早兩天難得半晚天清，來試試每年秋季也要拍一下的M31。 M31（仙女座星系 Andromeda Galaxy） 是我們的一個鄰居星系，距離我們約250萬光年，大小約是銀河系的兩倍。因相信跟我們銀河系很相似，而常常被作為研究比較之用。
曝光訊號不太夠細節有點粗，留待日後好天再增加一點曝光時間吧！

Hi Folks,
Once again, the weather has stopped me from collecting new data, so I have done another Reprocessing Project!
This time, I went back two years to 8.3 hours of narrowband data I had collected for SH2-132 - better known as the Lion Nebula!
This is an impressive region of emission and dark nebulae and star clusters measuring more than one degree across. This is located 10,00 light-years away in the constellation of Cepheus.
The original image looks a little crude to me today, and I am much happier with my new version. It's fascinating what can be done with old data when leveraging new tools and techniques - along with some more experience under my belt.
Both the old and the new versions can be seen below.
You can see the original Project Post for this here:

A detailed processing walkthrough of the new version can be seen here:

Hope you like the new version!
Clear Skies,
Pat

This is a 134 shot panorama of the Milky Way setting above The Pinnacles Desert, 2 hours north of Perth in Western Australia.
This was taken just at the end of astronomical twilight so you can clearly see the Zodiacal Light just left of centre. Just above the horizon on the left is the Carina Nebula and on the opposite side of the image is the North America Nebula.

Probably one of the more famous deepsky objects that almost everyone easily recognizes, The Horsehead Nebula in the constellation Orion. This is a work in progress and consists of 29 x 1 minute exposures at ISO 3200 using a Canon 6D and Canon 400mm lens. The brightest star in this image is also the left-most star in Orion's Belt (named Alnitak). Photo taken last evening (December 25, 2014).

I love this shot because it shows the unique diversity of the cosmos in one frame. The emission nebula (sh2-101) at the lower right is an H II region emission nebula in the constellation Cygnus. It is sometimes called the Tulip Nebula because it appears to resemble the outline of a tulip in photographic images. It lies at a distance of about 6,000 light-years from Earth.
The blue ring nebula WR 134 at the upper left is a Wolf-Rayet variable star also located about 6,000 light-years from Earth in the constellation Cygnus and is surrounded by a faint bubble nebula created by the star's intense radiation and fast winds. It has five times the radius of the sun, but is 400,000 times brighter than the sun due to a temperature of over 63,000 K.
This is a result from a total exposure time of more than 9 hours: 600 seconds for OIII, and 450 seconds for Hα and SII, a total time of nearby 9 hours, captured in my Garden Observatory in the Alps in Pongau in Salzburg/Austria with the QHY268M and a 420mm f/2.8 Newton. I developed it with Astro Pixel Processor, Pixinsight and Adobe Photoshop.

The deep southern Milky Way arching across the sky, from Puppis and Vela at upper right, to Centaurus at lower left. The two Magellanic Clouds are at lower centre, with the Large Cloud at top. The Small Cloud is just setting above the treetops with the globular cluster 47 Tucanae visible as a star below the Cloud amid the trees.
The Carina Nebula and Southern Cross are at upper left, and the paired stars of Alpha and Beta Centauri are rising above the trees at left. Canopus is at right, while Sirius shines through the gum tree at upper right. The faint red arc of the Gum Nebula in Vela can be seen at top in the Milky Way.
The scene depicts the austral autumn evening sky of late March from a latitude iof 30 degrees south.
This is a stack of 5 x 1.5-minute exposures, all tracked on the iOptron Sky Tracker, at f/2.8 with the 15mm fish-eye lens, and Canon 5D MkII at ISO 3200. The ground comes from just one of the tracked exposures to minimize blurring. Taken from the Tibuc Gardens Cottage near Coonabarabran, NSW, Australia on March 30, 2016.

This is a 57 shot panorama of the Crux & Carina region of the Milky Way above the sand dune desert of Nambung National Park, two hours north of Perth in Western Australia.
Crux is the dark nebula almost in the direct centre of the image while a little further above is the pink coloured Carina Nebula. Near the top is the deep red coloured Gum Nebula, captured thanks to a Nantong Foric screw on h-alpha filter. To the far left, just above the horizon, is a red noctilucent cloud.
The Eastern Veil Nebula is a part of the much larger Veil Nebula, a supernova remnant of a star 20 times the size of the Sun. It exploded 8000yrs ago and this cloud of ionized gas has been expanding ever since.
This image acquired through Ha (red) and OIII (blue) filters over a total integration time of 5.6hrs.

Stargazing with my family is always a fun experience, and during our recent Namibia vacation, I had the great pleasure of introducing them to the wonders of the southern hemisphere sky.
Northern hemisphere dwellers are probably familiar with the constellations and nebulae in the upper part of the image, including the famous Dark Horse and Rho Ophichui. The Lobster, Cat's Paw, and Prawn Nebulae may also still be known to those not living too far north.
The next bright red hydrogen emission nebula, however, was a new one for me. NGC6188. Even though it was discovered by John Herschel in 1836, it never rises above the horizon in my home country, Switzerland.
Following the dust lanes of the Milky Way band further south, leads to the bright stars Rigil and Hadar (Alpha and Beta Centauri) and eventually to a very dark and dusty area, called the Coalsack.
To the lower right of the Coalsack lies the famous constellation Crux, the Southern Cross. South of the Southern Cross are two more prominent red nebulae, IC 2948, the 'Running Chicken Neblua', and NGC 3372, the bright 'Eta Carinae Nebula', one of the largest diffuse nebulae in our skies. Although it is four times as large as and even brighter than the famous Orion Nebula, the Carina Nebula is much less well known due to its location in the southern sky.
I conclude this little tour with the open star cluster IC 2602, the 'Southern Pleiades' near on the upper left edge of the Eta Carinae Nebula.

This was a misty, awe-inspiring night at Spruce Knob Lake while the AT111 and Nikon D5300 captured data on the Leo Triplet of Galaxies. Jupiter taking center stage while following closely behind Antares and Rho Ophiuchi.
Even after growing up in SW Colorado, I believe the clarity and visibility of the Milky Way that was offered later that night was the best I've ever seen with the naked eye. Taken on Monday, June 3rd / morning hours of Tuesday June 4th, 2019 in West Virginia.

M101, a face-on grand spiral galaxy, 23 million light-years away. Nikon D850, 200-500 f/5.6 lens, 500mm, 11 frames each 90 sec., f/7.1, ISO 5000. Post-processed in Lightroom and combinded in Starry Sky Stacker.
My first deep sky mosaic made up of 3 panels joined to create a single image covering an area of the night sky nearly 15 degrees wide by 10 degrees high.
Objects visible include the Southern Cross (Crux) which should be recognisable by anyone in the Southern Hemisphere. NGC4755, the Jewel Box, is a cluster of bright stars just to the left of the left star in the cross. In the bottom right of the image the red cloud is hydrogen gas in IC2944 also known as the Running Chicken Nebula. Directly above this the bright cluster of stars is NGC3766, the Pearl Cluster.
The Jewel Box and Pearl Clusters were identified in 1752 by French astronomer Nicholas Louis de Lacaille who travelled to South Africa to catalogue the Southern night sky during 1751 and 1752. The Running Chicken Nebula (IC 2944) was first catalogued in 1834 by Englishman John Herschel during a four year trip to South Africa made to catalogue and describe over 1700 night sky objects using a large reflector telescope with a 20 foot (roughly 6 metre) focal length.
This image was taken on 21 February 2025 from Bortle 2 skies in Coalgate in Canterbury, New Zealand, using a Samyang 135mm lens, ASI2600MC camera and CEM40 mount without guiding. Each of the 3 panels were 84 images of 30 seconds stacked in DSS, then GraXpert, combined in PS, and final edit in Siril. The second image was named using the nova.astrometry.net site.
Thank you for choosing this image of the Southern night sky for Explore on March 5, 2025.
There's a bright-ish comet passing through Orion these days [C/2020 M3 (ATLAS)]. It's the green fuzz at the top of the first photo, above Orion's three belt stars along with the decidedly bright Orion Nebula at lower right and nearby Horsehead and Flame nebulae around the. bottom belt star. The other image shows a detail of the comet with a longer focal length; no tail showing but a nice big coma. By the way the green is from carbon molecules excited by sunlight to emit mostly green light.

Taken at Table Mountain in WA state. Equipment: Tele Vue 76mm refractor, Modified Canon XSi (450D) DSLR, iOptron iEQ45 Pro Mount. Total integration time: 80 minutes (16 x 5 mins).
I was hoping to shoot Comet 12P/Pons-Brooks before it fell below the horizon, but I was overly optimistic. By the time I arrived at my imaging site, the comet was sitting on the western horizon. I had all my gear and nearly clear skies and hadn't imaged in well over a year, so rather than head home, I decided to image something. I chose the Pinwheel Galaxy on a whim. I was able to squeeze the Whirlpool Galaxy into the frame as well.
Instead of using Astro Pixel Processor for gradient removal (my license expired), I used GraXpert for the first time. It worked well, especially considering the cost (free!).

This is a 10 shot panorama of the Carina Nebula (top right corner) and the Large & Small Magellanic Clouds (centre) above Lake Ninan, 2 hours north east of Perth in Western Australia. The light pollution on the right is from the nearby Wheatbelt town of Calingiri.
- www.kevin-palmer.com - Jupiter is currently the brightest object in the sky aside from the moon. It reaches opposition on June 10th. Right now it's moving through Sagittarius in front of the milky way. I put my camera on a tracking mount to capture more detail in the surrounding sky.
