Deux tentatives réussies de capturer la comète C/2013 R1 Lovejoy. Malheureusement, la queue ne se détache que très mal du fond du ciel. Les raisons peuvent être le début de l'aube et la présence de la Lune presque pleine. Je tenterai de combiner les 10 fichiers d'assez bonne qualité avec Deepskystacker ou IRIS.
Two attemps of capturing Comet C/2013R1 Lovejoy. Unfortunately, the comet's tail doesn't detach that clearly from the background sky. Reasons can be the approaching dawn and the almost full Moon, which was that far in the sky (roughly 90°). I will try to stack the 10 good files I made in Deepskystacker or IRIS.

Wow, this one is a stretch, but I hereby claim two more galaxies in my imaging empire! The larger galaxy at the bottom is Messier 81, the smaller one M82. Together, they are sometimes referred to as Bodes's Nebula. It's not much of an image... I'll do better next time!
Taken under the beautiful dark skies of Killarney Provincial Park, Ontario.

THIS PHOTO WAS JUST FOR FUN, to see what this well-known star cluster would look like from a terrible astrophotography location!
Sun 13.5° below the horizon
Altitude of M45 at time of exposures: 54.6°
______________________________________________
Description:
This most famous of all open star clusters is readily visible to the unaided eye even in the middle of a light-polluted city. Morning twilight was starting to creep into the eastern sky when I grabbed the subframes to make this image, so the sky was starting to turn a little blue.
Even though the subframes from which this stacked images were made were only 10 seconds in length, at ISO 200, stars to 14th magnitude can be seen if you look carefully.

This is a faint but relatively large PN in the constellation of Lynx. Since my telescope is only f/8 I had to gather a (for me) substantial amount of exposure time. Unfortunately, due to time constrains and the weather, I couldn't finish the project in one season, so this is the result of 3 nights of imaging done in 2 years (9/4/2021, 1/4/ and 19/4/2022).
Imaged through my usual 8 inch GSO RC I collected 31x10 minutes of data on this PN. Camera was a cooled EOS 700Da, filter an Optolon L-eNhance. Unfortunately, I had issues getting rid of artefacts by the amplifier glow, although I made new and correct dark frames. Instead of trying to fix it through processing, I simply cropped the image.
Stacked with DeepSkyStacker in sigma clipping mode (incl. dark, flat and bias correction with no factorisation of the colour channels), further processed with Fitswork (background neutralisation, alignment of RGB channels), Affinity Photo (curves and contrast, saturation) and Noiseware (noise reduction).

"Darkness falls across the land
And the first stars twinkle into sight
And the moon on the trees is beautiful
But not so lovely as you
But not so lovely as you
Day to day we work away
To earn the time to make for play
So rare to take the time to sit
And stare into your eyes
And stare into your eyes
Before I found this place with you
My heart was kept inside a cage
But now it flies on feathered wings
And finds its way to you
It finds its way to you
My love for you, it's like a river
It runs and falls and goes on forever
I can't see around each bend
But still I love you more
But still I love you more
Darkness falls across the land
And the first stars twinkle into sight
And the moon on the trees is beautiful
But not so lovely as you
But not so lovely as you"

it is especially hard to photograph the Milky Way here as the Galactic Center never rises above 19 degrees. The weather was not perfect (humid, low clouds) but with stacking of 55 overexposed shots (5 sec exposure, F/1.8, ISO 1000) and heavy post-processing I finally managed to get some details.
The Andromeda Galaxy in Andromeda - M31. 10 November 2010.
Everyone has a go at this! 2.5 MILLION light years away! More difficult than you expect. Unguided, 24 x 1 minute exposures, stacked in Deep Sky Stacker, dark frame subtracted. Processed in CS5.
I might have a go at getting slightly longer exposures next time for more detail, but unguided it's difficult.

A stacking of 9 light, 11 dark, and 9 bias frames with DeepSkyStacker.
I'm not completely sure what the "scratches" are in the image, but they don't appear anywhere in the source images. The "blotchiness" in the sky is caused by mixtures of clouds overhead as a result of the stacking process. I should redo with no clouds :(
I plan to add a few more nights of data to this and present a more widefield view.

Since I think I am at the limit of what is possible with the Andromeda Galaxy without a means of tracking, I thought I'd switch targets.
The next obvious thing to try was the Pleiades, so here's the result of tonight's exposure stacking. Around 180 two second exposures @ ISO 1600.
Just a hint of the reflection nebula, particularly around Merope.
While the telescope is collecting it's data with Canon 6D attached, the Canon 5D mk2 with 16mm lens took 20, one minute pictures around 03 am today. Stacked in DeepSkyStacker (no alignment and HDR selected)
Seen over Otmoor (UK) on the night of Sunday 19 July.
This is a stack of 68 frames at 100mm f4.5 and 2s - using DeepSkyStacker.
You (well, I!) can just make out the ion tail going straight out, slightly to the left of the diffuse, curved dust tail. The sky doesn't get super dark around here, so it was hard to get enough signal - plus on reflection I should really have used my f2.8 100mm lens rather than the 100-400mm!

The comet is now large enough for me to image at 50mm (where the tracking requirements are a lot more forgiving). I was planning to go really deep to see if I could pull out the faint outer halo and the short tail, but the freezing cold put paid to that idea.
Best viewed large. The small version really doesn't do it justice.
I wasn't going to post this.
I have processed this thing to death, stretched it far too much, and clipped it in all sorts of places, but having said all that I'm sort of pleased. At least you can see what it is!
Had terrible trouble with ice (Saturday night) and had to bin most of the subs as Alnitak looked like it was peering through frosted glass (even more so than it does now), so this is just 16x60second frames (hence the reason I had to stretch it to death). I took 90. Also the master dark didn't fit anymore as I took the darks at the end (all iced up!)
My next attempt will be better (I hope)

As hard as I tried, this was about the best I could get from Phoenix. From a Bortle 6 zone, I captured 500 2 second exposures of C/2020 F3 #NEOWISE, the #neowisecomet, on July 18th from 9-9:40pm. I ended up with a massive .tiff file and not a whole lot of detail for my trouble :/ I think I was just too late to the party (Neowise was much brighter a few days prior), and was shooting through too much light pollution, atmosphere, and haze.

Cropped from a DSS stacked image using some shots that I captured yesterday using an unmodified Canon EOS 60D mounted onto a Skywatcher 200 reflector in a light polluted city suburb. No guiding or filter used. Photoshop CS6 used to process the stacked image of 237 frames (ISO 2500;15 sec exposures).
From Wikipedia: “The Crab Nebula (catalogue designations M1, NGC 1952, Taurus A) is a supernova remnant in the constellation of Taurus. The now-current name is due to William Parsons, 3rd Earl of Rosse, who observed the object in 1840 using a 36-inch telescope and produced a drawing that looked somewhat like a crab.[5]Corresponding to a bright supernova recorded by Chinese astronomers in 1054, the nebula was observed later by English astronomer John Bevis in 1731. The nebula was the first astronomical object identified with a historical supernova explosion.”
Canon 550D with Celestron CGEM 1100HD. ISO 800 with 15 minute exposures plus 15 minutes dark frame for each shot. Stacking of 7 shots taken 2012-03-17 (1/2 hour per shot) using Deepskystacker. Post processing including gamma curve, brightness and overall contrast adjust using Canon DPP. Manual guiding using Celestron's off-axis guider and Orion's 12.5mm illuminated reticle eye piece.
Did one with the CPC 800 last year, using the 11: scope, this one seems to have more resolution and clarity - however, I need more stacks, too much grain in the nebulous areas.
UPDATE: Added 8 more to the stack 2012-03-24 to bring it to 15 total.
Sh2-252, nota talvolta anche col nome proprio Nebulosa Testa di Scimmia, è una nebulosa a emissione visibile nella costellazione di Orione. Si trova nella parte settentrionale della costellazione, al confine coi Gemelli. La sua declinazione non è particolarmente settentrionale e ciò fa sì che essa possa essere osservata agevolmente da entrambi gli emisferi celesti, sebbene gli osservatori dell'emisfero boreale siano leggermente più avvantaggiati; il periodo in cui raggiunge la più alta elevazione sull'orizzonte è compreso fra i mesi di novembre e marzo. Sh2-252 è una grande regione H II estesa per circa 25' situata entro i confini della costellazione di Orione, distante circa 6.500 anni luce dal sistema solare.

Prologue
In the constellation of Cygnus
There lurks a mysterious, invisible force
The black hole
Of Cygnus X-1
Six stars of the northern cross
In mourning for their sister's loss
In a final flash of glory
Nevermore to grace the night....
1
Invisible
To telescopic eye
Infinity
The star that would not die
All who dare
To cross her course
Are swallowed by
A fearsome force
Through the void
To be destroyed
Or is there something more?
Atomized — at the core
Or through the astral door —
To soar....
2
I set a course just east of Lyra
And northwest of Pegasus
Flew into the light of Deneb
Sailed across the Milky Way
On my ship, the Rocinante
Wheeling through the galaxies,
Headed for the heart of Cygnus
Headlong into mystery
The x-ray is her siren song
My ship cannot resist her long
Nearer to my deadly goal
Until the black hole —
Gains control....
3
Spinning, whirling,
Still descending
Like a spiral sea,
Unending
Sound and fury
Drowns my heart
Every nerve
Is torn apart....

The brightest star in this pic is Jupiter. Dwarf planet (1) Ceres is also well visible in this image, but excuse me for being too lazy to label it out. The total exposure is less than the expected because I had to stop taking photos due to increasing obstruction of a treetop, which has been largely removed by the median algorithm. The only remaining artefact is that it causes a faint dark splodge near the bottom right corner, though people may not be able to discern it whatsoever. It can certainly be removed completely by discarding the last several images which have the treetop, but this will reduce the overall total exposure time so I will just leave it there.
