Saturn, the 6th planet, just hours before its 2022 opposition. The brightest portion of its magnificent ring system extends from 4,300 to 50,000 miles (7,000 to 80,000 km) away from the equator. The Cassini Division appears prominently as a dark band in the rings. 5 Saturnian moons are also visible in this field of view. Its largest moon, Titan, is the only other place in the Solar System with bodies of liquid on the surface (rivers, lakes, and seas).

 

After several weeks of cloudy nights, I was shocked to see clear skies on the night of opposition. I didn't get a chance to test my new equipment beforehand, so this was a great example of "figuring it out on the test" (my motto from high school). My new planetary imaging setup uses a different telescope, camera, and Barlow compared to last year. The only thing that hasn't changed is the mount. I expected low-quality results based on how little time I had to sort everything out, but this turned out way better than I expected!

My first attempt imaging Jupiter.

taken with a small refractor (72mm, f=420mm) with a Raspberry Pi Camera

Just a quick imaging this very early afternoon. It was challenging to find the extremely thin Venus crescent, but when I did my smile was just as wide as the crescent itself :D

Processing was another challenge, PIPP couldn't do much with the video, Autostakkert also was struggling. But a little trick helped, saved the video into individual frames and that helped a lot.

This is the thinnest Venus I have ever photographed. Great day! :)

Rupes Recta, the Straight Waal on the Moon, Celestron 8 telescope with ZWO ASI120 MC-S camera. Composite of 80 frames out of a 4000 frame capture. Processing with Autostakkert and Registax.

Sky-Watcher Star Adventurer mount (it has a lunar tracking mode available) + Sky-Watcher Evostar 72ED (72/420mm) + filter wheel with Baader LRGB filters set (for the transit UV/IR filter was used) + Barlow 2x + ZWO ASI174MM camera. To get the color shot R, G and B channels, 3000 frames per each (and 3000 more through UV/IR filter, which was used as L channel later on). As the Moon doesn't fit the field in this configuration, two panels were shot. ISS cropped out manually using Gimp; stacked and sharpened using cvAstroAlign (25 frames out of 70 went into stack); later on got ISS out using Gimp. Moon stacked using AutoStakkert! 3, then aligned the channels using PlanetarySystemLRGBAligner, then combined to obtain RGB using ImageMagick; L channel added in Gimp. Then assembled the panorama using Hugin. Post-processing in RawTherapee. Added ISS back using Gimp

2018-10-14 Stack of 141 of 288 images. Sony A77ii, Minolta 400/4.5 + 2X TC

Taken with a Coronado PST and 2 x Barlow + ASI120MC camera.

 

I was imaging prominences around the entire solar disc between 11:00 - 11:15 UT. Between 500 and 1,000 frame videos were captured and the best 250 frames were stacked using Autostakkert! 3.

After imaging an ISS solar transit, I shot some more video of the Sun in white light. I caught AR12833 on the upper left, which rotated into view a few days ago, but also very faintly to the right is AR12832 which is about to rotate out of view on the opposite side. Photo taken from Oxfordshire, UK with a William Optics 70mm refractor fitted with a Thousand Oaks glass solar filter. The camera was an ASI120MC. A 2,000 frame video was captured using SharpCap and the best 75% of the frames were stacked using Autostakkert! 3. Stacked image was processed in Lightroom, Fast Stone Image Viewer, Photoshop CS2 and Focus Magic.

Taken from Oxfordshire, UK with a William Optics 70mm refractor + ASI120MC camera fitted with a 3x Barlow. The mount was my Skywatcher AZ GTi on a tripod. I had to use my portable set up because the Moon was too low to get above the trees from my permanent pier or from the observatory shed.

 

I grabbed the telescope because I wanted to capture the Lunar X and V on the 44% Waxing Crescent Moon before the Moon set. I had to dodge endless patches of cloud which were making my life miserable! Given the conditions I'm really really happy with the photos I got!

 

I captured a 1,000 frame video using SharpCap. I stacked the best 50% of those frames in Autostakkert! 3, then processed the images in Lightroom and Fast Stone Image Viewer.

Taken with a Skywatcher ED80 Refractor fitted with a Baader Astrosolar Filter and a Canon 600D at prime focus ( 600mm ). Best 10 of 30 jpgs stacked with Autostakkert 2 after centering and cropping automatically with PIPP.

I caught the crescent Moon under a tree branch on a beautifully clear night in Austin Texas taken 2019-06-09 04:27 UT. Sony a7 iii with a vintage Nikkor 300mm ED telephoto and 1.4x teleconverter. Exposed 1/25 sec at ISO 640 at f/16.

Best 4 of 25 images drizzle stacked in Autostakkert 3, deconvolve in Lynkeos with final crop and exposure in Photoshop. Tree limb light painted in 15 sec exposure.

Taken from Oxfordshire, UK on Friday 29th May 2020 when the Moon was at 42% illuminated waxing crescent phase. I love the crater shadows during this phase and the shadows on Walther and La Caille were looking fantastic. You can also still make out the Lunar X (I shared a daytime photo of this yesterday) which is a clair obscur effect. This is a pretty aggressive crop from the original image.

A lunar close-up showing Crater Plato (the large crater in the lower right of the image). This is a lava-filled lunar impact crater on the northern hemisphere of the near side of the Moon. It has a diameter of 101 km and is about 3.84 billion years old. It is located on the northeastern shore of the Mare Imbrium, at the western extremity of the Montes Alpes mountain range. In the mare to the south are several rises collectively named the Montes Teneriffe. To the north lies the wide stretch of the Mare Frigoris. East of the crater, among the Montes Alpes, are several rilles collectively named the Rimae Plato.

Saturn is not only nice for its rings but it works as a miniature solar system as seven of its Moons can be imaged with modest equipment.

 

Mimas and Enceladus were too close to the planet so they are not in the photo. The orange color of Titan is visible. The unlabeled thing is a star.

Near to the center of this photograph is the Apollo 11 landing site where man first set foot on the surface of the moon in July 1969. This photo also captured the craters Armstrong, Aldrin, and Collins which were named in honor of the three Apollo 11 crew members (Neil Armstrong, Buzz Aldrin, and Michael Collins).

 

Slightly below and between the craters Aldrin and Collins is a small group of three craters that form a near right triangle and the topmost of these three craters is officially named Sabine C (although an effort has been made to name this crater after the late broadcast journalist Walter Cronkite). The rightmost crater in this small group is informally known as the "Cat's Paw." Among the lunar craters that are able to be seen with medium-sized amateur telescopes, the "Cat's Paw" is the closest to the Apollo 11 landing site (which is only about 7km to the east -- right -- of the "Paw").

 

Photographed on the evening of April 13, 2016 using a 5 inch aperture refracting telescope (e.f.l. 990mm, f/7.8) and a ZWO ASI178MM-Cool camera (using a stack of the best 40% of 1000 frames). Image processing done with Autostakkert!, Registax, and Photoshop CC2015.

My take on the super blue moon. K3iii x 55-300PLM (100 takes staked in Autostakkert). Bit of LR + PS for the stars. 9:35 PM UTC. Laurentides, Québec, Canada.

The Sun was playing hide & Seek with clouds today, but I managed to grab a few videos in the gaps so I could test out the new Baader Solar Continuum Filter that I bought from First Light Optics a few weeks ago. This filter helps to reduce the effect of atmospheric turbulence and I could definitely see that on screen. It also increases definition and brings out the granularity of the Sun's visible surface. I have wanted one of these for about 9 years so I'm super thrilled to finally have one! I'm looking forward to playing with it some more.

 

Taken with a William Optics 70mm refractor fitted with a Thousand Oaks glass solar filter. The Camera was an ASI120MC. Mount was an EQ5 Pro, tracking at solar speed.

Saturn reached opposition on August 14. This session took place on the night of the 12/13 of August - just before Earth moved between the sun and Saturn, placing the planet opposite the sun in our sky and when it appears at its biggest and brightest. I used frames above the 75% quality threshhold I arbitrarily chose. This composite image uses two different exposures, one for the planet and one for the moons.

Mare Crisium, Mare Fecunditatis, and the surrounding area are lit by sunlight coming in at a low angle in this pair of views. The top image was shot around 2020-09-04 0620 UT and the bottom image around 0900 UT. Look closely at the length of shadows in each - you can see how the Sun has sunk closer to the horizon during the time between the two images.

 

The north edge of the Moon is at the left in these images. Looking along the terminator, some craters that stand out are Geminus and Cleomedes to the north and Langrenus and Petavius to the south. The central peaks of Langrenus and Petavius show the change in the length of their shadows particularly well.

 

Each image is a composite from stacks of SER files shot with a ZWO ASI120MM with a #58 green filter. The scope was a Celestron Edge HD 925 at f/10. Stacking in AutoStakkert with the best 75 of 300 frames; individual images merged in Photoshop for the composite; final processing in PixInsight.

New and improved version! WinJUPOS derotation leads to a much sharper result. This is a derotation of 5 images (500 frames each).

 

Jupiter, the largest planet in the Solar System, about 3 weeks after its 2022 opposition. The Great Red Spot, visible in the southwest, is a giant storm with a diameter larger than Earth. Wind speeds in the storm peak at 268 mph (432 km/h).

 

This is one of my top 3 Jupiter images from the 2022 season. Using this 6" SCT with a planetary camera is so much fun, and the results are shocking to me. I could have never imagined getting images this sharp when I started this hobby back in 2018!

In alto a destra è visibile il cratere Gassendi (diametro 111 Km),con all'interno alcuni piccoli crateri e alcune fessure chiamate rime, più a sud invece si trova il mare Humorum ( 419 Km), più scuro e e con pochi crateri al suo interno.

La zona a ovest di Gassendi nell'immagine è ricchissima di dettagli e qui nella foto si vedono bene a causa della vicinanza al terminatore, che è la linea di separazione giorno/notte ed è la zona in cui la luce solare arriva solo a sfiorare le parti alte dei rilievi lunari.

Calcium image is result of experiment to see how the solar film would act as ERF with Lunt B1200 CaK module,this time C9.25 was used at f/10 but camera had to be 2x2 binned as well as using ROI so as to reduce exposure time and increase FPS rate to around 10-15.

Hoping to catch a total lunar eclipse in about 9 days but this time, I will have to be mobile to catch it all - neighbour's houses and trees will interfere as the Moon sinks down towards the horizon in the UK.

 

So rather than use my 900mm telescope and heavy tracking mount, I plan to go mobile with a DSLR, long camera lens and extender (840mm focal length) on an AstroTrac tt320x-ag tracking mount.

Petit souvenir du rapprochement Lune - Vénus de ce matin,

La lune a occulté Vénus en cours de matinée, mais ni la météo ni le timing ne m'ont permis de suivre cet évènement.

Ce sera donc une petite photo souvenir, à 400mm de focale donc avec peu de détails, mais ça reste un joli moment au sein de la mécanique céleste à photographier 😊

Didn't think I'd get to see anything at all since it was overcast and but the clouds were thin enough at times for the h-alpha wavelength to cut through. I captured as much as I could. This is a stack of about 450 frames. I have more that I need to process and probably add on to this.

 

I have a video showcasing my gear and capture process here: www.youtube.com/watch?v=mlLqKOOljcs
