The M 101 Pinwheel Galaxy in LRGB with 2023 ixf supernova
M 101 is a very large, face-on spiral galaxy in the constellation Ursa Major, also known as the Pinwheel Galaxy.
M 101 was discovered by Pierre Mechain in 1781, and later the same year by Charles Messier.
M 101 has produced three supernovae in the 20th century: SN 1909A, 1951H, and SN 1970G, and now only a few days ago we can see supernova 2023 ixf in the NGC 5461 region.
Three nights of imaging in May 2023 from my home in Gérgal, Spain.

A single 5 minute shot of Comet Leonard, tracked. A single shot is a bit noisy, even calibrated with flats and bias frames. 135mm Sigma Art lens at f/2, ISO200, Nikon D810A on a Celestron CGEM2 mount, with PHD2 guiding on the comet itself. This worked well enough that I will have to move my setup to be able to get more shots, and I will have to look into stacking of comet shots, never done it!
M 82 Cigar Galaxy HaLRGB
Messier 82 was discovered in 1774 by Johann Elert Bode, rediscovered by Pierre Mechain August 1779 who reported them to Charles Messier, who added them to his catalog in 1781.
M 82 is the prototype irregular starburst disk galaxy. In the core of M 82, the active starburst region spans a diameter of 500 parsecs.
Tendrils of material extend away from the nucleus, suggesting a colossal explosion. Studies have revealed filaments expanding outward from M 82 at 600 miles per second.
Imaged over 5 nights from my home in Gérgal, Spain.

At a not-so-busy night, I went to dark mountains and tune my larger equatorial mount (Tak's NJP) with a telescope 1m focal length.
Guiding parameters for diurnal motion is not completed yet and star image is not true circular in this photo. The problem, however, gets gradually to converge, I think :-)
The Pleiades star cluster, a night sky object that is pretty easy to see by eye currently! This is one night of data at Bendleby, 6 frames at 5 minutes each for red, green and blue filters, then the rest of the night with the luminance (monochrome) filter. RASA8 f/2 telescope, QHY268M camera, Celestron CGEM2 EQ mount, NINA control software, PHD2 guiding software, stacking and initial processing in APP, final processing in Photoshop. This target has lots of bright stars, which brings out the worst in my cable placement issues! Other than ugly stars, and more data needed for less noise, pretty happy with how this turned out!

The Sculptor Galaxy is an intermediate spiral galaxy in the constellation Sculptor and a stardust galaxy, which means that is is currently undergoing a period of intense star formation.
The Galaxy was discovered by Caroline Herschel in 1783 during one of her systematic comet searches.
The Sculptor Galaxy is located at the center of the Sculptor Group, one of the nearest groups of galaxies to the Milky Way.
It is the brightest one in the group and one of the intrinsically brightest galaxies in the vicinity of ours, only surpassed by the Andromeda Galaxy and the Sombrero Galaxy.

Portion of the Eastern Veil Nebula also known as Caldwell 33, whose brightest area is NGC6992.
The Veil Nebula is a cloud of heated and ionized gas and dust in the constellation Cygnus.
The Nebula was discovered on 1784 by William Herschel.
Given a distance of 2400 Light Years, this gives the radius of the entire nebula as 64 Light Years.
Undulations in the surface of the shell lead to multiple filamentary images, which appear to be intertwined.

Messier 81 (also known as NGC 3031 ) is a spiral galaxy in the constellation Ursa Major.
Messier 81 was first discovered by Johann Elert Bode on December 31, 1774. Consequently, the galaxy is sometimes referred to as "Bodes Galaxy".
Messier 82 (also knows as NGC 3034) is a starburst galaxy in the constellation Ursa Major.
Messier 82 is commonly referred to as the Cigar Galaxy.
Ursa Major is approximately 11.7 million light years from Earth. The distance from M81 to M82 is 150,000 light years.
M81 and M82 are best seen during the spring.

I wasn't happy with how my RGB only Cone Nebula turned out so I got a night's data of hydrogen alpha (Ha) using a 12nm Ha Astronomik filter. The difference in exposure between RGB and Ha, even 12nm, is huge, I went from 10 minutes at ISO200 to 20 minutes at ISO1600 and was still a bit underexposed in the Ha. Anyway, I used the Ha data as 25% luminance in APP, makes quite a difference! Nikon D810A, 600mm focal length, f/4 focal ratio, ISO1600, 20 minute subs, Celestron CGEM2 mount, PHD2 autoguiding, APT camera control, APP for stacking and initial processing including star reduction, final processing in Photoshop.
I had some different ideas about how to edit this data from July 2020, so I went back to the original integration in APP to create a new stretched version, then tried a different style to my original edit in Photoshop. The data was from 10 minute shots, stacked in APP. 40mm Sigma art at f/2.8, ISO 200 on a Nikon D810A, mounted to a Celestron CGEM2 GEM, guided using PHD2, controlled by APT.
A section of the Milky Way core with the Prawn Nebula and Fighting Dragons of Ara. This didn't turn out as I hoped, there are just so many stars in this region! Single panel, 135mm Sigma Art lens at f/2, ISO200, 10 minute subs (13 of them), Nikon D810A on a Celestron CGEM2 EQ mount, guided y PHD2, camera control with APT, stacking and initial processing in APP, final processing in PS.
i'm now into astrophotography for about 4 years now (15 months with telescope) and never experienced what happened to me this week - three consecutive nights with clear sky, no wind, no moon!
this gave me the opportunity to shoot two nights with my Optolong L-Enhance dual narrowband filter and one night without (for star colors). unfortunately, i still haven't bought a 0.8x reducer so this nebula did not fully fit the frame :)

The Bubble Nebula is an emission Nebula in the constellation Cassiopeia. It lies close to the direction of the open cluster Messier 52. The "Bubble" is created by the stellar wind from a massive hot, 8.7 magnitude young central star. The nebula is near a giant molecular cloud which contains the expansion of the bubble nebula while itself being excited by the hot central star, causing it to glow.
The Bubble Nebula was discovered in 1787 by William Herschel.

Re-processed 2.3 hours of old data taken a while ago, RGB only, 70-200mm f/2.8 lens at 200mm, some at f/2.8, some at f/4, some at 720 seconds, some down to 120 seconds. I was experimenting with trying to HDR the stars a bit but this time I just lumped all the different exposures into APP with auto integrate, mostly it did pretty well but there is some nasty artifacts around the brightest stars. I really need a lot more data to get this cleanly I think, but mostly pretty happy with how APP did this. D810A, Celestron CGEM II mount, PHD2 guiding, APT camera control. Photoshop for final editing.
This bright emission nebula in the constellation Cassiopeia is 9,459 light years away and is named because of it's similarity to the famous video game character.

I added some more data to my Rho and Blue Horsehead shot as well as a couple new panels capturing a big bright pink area of Ha and a whole heap more dust. I need more data for this area to eliminate the satellite trail at the bottom. 21 hours of data in this in 10 minute subs, Nikon D810A, 135mm Sigma lens at f/2 (no RASA needed!) ISO200, Celestron CGEM2 EQ mount, Astrophotography Tool camera and mount control, PHD2 autoguiding, stacked, registered and integrated in Astro Pixel Processor with final touches in Photoshop.
Okay, final experiment with channels (for now!) This one used the RGB unfiltered data for colour, but I made a grayscale luminance channel from the UHC data which has the effect of reducing the star size and increasing the nebulosity a bit, but over a broader range than the Ha data and with larger stars than the Ha as luminance but smaller than the RGB mixes. What do you think?
Nikon D810A, mostly 10 minute exposures, 600mm f/4 VR, Astronomik UHC filter, Celestron CGEM II EQ mount, ZWO guide camera, PHD2 guide software, Astrophotography Tool camera control, ASTAP plate solving, Astro Pixel Processor for stacking and registration, files combined and edited in Photoshop.
NGC6188, The Fighting Dragons in Ara.
The Orion Nebula can be seen with the naked eye in dark skies and is located in the belt of the Orion constellation.
This image actually consists of several catalogued objects including:
M42 the Great Orion Nebula
M43/NGC 1982 de Mairan's Nebula
NGC 1977 the Running Man Nebula
The Trapezium cluster
Technical stuff:
iOptron CEM70 mount
Canon 7D Mark II (ISO1600) + Canon EF 600mm f4 L IS II (f4)
Optolong L-Pro filter
Primaluce 60mm guidescope + ZWO ASI290MC
Capture software: APT + PHD2
25 mins of 2 minute exposures + 20 10 second exposures (blended in PS)
Stacked in DSS
Processed in Photoshop + Topaz Denoise
The Horsehead and Flame Nebulae and surrounds in Orion. This is more data added to an existing shot I had and processed a little differently. 10 minute shots, Nikon D810A, Sigma Art 135mm at f/2, ISO200, mounted to a Celestron CGEM2 EQ mount, guided by PHD2, camera and mount control with APT, stacking and integration and star reduction in APP, final edit in Photoshop. I used a few 60 second shots for a bit of HDR on the Orion nebula. I also got overlapping panels surrounding this frame with the intention of getting a bit more of a flat field for this view but these shots could not be integrated in APP for some reason, I kept getting errors after hours of processing so in the end I didn't use any of those shots at all!
The Vela Supernova remnant in the Milky Way, this is not very bright but takes up quite a patch of sky, this is with a 135mm lens shot at f2.8 and f2 on my D810A, About 5.5 hours with no filter, I did try using some older Ha data with this but prefer the RGB. Shot in the backyard at Hawker, South Australia, 10minute subs, ISO200, APT controlling the camera, PHD2 with multi star guiding controlling the CGEM2 GEM, stacked in APP with final edits is PS.
The Dumbbell Nebula (also known as Apple Core Nebula, Messier 27, M27, or NGC 6853) is a planetary nebula in the constellation Vulpecula, at a distance of about 1227 light-years. This object was the first planetary nebula to be discovered by Charles Messier in 1764.

Thank you for your comments,

my third try, the second with my telescope and the first picture i processed with APP (astro pixel processor).
everything was awesome this night - no clouds, perfect seeing, no wind, no moon. i personally would say that this is one of my best astro images so far, but still there's much to learn :)
