M51 - The Whirlpool Galaxy
Easily one of the most photographed deep sky objects, M51 never ceases to amaze me. My first ever astrophoto in 2012 was of this galaxy, and I've shot it pretty much every year since, constantly improving on what had come before. This year was no different other than the amount of data I had.
I shot this over many nights in the spring and early summer despite having a lot of cloud cover to deal with. Overall, I had about 12 hours of data, but much of that didn't quite measure up due to clouds blowing through, deteriorating my images. It look me quite a long time to go through hundreds of images manually to weed out the obviously bad stuff until I had just shy of 8 hours of data. Then finally in stacking, I whittled that down even further.
This is the final image with 6 hours, 10 mins of data made up of a mix of 3 and 5 minute exposures.

Helix nebula (NGC7293), hAlpha, 36 h total exposure time with Hyperstar 14"/F1.9 with ASI 1600 and RASA 11"/F2.2 with ATIK 460, parallel mounted on a ASA DDM85. Single subframe exposure time between 90 sec unbinned for the center structures and 180 sec 2x2 bin for the faint environmental veils. I am very happy how many structures of the environment are getting visible. I look forward to your feedback! Tenerife November 2017.
Now the colour version. During the "Perseid night" I had a lot of luck (and maybe also a kind of skilled serendipity). Tons of luck indead that the meteor is captured in both systems (regarding the 10 sec+ CCD downloading time which is an effective exposure pause). Through the middle of a relatively tiny sky area (FOV 7. 2 x 10. 8 °) I could capture this meteor (which is, however, no Perseid but probably a late Delta-Aquariid) crossing Andromeda Galaxy and with multiple outbursts.
Technique: parallel exposure with two imaging systems:
(1) Canon 200mm/F1.8 (open), SX-36, L-pro filter, 240 sec exposure time,
(2) Canon 200mm/F1.8 (open), Sony A7s (CentralDS modded), ISO 3200, IDAS-V4 filter, 90 sec
both on EQ8 mount unguided.
Final image processed with 32 subframes from each system for the galaxy and the stars resulting in a L-RGB image.

Thanks to everyone who took the time to view, comment, and fave my photo. It’s really appreciated. 😊
Comet 45P, at last there were some subframes usables, with individual background extraction, so that I could integrate some of them. Now the split tail is well visible.
Parallel exposure on ASA DDM 85 mount:
(1) 7 x 60 sec Hyperstar C14/F1.9, Lumicon comet filter, ASI 1600 mono, cooled (-32° C), processed as emerald green in the RGB image.
(2) 7 x 60 sec RASA 11"/F2.2, L-filter, ATIK 490 color, cooled (-18° C)
FOV 1° x 0,9°, location: Tenerife 1180 m altitude. 19:20 h - 19:50 h UT (with many missing subframes due to clouds)
I revisited a bunch of previous RGB data and now added about an hour of Hα data. This galaxy really needs it. All those pink areas are regions of intense star formation, where some of the most massive stars are being born. The particularly big pink blob in the upper right is known as NGC 604. It is an emission nebula in another galaxy that is so large and bright that it gets its own designation. Think of really outstanding examples like this in our own sky -- M17 or the Eta Carina Nebula. This one has both of them beat for size and luminance. It only looks small because it is 3 million light years away.
All subframes shot with a Celestron Edge HD 925 at f/2.3 with Hyperstar. RGB data taken over multiple nights with an Atik 314L+ color CCD; hydrogen-alpha data taken with an Atik 414-EX with Atik 7 nm bandpass filter. Preprocessing of images in Nebulosity; registration, channel combination, and processing in PixInsight; final touches in Photoshop.
NGC2070
I used remote observatory, iTelescope, to took this image.
The plan started at the beginning of September 2019. I acquired L, R, G, B, SII, H-alpha, OIII each 300s*1. I did LRGB, SHO, HOO color mapping, and I found out that the luminous frame is bright (or less noise), but the nebulosity is not as sharp as narrowband frames. Since the SII frame is much dimmer than others, I experimentally took single 900s SII subframe. The Hubble Palette image with S:H:O=9:3:3 still shows water blue color (bule+green) in nebulosity and, badly, very red color in star. I did some google search, notice that there might be not so many SII emission at this place. "Ok, I need to change the strategy." I talked to myself at that time.
After that, I focus on HOO composition. I took an extra nine subframes each with H-alpha and OIII filter. Finally, HOO color nebula combines with LRGB stars makes this image more nature.
The plan will be continuous...

I've heard of the Pacman Nebula for a long time and it's not too hard to see the shape that earned its name. I've always zoomed in trying to catch as much detail in the nebula as possible. But this time I zoomed out and notice that there was more to the Pacman identity than just the shape. Viewed from the right angle it appeaAptera that the nebula is rushing ahead to gobble up ⍺Cas. Video game at an astronomical level!
Seestar S50 - 828 ten-second subframes | Polar alignment | Mosaic mode.
This is the first time I've attempted to image the Lagoon nebula, which from my location doesn't rise higher than 14 degrees above the horizon while visible from my garden observatory.
It was only after some recent adjustments that allow my south wall to go a little lower when open that I have been able to get one of my telescopes completely covering the target area long enough to image it.
It is a stack of nine seven-minute subframes through a Hydrogen Alpha filter, total image time 63 minutes.

Description:
This large hydrogen gas nebula lies about 6,000 light-years away in the constellation Cassiopeia, and in the Perseus Arm of our Milky Way galaxy. The nebula is energized by hot stars near the centre in this view, some of which are about 50 times the mass of our own Sun. The nebula has a diameter of about 200 light years.

A one owner from new car up until very recent.
Now at 36.5k, this Uno covered only a few hundred miles every year. A clean MoT history bar corroded subframes on both sides in 2013, to which it received the necessary welding.
This is two simultaneously taken views of the region around the Great Orion nebula, M42. On the left a luminance only view taken through my 80mm triplet APO refractor with a ZWO ASI174MM mono CMOS camera, to the upper left the Running Man nebula can be clearly seen.
On the right, through my 130mm triplet APO (the 80mm sits on top of it) usng an Atik460EX mono CCD and three narrowband filters, Hydrogen Alpha, Hydrogen Beta and Oxygen III to create a RGB image. The H Beta filter proved very useful for picking up the whispier parts of the nebulosity. M43 is the small bright nebula towards the top of this image. I was careful to keep individual subframe exposures short enough to stack without the bright part of the M42 nebula obscuring the Trapezium.

"The Pleiades also known as Seven Sisters and Messier 45 (M45), is an asterism of an open star cluster containing young B-type stars in the northwest of the constellation Taurus. At a distance of about 444 light-years, it is among the nearest star clusters to Earth and the nearest Messier object to Earth, being the most obvious star cluster to the naked eye in the night sky. ... The cluster is dominated by hot blue luminous stars that have formed within the last 100 million years." en.wikipedia.org/wiki/Pleiades

Let me know what you think!
The famous Spaghetti nebula, more properly known as Simeis 147, on the border of Auriga with Taurus is a supernova remnant of a star which exploded around 40,000 years ago. It is a large object, spanning more than 3 degrees, but also very dim. This image is a 6 panel mosaic with each panel being a stack of 300 second subframes integrating to 10 or more hours total exposure. The imaging camera was a QHY168C with an STC duo-narrowband filter. The scope was a WO Zenithstar 102. Sequence Generator Pro was used to plan the mosaic and manage the image capture. Guiding was via PHD2. The mount was a Skywatcher EQ6R Pro. All post-processing was carried out in PixInsight.

Special:
- "What Chevrolet can do, we can too," Pontiac thought, when Chevrolet released their Camaro, designed by Pontiac Motor Division General Manager John DeLorean.
- They (heavily) shared the same coach work (the F-body platform), but with detailed changes, such as grille (twin grilles of a bumper-integral design), chrome trim strips, three vertical air slots on the front edge of the rear body panels and vent windows in the front.
- Unfortunately the Camaro outsold the Firebird two to one in the beginning.
- The Camaro and the Firebird were at the forefront of America's muscle car generation.
- A Firebird was the 1967 Pace Car of the Daytona International Speedway.
- In the period that Pontiac released the Firebird, the demand for convertibles dropped, like the Mustangs and the Camaros. The average American would rather buy a draft-free coupe with air conditioning.
- This first generation Firebird Series 22400 (1967-1969), with its characteristic Coke bottle styling, was available as this 2-door Sport Coupé and as 22467 2-door Convertible (15,528 units built).
- The were assembled in Lordstown (Ohio), Norwood (Ohio: from 1969 on) and in Van Nuys (California).
