post it before Galaxy Season for many reasons. Stars Pinched by the Focuser Lock, Shooting during a full Moon and the fact that the framing/dithering was really annoying with the AZ GTI in Equatorial mode.
But the Cloudy Situation changed the game, as usual. So I decided to resume the processing for this picture. Here is the result of 2 nights in July, during a full moon, in a light polluted sky.
Next time, I'll take my revenge on it :p

AstroPixel Processor took almost three hours or maybe even longer !!! to stack the data and construct the mosaic as I had MBB and LNC (1 iteration ) turned on
Very disappointing to see the star shapes in the corners- I thought I had found a good edition of this lens- and have previously obtained photos with it where star shapes have not been a huge issue. What's different? not sure- the only thing that has changed is the filter - a UV/IR filter instead of a L extreme filter. Could this cause the problem ? not sure
the h alpha regions don't "pop" as much as maybe could be expected... maybe H alpha data would improve the image. Something to try another day
Before 10,000 years a supergiant star exploded to shine like a Moon in the sky for weeks. This stellar explosion is called supernova that lead to formation of emission nebula called Veil nebula. The nebula distance is about 2,500 light years from us. Its composed of 3 parts, the Eastern part is called Network nebula in the lower part of the image, the middle part is called pickering triangle and the third part is the Western one called Witch’s Broom or finger of God nebula which appears on the upper part of the image. The Red colour is ionised Hydrogen gas and the teal Blue is excited Oxygen gas.

I had four night clear so I thought would try a 4 shot panorama of this cloud SGP showed me a nice square mosaic but in reality the end result was more like + sign than a square.
4 night 82 shot each night to make a panel out of each night, 4 panels added to PTGui to get the final panorama of the area. this is the end result the main center part only.
I would have been better taking the area with my Nikon 300mm lens as a single shot than try and make a mosaic again. I will try to do that as the SMC is sitting in the right place.
82 shot 7 1/2min each in as much clear night as I could get.

Located in the constellation Cepheus and probably better known as the Wizard Nebula. I have to say, from the perspective we see it from 7,000 light years away here on Earth, it does look like a wizard wearing a pointy hat in a robe with baggy sleeves.
The NGC number 7380 is actually for the young 5 million year old open star cluster that has formed within the nebula.
Do you see the wizard in the image?

This large star forming region is called the Soul Nebula (or Embryo Nebula) and is found in the constellation Cassiopeia. This nebula is often shown next to the Heart Nebula (IC 1805). The Soul Nebula is about 6,500 light years away from Earth. The nebula contains several open clusters and there are few smaller emissions nebula around the perimeter. The star clusters are surrounded by hydrogen, which glows red from the young hot stars nearby.

The pinwheel is a face on spiral galaxy found in the constellation of Ursa major, the great bear. Which is a circumpolar constellation, meaning that it never sets below the horizon in the Northern hemisphere.
21 million light years away and some 170,000 light years in diameter, the galaxy is estimated to contain upwards of one trillion stars. It was first observed by Pierre Méchain on the 21st of March 1781.
M101 is just about visible through a pair of 10x50 binoculars under a dark sky with the right conditions. Though a telescope of 6" and above would be preferable.

SH2-157, also known as the Lobster Claw Nebula, is a bright emission nebula located about 11,000 light-years away in the constellation of Cassiopeia.
I started imaging this target in November 2024. Unfortunately, due to bad weather, I haven't been able to get back to it as it has now disappeared behind a large tree on the North/NW. I may get back to this target in 2025.
I acquired this image with:
* William Optics FLT132 telescope with the FLAT8 0.72x reducer/flattener.
* ZWO 2600MC Pro camera.
* Antlia ALT-P dualband 5nm Ha & Oiii filter
* Optolong L-Ultimate 3nm Ha & Oiii filter.
* ZWO AM5 mount with ASIAir plus.
Pre and post processed in PixInsight and Affinity Photo 2.

Here's my interpretation of the well-known Rosette Nebula. It's a composite of images over two nights from my back yard in suburban Bloomington, Indiana. It includes images made using two filters that primarily isolate the light emitted by the elements sulfur (red), hydrogen (emitted as red but shown here in green), and oxygen (blue), similar to many of the images of such objects made by the Hubble Space Telescope.
This is another vast region of dust and gas, mostly hydrogen, excited to glow by the bright, hot, young stars in the center. Another generation of stars is undoubtedly forming in the denser areas of remnant material. This includes several catalogued objects including NGC 2238, NGC 2239, NGC 2244, and NGC 2252.

This is the nebula rich region in the constellation of Monoceros the Unicorn with the dark Cone Nebula (left of centre) and the small V-shaped and bright Hubble’s Variable Nebula at bottom, a reflection nebula that varies in form and brightness. Above the Cone Nebula is the triangular Christmas Tree Cluster, NGC 2264, here upside down as the bright blue star 15 Mon is the base of the tree. The large region of nebulosity is Sharpless 2-273. The V-shaped dark nebula above centre is LDN 1603.
Near 15 Mon is a blue reflection nebula. Another blue reflection nebula IC 2169 and associated star cluster Collinder 95 is at left — I framed the field to contain this nebula. Other bits of reflection nebulosity surround it - clockwise: NGC 2245, NGC 2247 and IC 446 above the main nebula. The rich faint cluster near centre is Trumpler 5.
This is a blend of 8 x 5-minute exposures at ISO 800 unfiltered with 6 x 8-minute exposures at ISO 1600 shot through an Optolong L-Enhance dual-band nebula enhancement filter (it lets through only Oxygen III blue-green and Hydrogen-alpha red to really enhance the nebulosity). All exposures with the Canon EOS Ra mirrorless camera through the SharpStar HNT150 Hyperbolic Newtonian Astrograph at f/2.8, from home on a very clear moonless night January 26, 2020. All stacked, aligned and blended in Photoshop 2020.
