Ermita de Sta María de Melque
This small church is located in a zone relatively isolated from Madrid. I find it an interesting location for night photography because light pollution is not very high. The only negative I find about this place, IMHO, is the fence around the church, as it affects the charm of the place a little.
This is my first serious attempt at long exposures of the sky with a star tracker (Skywatcher star adventurer). The sky is a stack from 11 exposures of 60 seconds at ISO 800, stacked with DeepSkyStacker.
The foreground was shot with a Nikon D850 and Samyang 24 1.4 at F2- 20 seconds at ISO 4000
... I actually went out Aurora hunting on the night of this image but there was nothing happening so I turned around and captured this instead
Low over the trees on the valley side.
11 x 1-min exposures at f/4 and ISO 3200. Astro-modified Canon EOS 600D and Leica Summicron 50mm f/2 lens on a Vixen Polarie star tracker.
Frames stacked in DeepSkyStacker software; curves and colour balance adjusted in Canon Photo Professional; noise reduced using Cyberlink PhotoDirector.
After my first test shot with little exposure time under rather unfavourable conditions already hinted at the famous Horsehead nebula, I tried this again, this time for real. A wonderfully clear night, no moon, and only one target...
I was able to acquire 2 h 8 min in 256 useful subs before my camera's batteries ran out and I got cold...
But I was amply rewarded! This image taken at 300 mm focal length with the TAIR-3S just exactly fits all the famous objects, from the Flame nebula (bottom left) to Orion's bright belt star Alnitak, and of course the Horsehead nebula, to the Running Man nebula and the Great Orion nebula M42 on the top right. I also like the soft but numerous spikes from the slightly stopped-down lens on the brighter stars.
Maybe I'll find some time to compose a HDR image some time, where the core of M42 isn't burnt out and the Trapezium stars are visible, but seeing has to be quite good for this and M42 season is nearing its end here...
EXIF:
Lens: TAIR-3S (300 mm f/4.5) @ f/5.6
Camera: Samsung NX30, mirrorless APS-C, unmodified
Acquisition: 256x 30 s @ISO3200; total 2 h 8 min

2x2 binning was performed during processing, and a pseudo-luminance channel was created by summing up all three colour channels.
M33 Triangulum galaxy
I've always struggled with this target. I use an old Canon 1100D unmodified camera and really struggle to get the fainter parts of the spiral arms.
This image was done with a Skywatcher 8" quattro with f4 aplanatic coma corrector on a HEQ5 pro mount.
Guiding was with an Altair 50mm guide scope and an Altair GPcam1 AR0130c
I used an unmodded Canon 1100D with an Astronomik clip in ccd filter and a Neewer intervalometer.
Software used was DeepSkyStacker, StarTools & Gimp.

Memories:Noticed this chance alignment was available whilst already capturing a narrowband imaging run on the Fish Head nebula. With no RGB filters in my filter wheel decided to try and capture a bonus greyscale image of the comet via CLS-CCD at the end of my run.
Taken in, and around, Algonquin Park, ON. My first attempt at stacking pictures seemed to work out favorably :) I forgot to take the dark and bias frames when I was there, so I stuck my camera in the fridge to bring the temperature down.
7 shots at ISO3200, f/3.5, 10mm, 30" stacked in DeepSkyStacker with dark and bias frames subtracted.
The strange orange/blue/green glow is actually the Zodiacal light on the horizon - very hard to see typically!!
Inspired by Erik's recent image, and being bored after being clouded out for what seems like decades, I thought I'd faff about :)
A starless version of my recent collaboration with Dave Williams. I've left IC 431 and 434 in there because they are nebulae after all. I've also left in Alnitak and his buddy as I'm not good enough to take them out :)
I won't submit this to astrometry, as it may struggle :)
Here is a triplet of galaxies often referred to as the Draco Trio, NGC 5985, NGC 5982 and NGC 5981. The grouping includes the edge-on barred spiral galaxy, NGC 5981, on the right. The elliptical galaxy NGC 5982 in the center. The last, NGC 5985 is a beautiful face on barred spiral galaxy, on the left. These galaxies are about 100 million light years away. Tech Specs: This image is composed of 60 x 15 second images at ISO 3200 with additional dark and bias frames. Equipment included a Meade LX90 12” telescope, Antares Focal Reducer, and Canon 6D camera. Imaging was done on September 1, 2016.
This is my second attempt at a guided shot of the Pleiades. I doubled the exposure time and took bias frames for the first time.
Taken with a TMB92L, Canon T3i DSLR, Orion SSAG autoguider and 50mm guidescope, and Celestron AVX mount. Consists of 42 240-second light frames and 30 240-second dark frames, all at ISO 800, as well as 15 flat and 30 bias frames. Captured with BackyardEOS, stacked in DeepSkyStacker, and processed in Photoshop.
My humble attempt at capturing our neighbour galaxy Andromeda, using a Canon 200D and a cheap Canon 55-250mm zoomlens. :)
Sadly, I live in a Bortle 7/8 scale. :(
I don't use any filters, so I did lose some quality and detail...
I added Vibrance and Saturation to get the colors.

I used PHD2 for Guiding en Polar Alignment.
I stacked about an hour worth of data in DeepSkyStacker and edited the TIFF in Photoshop 2020 and Adobe Camera RAW. :) (y)
This is NGC 7380 The Wizard Nebula in Cepheus, and I imaged this on Christmas Eve and Christmas Day as it was clear and I'm a sad bugger. :)
Quite small for my setup, and very difficult to process, this is 67 x 300 second subs for just over 5 and a half hours. Looks much better in the Hubble Palette, but I can't do that! :)
Happy New Year guys :)
First night with my new mount (HEQ5) and it was almost perfect clear sky with no moon!
Also it's the first time I've managed to make the guiding work properly, made all the lights 300sec long and only rejected the ones with clouds :D
As you can see, I'm really rusted with processing the images. It's the 3rd image I've processed since February! Noise got out of control, colors could take a better aproach, not happy with the stars....so many things poorly done but I know I will process it again at some point.

This is a planetary nebula in the constellation of Lyra. Planetary nebula are so named because, they are small, round and look like planets.
A planetary nebula is a star entering the final phases of it's life cycle. The more massive stars go out in spectacular style as a supernova. The smaller stars, like that of our Sun. Enter their penultimate phase, that of a white dwarf star, with a little less pazzazz. Though they are no less beautiful.
Captured on 23rd of April from Rochdale, UK.

Canon 450D astro modded with Astronomik CLS CCD EOS APS-C clip filter. Intervalometer used to control the exposures.
6 exposures of 6 minutes each at ISO 400.
Stacked in DeepSkyStacker with darks, flats, dark flats & bias frames. All processing done with StarTools.
Total exposure of 2 hours 24 minutes, including 23 x 2-minute, ISO 3200 frames, taken 24 March 2020 (the other frames were from 2 sessions in 2017 and 2015).
I've had to crop the image more than I'd like because the camera orientation happened to be very different over the 3 the sessions, so the edges were very uneven.
Modified EOS 600D & Revelation 12" Newtonian f/4 reflector telescope.
Frames registered and stacked in DeepSkyStacker software; curves adjusted in Canon Photo Professional; noise reduction in CyberLink PhotoDirector.
Captured the milky way in a very clear summer night whilst sitting on my balcony!
This image consists of 5 single images (and some darkframes) which have been stacked together in post procession.
The bright light pollution in the bottom of the image is coming from freiburg/fribourg.
An unguided image of the Leo Triplet Galaxies (M65, M66, and NGC3628) taken with a Canon 400mm f/5.6 L lens on a ZWOASI183 MC Pro camera. The final image was created from 50 30 second images combined together with Deepskystacker and enhanced with Gimp and Adobe Lightroom.
The Hyades star cluster is the head of the bull in the Taurus constellation; Aldebaran, the brightest yellow star, is the eye. Quite a few dark nebulae are also present in this extent, as well as star cluster NGC 1647 in the upper left.
I normally wouldn't have astrophotographed on a night forecast to have only a small window of clear skies, but it had been a couple months since I had been able to image, so I went for it. I only managed 20 minutes of data without high, thin cloud cover despite shooting for well over an hour, but you have to take what you can get during winter in north Idaho. I'm going to shoot this one again sometime.
Fujifilm X-T10, Samyang 135mm f/2.0 ED UMC @ f2.0, ISO 1600, 20 x 60 sec, tracking with iOptron SkyTracker Pro, stacking with DeepSkyStacker, editing with Astro Pixel Processor and GIMP, taken on Jan. 21, 2020 under Bortle 3 skies.
We had another good astronomy session at Wivenhoe Hill west of Brisbane last night. I spent most of the time doing visual observing with my brother-in-law's 14" Dobsonian telescope, but I also had time for a couple of Milky Way panoramas.
This one is a panorama of the central section of the Milky Way galaxy, taken with a 35mm lens and the Star Adventurer Mini tracking mount. Each panel consisted of 5 x 120 second exposures at f/3.5 and 1600 iso, stacked using DeepSkyStacker. Panorama stitching was done using Microsoft ICE.
Hi all,
This is my longest astrophotography project to date.
The Veil Nebula is a cloud of heated and ionized gas and dust in the constellation Cygnus.
It constitutes the visible portions of the Cygnus Loop, a many portions of which have acquired their own individual names and catalogue identifiers. The source supernova was a star 20 times more massive than the Sun, which exploded around 8,000 years ago. The remnants have since expanded to cover an area of the sky roughly 3 degrees in diameter (about 6 times the diameter, or 36 times the area, of the full Moon). The distance to the nebula is not precisely known, but Far Ultraviolet Spectroscopic Explorer (FUSE) data supports a distance of about 1,470 light years.

Now this is a bit of a hotchpotch of data: Some very old data from the D70 back in the day (for the core), some data from the Canon/ED80/EQ5 and some recent data from the new setup. And some Ha data from my buddy Dave Williams for the outer faint bits.
All thrown into the pot and shaken (not stirred) until, as if by magic, this came out the other end. Good fun....:)

Some of the faint outer region of the galaxy, better visible in much deeper exposures, is just visible to the right.
A mixture of old and new data: 19 x 4-minute manually-guided exposures at ISO 1600 (taken 18 April 2018 and 28 December 2014) and 31 x 1-minute unguided exposures at ISO 6400 (taken 18 Mar 2021). Modified EOS 600D & Revelation 12" f/4 Newtonian reflector telescope.
Frames registered and stacked in DeepSkyStacker software; curves adjusted in Canon Photo Professional; noise reduction in CyberLink PhotoDirector.
These "clouds" are a star-forming region referred to as the Bubble Nebula, or NGC 7635. In the middle of this cloud, there's a hot young star creating some significant solar wind that is blowing out a spherical section, leaving behind something that looks a bit like a bubble. The whole formation is a little over 7,000 light-years away in the direction of Cassiopeia.
I often use narrowband imaging for my astrophotography, but I shot this one in pure RGB, so this is exactly what both the eye would see if it could gather in enough light. And this is exactly what a normal full-color camera would show if I did a similar exposure with it. BUT... I only have a monochromatic astrophotography camera, so this came from separate exposures in red, green, and blue.

This is a stack of 9 exposures, i.e. 15 minutes in total plus 13 dark-frames. The camera (Sony ILCE7) and the 200mm lens (Canon EF 70-200mm 1:4L) have been attached to a "Star Adventurer"-mount in order to compensate for earth rotation, while shooting at F4.0/ISO 1600. Stacking has been done with DeepSkyStacker, and final editing with Photoshop CC 2015.5. Place of observation was close to Bremen, in the northern part of Germany.
30 one minute exposures, ISO 800.
Must try this again when there is no moonlight.

C/2022 E3 (ZTF) is a long period comet from the Oort cloud that was discovered by the Zwicky Transient Facility on 2 March 2022. The comet has a bright green glow due to the presence of diatomic carbon and cyanogen.
The comet reached its perihelion on 12 January 2023, at a distance of 1.11 AU, and the closest approach to Earth was on 1 February 2023, at a distance of 0.28.

أقرب وصف قد يتراءي إلى ذهني عن السديم هو أنه حضانة للنجوم حيث أنه موضع ميلاد الكثير منها كونه عبارة عن مزيج من غازات الهيدروجين و الهيليوم و غبار كوني. و كل ما يحتاجه النجم كي يولد هو انصهار نووي. كذا الحال في سديم الجبار (M42) حيث تولد فيه النجوم إلى يومنا هذا. و يبعد هذا السديم عنا حوالي ١٣٥٠ سنة ضوئية (كل سنة ضوئية تعادل قرابة ١٠ تريليون كيلو متر). و تنقسم السُدم عامة إلى نوعان: سُدم إشعاعية و اللتي تشع من ذاتها نتيجة تولد طاقة عند تكون الهيدروجين و سُدم عاكسة و اللتي تعكس ضوء النجوم المجاورة.
بإمكانكم رؤية سديم الجبار بشكل واضح و بالعين المجردة و لكن قد يغلب على الظن كونه نجما آخرا.
A closest description that comes to my mind about Nebulas is to think of them as the birthplace of stars. Literally thousands of stars are being formed in nebulas till this day and all it needs is a little process called fusion of Hydrogen to form the core. The great Orion’s nebula (or M42) is one of the closest to us. When i say close, i mean 1350 light years away (1 light year is 10 Trillion Kilometers( yet on a dark night you can clearly see it with your naked eye, except that you have to know that it is a Nebula and not another star. Nebula’s can be mainly categorized to two types: Emission Nebulas, the one that emit light due to formation of Hydrogen that gives out energy in the form of red light and reflection nebulas that (as the name implies) reflect light from other nearby stars.

First astro session of 2021, and a fairly predictable subject at this time of year! Having said that, I've not imaged M42 with the 12" Newtonian 'scope for several years.
I didn't take many sub-exposures, but instead a small number each at settings between 5-seconds and 2-minutes, ISO 3200, to preserve detail in the bright inner and faint outer regions of the nebula. I stacked each set in DeepSkyStacker software and then combined them as layers.
Additional post-processing: minor curves adjustment in Canon Photo Professional; noise reduction and colour gradient correction in CyberLink PhotoDirector.

I’ll be honest, I really never viewed Polaris under any magnification before. I’ve always used it as a guidepost to align a telescope or other piece of astronomical equipment. While recently setting up my pier and Meade telescope for the first trial runs, I focused the scope on Polaris to begin alignment, and snapped a few quick pictures. That is when I noticed a little companion star right next to it! Low and behold, Polaris is a multiple star system with an 8.7 magnitude companion (see image in the two o’clock position). Polaris actually has another, closer star, designated Polaris Ab that amatuer scopes can’t resolve. You can see a Hubble view of this star at:

This is the Triangulum Galaxy, also referred to as M33. At a distance of over 2.5 million light-years away, it is a bit further out than Andromeda Galaxy, but it is still one of our closest galactic neighbors. There are around 40-billion stars in this spiral galaxy.
I shot this image a few nights ago using about 5 hours of RGB data. I was individually shooting 3-minute exposures in each color, then combining those images to get what you see, here.
