Taken with my ZWO AS120MM-mini guide camera Skywatcher 130PDS and a a x3 barlow. Video recorded in Sharpcap, processed in Autostakkert and sharpened in Registack.
It was my late father who got me into astronomy with the Moon being one of his favourites. I vividly remember his pointing this out when showing me.
I've not really got into closeup Moon photography before so abit of a first for me. My sister and brother came to visit and stayed in their camper van. My brother in law Nick is interested in taking up the hobby at some point so we set up the equipment. When the Moon is so full you have to take pictures of the Moon.
I'm not sure I sold it very well because there was a lot of faffing about. I've not done it for a while, it was cold, I was using my rubbish laptop and the seeing was terrible.
Anyway, we managed to get some pic's and in the end it wasn't too bad.

This ISS solar transit was visible from our garden in Oxfordshire at 14:20:01 BST 15th June 2021.
I captured it from Oxfordshire, UK with a William Optics refractor fitted with a Thousand Oaks glass solar filter. The camera I used was an ASI120MC. The video was captured using SharpCap, then I processed the video using PIPP, extracted frames were processed in Lightroom, stacked in StarStaX then final tweaks in Photoshop CS2.
Today's transit was much easier to capture than yesterday's daytime Moon transit was, but the transit chord was not where the prediction showed, so it just shows that even with the best planning, it's possible than orbital changes to the ISS's orbit can change enough that you could miss the transit entirely. I'm glad I decided to do this without any Barlow lenses in place because if I hadn't had such a large amount of the solar disc in view, I would have missed this! The sunspot you can see on the upper left side is AR12833.
If you want to look for transits from your location, you can use the transit finder website: www.transit-finder.com
PLEASE NEVER ATTEMPT TO OBSREVE OR PHOTOGRAPH A SOLAR TRANSIT WITH A PROPER SOLAR FILTER IN PLACE - IT COULD RESULT IN PERMANENT EYE DAMAGE

A supernova remnant some 5000 light years out in space. As with the Cygnus Loop you can envision the central point where the star must have exploded pushing out the gas and dust; now many thousands of years later some parts of the shell are brighter than others and form this interesting jellyfish shape. Unlike Cygnus/the Veil what we can see here is almost all hydrogen/red. For this version I added two hours of HA narrowband capture, improving the contrast and detail of the nebula.

My major August project! About 5 hours' worth of 7 minute frames captured over three nights. This is also my first attempt at this object. It's quite magnificent - check out all those dust lanes! This version has stars removed to reveal the brilliant nebula.
The Pelican Nebula is an emission nebula located in the constellation Cygnus, which represents the Swan, near the bright star Deneb. The nebula was named for its resemblance to a pelican and is associated with the neighboring North America Nebula (NGC 7000).
The Pelican Nebula is one of several notable nebulae found in the area of the night sky with the Northern Cross. It is located around 1,800 light years away from the Solar System and is an active star forming region with a particularly active mix of star formation and evolving gas clouds.

The nebulae in Auriga have been on my astrophotography bucket list for a while, and finally I had good weather while the constellation was still high enough in the sky. Seeing was also quite good, rewarding me with nicely pinpoint stars.
So I set up the Redcat 71 at the Volkssternwarte München, which neatly frames the Flaming Star nebula IC 405 and Tadpoles nebula IC 410. I let the camera tick away while attending an interesting talk about rocket engines - complete with some noisy, smelly live demonstrations. A great evening!
In the end, I collected almost 3 hours of useful data through the dual band filter between nightfall and the object setting behind nearby buildings. It would even have been about half an hour more if it wasn't for an inconveniently placed crane... Oh well.

Messier 31 The Andromeda Galaxy. Our Closest Galaxy Neighbor. This object never gets old to me. The things it reveals to us are amazing. The small lighter colored area in the left side of the galaxy is NGC 206. It is a star cloud of more than 300 large blue stars. Zooming in to the feature can reveal some of the individual stars. Another M31 image on this page is higher resolution and reveals more of them. M31 has many such intriguing discoveries to explore.
Technical Information: This image was taken from a Bortle 4 site in Landers, CA, USA on a New Moon night. Telescope: Explore Scientific ES80 APO Refractor with a FL 480mm and an Orion .67 Reducer. Guiding was with Orion 50mm Guide Scope FL 242mm with a ZWO ASI290MC for the guide camera. Mount: Celestron Advanced VX. Main imaging camera: ASI294MC PRO cooled to -5C. Exposures: 24 x 120s with Gain at 120. No darks, flats or bias frames. Processed in PixInsight with use of Masked Stretch, Star Masks, Inverted and Non-Inverted Range Masks. Slight crop. Polar alignment was with SharpCap Pro.
This capture shows the lovely nebulae that lie around the left-most star in Orion’s belt. This star, Alnitak, is actually a triple star system and lies about 1260 light years away from us. The Flame Nebula, on the left, lies around 1300 light years away. The Horsehead Nebula, also known as Barnard 33 is around about 1500 light years away and is a part of the Orion Molecular Cloud Complex where star formation is taking place. The blueish nebular cloud almost at center is NGC2023. What must this all look like if we were in orbit around the Alnitak system?
I think this is my best capture and processing of this part of the sky to date. I’m very happy with the clarity, lack of noise, lack of star blooming and color of the final image. Learned a lot about doing a better of job of selecting correct color balance, offset, gain and exposure settings this time around. I also had to remove some satellite trails by learning about and utilizing Kappa Sigma clipping during stacking in DSS, which does nice work. Also learned not to push too hard on the processing side and carefully utilize HDR software to bring out some extra goodness. Sometimes, stepping back, unlearning what you’ve learned and starting from scratch pays off.

Messier 1 Supernova Remnant. The Crab Nebula
The Crab Nebula (catalogue designations M1, NGC 1952, Taurus A) is a supernova remnant in the constellation of Taurus. The common name comes from William Parsons, 3rd Earl of Rosse, who observed the object in 1840 using a 36-inch telescope and produced a drawing that looked somewhat like a crab. Corresponding to a bright supernova recorded by Chinese astronomers in 1054, the nebula was discovered earlier by English astronomer John Bevis in 1731. The nebula was the first astronomical object identified corresponding to a historical supernova explosion.

Messier 45. Old Friend. New Effort. Zenithstar 81
Note: I intentionally did not stretch the image as much as I could because I wanted to contrast the color of the stars in a black background to the blue nebulosity and enhance detail. Also, follow the straight blue swoop in the center-right part of M45 toward the right border of the image ... Zoom in ... Can you find the little, very distant edge-on galaxy?
----------------------------
Messier 45
The Pleiades, also known as the Seven Sisters and Messier 45, are an open star cluster containing middle-aged, hot B-type stars in the north-west of the constellation Taurus. It is among the star clusters nearest to Earth, it is the nearest Messier object to Earth, and is the cluster most obvious to the naked eye in the night sky.
The cluster is dominated by hot blue and luminous stars that have formed within the last 100 million years. Reflection nebulae around the brightest stars were once thought to be left over material from the formation of the cluster, but are now considered likely to be an unrelated dust cloud in the interstellar medium through which the stars are currently passing.

The great globular cluster in Hercules, plus bonus galaxy NGC 6207 in lower right. M13 comprises a few hundred thousand stars 20,000 light years off; the galaxy is a thousand fold bigger and further out into space.
Tech stuff: Televue-85 with 1.08X Borg Flattener/ZWO ASI 1600MC/IDAS LPS D-2 Filter/SkyWatcher Star Adventurer mount guided. 4 second exposures captured as Live Stacks in SharpCap 3.2; 96 minutes total integration time processed in PixInsight. Imaged from my yard 10 miles north of NY City, SQM-L 18.7 (Bortle 7 suburban sky).
I let the camera take sub-images for an hour for this picture. I used 8 second subs with no darks at a low gain setting of 1241 (100-5000 Range.) Still lots of hot pixels without darks, but read noise is low so I could stack lots more sub-images than this 450x stack and still be within limits.
This data was taken in the middle of a metro area with very strong light pollution. Mag 3 are the dimmest stars you can see naked eye on most nights.
Not one of my best of this object because of all the LP, but it was fun to see it build up and get better and better as the subs were added in. I was using SharpCap 2.9's live stacking feature.
I should have shot darks before letting it rip on this object, but I did not think I had more than 20 minutes before the Dumbbell went behind the trees, so I skipped doing them. Oh, well… next time!
