This is a 12 stack image of the Milky Way core taken at Yenyening Lakes, about 2 hours east of Perth in Western Australia. It was stacked using a free program called Sequator.
This was the first time I've captured a completely clear sky above Knowlton Church in north Dorset. Having bumped into a pair of deep sky astrophotographers just packing up when I arrived, I had the place to myself, and established a close enough alignment with Polaris to work with 4-minute sky exposures. The core of the Milky Way no longer appears above the horizon this late in the year, but I'm encouraged with the improvements in my equatorial mount alignment and sure that I'll get to work with even longer exposures early next year.
IC 2177 - better known as The Seagull Nebula - is an emission nebula located about 3,650 light-years away, situated at the borders of the constellations of Monoceros and Canis Major.
This is my second image of 2022, and is the result of only 2 hours and 10 minutes of Narrowband data collected on nights of March 9 and March 29, 2022. My first image, of Thor's Helmet, was taken at the same time and suffered from the same weather and access to the sky issues that caused it to have a low integration time as well.
This image was shot with my Askar FRA400 F/5.5 Telescope Platform with the IOptron CEM28 and the ASI1600MM-Pro Camera with Astronomiks 6mm narrowband fitters.
It would seem that event this year have conspired to produce a couple of images with short integration times. Normally I would shoot for between 9 and 12 hours for such objects. Since this was not possible with these image, I had to up my Pixinsight Processing game to get the best results I could from limited data!
As was the case with my Thor's Helmet image, I was somewhat surprised that the final image came out as well as it did. Don't get me wrong - it is so very far from perfect - but not bad considering the circumstances!

I’ve been trying to experiment on wide field views, at lower ISO, and longer exposures, but the weather has not been cooperating. This is a single 4-minute exposure of Orion, obscured by light cloud cover, I think it was still a nice effect.

My birthday present to myself last year was a night spent with my telescope and a few cold beers. I find it very calming to just sit back and observe the heavens above. What better way to spend a birthday? Maybe this year I'll invite a few friends for a 'star party' instead.

NGC 6888 - The Crescent Nebula - is an emission nebula located 5000 light-years away in the constellation of Cygnus.
This image was taken on my Astro-Physics 130mm EDT f.8.35 APO telescope platform, which uses a ZWO ASI2600MM-Pro camera, and is supported by an IOptron CEM60 Mount.
12.9 hours of narrowband and RGB broadband data were collected for four nights ending on September 2nd.
This imaging project finishes up with the data collected on our last imaging cycle - let's hope the next one has good weather so I can collect some new data to work on!
The image was processed by using a Synthetic computed Luminance image and extensive use of starless processing workflows. The final image is a BI-COLOR Ha/O3 image with RGB Stars.

This video is a kind of experiment. While I cover the image processing done for an image in great detail in the web post, sometimes it may not be evident what the strategy is - and you may lose the forest for the trees.

- www.kevin-palmer.com - At the end of October I went camping at Lily Lake, at 6,000 feet in the Bitterroot Mountains of Idaho. It was there I saw one of the darkest and clearest night skies I've ever seen. It was very cold, but I had a warm fire and a great night of astrophotography. In this shot I was testing out the half speed setting on my new iOptron Skytracker. It let me take a 66 second shot with minimal blurring on the trees and stars. It was one of the last opportunities to shoot the summer milky way until March. As you can see the center of the galaxy was already at the horizon as soon as it was dark. It was also the last possible weekend to camp here as a snowstorm came a couple days later and made this site inaccessible until spring.
Here is a photo of Messier 20, the Trifid Nebula I took last year. You can also see M21 to the right.
I can't get natural colors and faint details like this from home!
This was photographed under the pristine dark skies of the Cherry Springs Star Party in Pennsylvania, USA.
I realize the stars are a little wonky, and I believe it's the lack of a dedicated flattener for this scope, and possibly the cheap UV/IR cut filter used!
I guess I'll just have to try it again :)

De SkySafari Plus y hubblesite.org: la nebulosa “burbuja” fue descubierta en 1787 por el astrónomo Británico William Hershell está a unos 11.000 años luz y del sistema solar y fue creada por un fuerte viento estelar de la estrella central masiva y joven (unas 45 masas solares) sobre el material denso en la nube molecular circundante. Tiene unos 7 años luz de diámetro.
Por su parte, la nebulosa Sharpless 2-157 (Sh2-157) es una nebulosa brillante a 43.000 años luz del sistema solar. Quiere decir que es unos 32.000 años luz más distante que la “burbuja”.
En la imagen además se ven también las nebulosas Sh2-158, Sh2-159, Sh2-161 y el cúmulo de estrellas NGC7510 que tiene unos 20 años luz de diámetro.

All my previous photos with the Milky Way have been done from a static tripod, and I used (relatively) short exposure times in order to freeze it above the landscape. However, I recently purchased an iOptron SkyTracker Pro, which pans the camera with the sky's movement. It enables much longer exposures before the stars start to blur.
This image is an average of 12 30-second, f/2.8, ISO 4000 images taken with the Rokinon 50mm f/1.4. It reveals quite a bit more structure in the Milky Way than my typical shots. It was taken from the dark, clear skies of Mauna Kea. If only my camera was modified for H-Alpha sensitivity...
What does this image show? The dark band is dust which blocks light coming from the glowing gas and dust toward the center of the milky way. Our galaxy is a disk with a central bulge, and we are located 25,000 light years from the center. The density of stars and gas and dust increases toward the center of the milky way, but (at least at optical wavelengths), we can't actually see to the center due to all the dust in the way. However, if we observe at infrared or longer wavelengths, it's possible to see through the dust and map the galaxy.

This is the byproduct of some testing I did this morning on my iOptron SkyTracker which I've had collecting dust for a year or so now. The image was taken at Sullivan's Rock, just outside the Perth city limits and features the Carina Nebula (the pink splotch) and the Large Magellanic Cloud, just left of the red airglow on the bottom right. I intended doing a full panorama but ran out of time while also learning that a tracker will mess with your grid pattern while taking panoramas :) A valuable lesson for next time....

NGC 3628, also known as the Hamburger Galaxy is an unbarred spiral galaxy about 35 million light-years away in the constellation Leo. It was discovered by William Herschel in 1784. It has an approximately 300,000 light-years long tidal tail. Its most conspicuous feature is the broad and obscuring band of dust located along the outer edge of its spiral arms, effectively transecting the galaxy to the view from Earth.

Caroline's Rose - also know as The White Rose - is one of the oldest open clusters know. It's located in a rich star field, close to the galactic plane, in the constellation Cassiopeia. This large cluster was discovered by Caroline Herschel (1783) and is an obvious omission from the Messier catalogue. The cluster contains more the 150 stars and is estimated to be 8k light years away. At this distance, its diameter is about 60 light years.
This beautiful cluster is located in a rich Milky Way star field and looks great in modest telescopes, and is easily seen with binoculars.

This is the Cigar Galaxy, otherwise known as NGC 3034 or M82. This galaxy is ‘nearby” it’s at a neighbourly distance of 12-million light-years, in the constellation of Ursa Major. The galaxy itself is classified as a starburst galaxy. As a whole, M82 is 5 times brighter than the Milky Way. Up until recently, M82 was thought to be an irregular galaxy, but astronomers have since discovered two spiral arms.

This is a 47 image panorama of the core of the Milky Way as it was almost directly overhead about 10km outside of Dowerin in Western Australia, 2 hours east of the state's capital city of Perth. With much less atmosphere for the light to pass through, viewing the core is about as good as it gets when it's directly overhead and the same can be said for photographing it.
I was initially hoping to do a full panorama of the core setting in the west at a nearby lake but access to the area wasn't possible as it was totally fenced off. So I had to make do with testing out my new 85mm lens. This is easily the most detailed image I have captured of the core, a reasonably small field of view but it still required 47 shots with the longer lens. I can't imagine how many shots I will need for a full pano!

This is a 57 shot panorama of the Milky Way rising over Elephant Rocks, a granite outcrop resembling a herd of elephants, near Greens Pool 15km west of Denmark in Western Australia. Greens Pool is popular for its naturally sheltered swimming areas and its amazing turquoise waters.
This location is about 5 hours south of Perth and has some of the darkest skies I have ever witnessed, absolutely spectacular.
This object sits up in the constellation Cepheus. The squid shaped nebula is extremely faint and was only recently discovered in 2011 by an amateur astronomer.

A close-up of Comet NEOWISE (C/2020 F3) on the night of July 14/15, 2020 with a 135mm telephoto lens, and cropped in somewhat. But the field is about 10° high and the white dust and blue ion tails extend across the frame and beyond it. Some of the banding structure in the dust tail is visible.
VIsually in binoculars the ion tail was barely visible with a little averted imagination (!) but the dust tail easily extended about two binocular fields, so about 12 °.
This is a stack of nine 1-minute exposures with the 135mm Canon lens wide-open at f/2 and Canon EOS Ra camera at ISO 800. The camera was on the iOptron SkyGuider Pro tracker tracking the stars not the comet. Yes, the comet will have moved slightly against the background stars over the few minutes of the capture, but not enough to significantly blur detail at this image scale.
I shot this about 12:45 am on July 15, 2020 from Dinosaur Provincial Park, Alberta, latitude 51° N. The comet head was about 9° above the northern horizon. The Sun was 15° below the horizon, so still not astronomically dark.
The comet was also low in the north and so I have added brightness and color adjustments with gradient masks to even out the background, as the sky was brighter toward the horizon at the bottom, plus the sky also had some faint aurora adding magenta casts toward the bottom. Automatic gradient removal didn’t do a good job in this case. Plus despite being the middle of the night, the sky was still deep blue this low to the north due to perpetual summer twilight. But I’ve retained that sky tint.
Stacked and aligned in Photoshop.
Well, that's a surprise! Sure looks like a bright meteor photobombed my latest image of Comet C/2023 A3 taken through my smaller telescope. At least I'm pretty sure it's a meteor. I thought it could have been a bright satellite glint or aircraft, many of which inhabit a large fraction of my images. But I couldn't find a bright satellite at this location and time in SkySafari, which maintains an accurate list, and It doesn't really look like an aircraft trail, which usually have multiple solid streaks with shorter dashes from the flashing lights.
It appeared in one of 90 60 second frames taken on the evening of November 1st from suburban Bloomington, Indiana. This is a composite of the frames, combined to register on the comet moving against the stars, and again to register on the stars. The single frame with the meteor was added as a separate layer.

In this photo we have the Eclipsed Moon, Antares-Rho Cloud Complex, the Blue Horsehead and some special visitors... Sprites!
This is a composition of two stacks. One stack of 5, 30-seconds, F3.2, 3200-ISO at 85mm for the starfield and one stack of 5, 2-seconds, F3.2, 3200-ISO to expose the Moon properly.
Underneath the frame of view, several Thunderstorms in Central/Eastern Oklahoma were putting on a Lightning show. I was lucky to capture two sets of Sprites in my long exposures and saw a third set of Sprites "naked eye" just out of frame.
I believe being at a Bortle-2 dark sky location made the difference in capturing the rare and faint Sprites.

The region of the Cone Nebula (NGC 2264) in the constellation Monoceros, a large complex of dust and gas forming new stars. At bottom right is another feature, a much smaller cloud of mostly dust (NGC 2261) reflecting light from a star. The star's brightness varies so the reflected light does too. For this reason it's known as Hubble's Variable Nebula, named after Edwin Hubble, the astronomer who discovered it, not the orbiting telescope.
I have been experimenting with a sky guider pro and small scope. I was struggling with tracking and this my exposure times short . i tried autoguiding but the weight of extra kit needed seemed to outweigh any gains . So i went out and bought a William optics wedge and this seems to be a game changer . Finally round stars 60 second exposures and autoguiding working . I was starting to think the focal length (360mm) was to much for the tracker .
