This is a very soft image, partly due to marginal seeing. My planetary images up to this point have been without a UV-IR Cut filter. Images posted after this date will be taken through a UV-IR Cut filter.

Montes Apenninus and Caucasus are the mountain ranges that bow downward across the image center, separating Mare Imbrium (upper half) from Mare Serenitatis (lower half). At the right of center, Crater Eratosthenes anchors the beginning of the Apenninus range, which occupies the first two thirds of the bow. After a brief interruption where Imbrium and Serenitatis connect, Caucasus continues. The trio of prominent craters near image center, from largest to smallest, are Archimedes, Aristillus, and Autolycus. And finally, Vallis Alpes and the southern end of Montes Alpes can be seen in the upper right corner. (Rükl 12, 13, 22 and 23)

Rus.: Соединение Марса и Нептуна 7 декабря 2018

Самая близкая (Марс) и самая далёкая (Нептун) к Земле планеты "сошлись" на крошечном участке неба.

Омский планетарий (vk.com/event174853487, afisha-omsk.ru/events/omskij-planetarij/13857-nabljudenie...)

заранее оповестил горожан, что 7 декабря Нептун будет всего в 2 угловых минутах от Марса (это расстояние в 16 раз меньше диаметра Луны!), что позволит наблюдать обе эти планеты в одном поле зрения при большом увеличении.

Максимальное сближение было предсказано в 20:40 местного времени (17:40 Msk).

Но я решил начать наблюдение к 19:00, когда планеты достигнут наибольшей высоты (30°).

К сожалению, небо вопреки прогнозу в это время заволокли облака. Шансов не было, и я ушёл на прогулку, во время которой ок. 20:00 обнаружил, что на Юге открылось чистое небо, в котором призывно горел ярко-красный Марс.

Примчался домой, собрал телескоп, монтировку, камеру... потом долго и безрезультатно настраивал монтировку, которая отказывалась удерживать телескоп (смазка подводит уже при температурах от -15°C) и его приходилось балансировать... найденной у детской горки картонкой (днём на ней кто-то катался, видимо;-).

Начать наблюдение удалось лишь к 21:30, когда и пик соединения был пройден и планеты уже существенно приблизились к горизонту - до 19°, рискуя "зацепиться" за крыши городских домов и утонуть в засветке фонарей...

Но видимое расстояние между планетами было всё ещё очень мало - на фото оцениваю его 0°3'7.69".

Планеты шикарно смотрелись в окуляре: яркий красный жёсткий и большой Марс и серо-голубой крошечный и немного аморфный Нептун.

Немного мешала дымка, зато у Марса она переотражениями лучей образовала роскошную "корону" (на фото убрал и теперь начинаю жалеть, да и Марс мне не разрешал ведь раскоронацию;-). Нептун и с дымкой вёл себя иначе - вместо короны в отражениях дымки иногда демонстрировал тоненькие одиночные лучи...

Две противоположности на крошечном участке неба.

Сфотографировать оказалось сложнее - даже увеличив светочувствительность так, что грязное городское небо превращалось в шумную почти осязаемую субстанцию, Нептун лишь едва начинал появляться... а Марс в это время терял свой цвет и превращался в белый шар, засвечивающий вокруг себя своей "короной" огромную часть неба.

Причём на хлипкой монтировке, которую едва-едва удалось стабилизировать, я был ограничен в диапазоне выдержек.

Пришлось фотографировать с разными параметрами (мультиэкспозиция) и даже прибегнуть к серийному сложению видеокадров (более 7,500 - личный рекорд;-).

В итоге эта невзрачная фоточка обошлась довольно дорого по затратам времени...

Зато момент свидания двух планет был запечатлён и у меня появилась "междупланетная лав-стори" ;-)

О героях фото (сравнить их размеры можно по ссылке ru.wikipedia.org/wiki/%D0%A1%D0%BE%D0%BB%D0%BD%D0%B5%D1%8...):

- Марс (назван мною ближайшей планетой;-)

Почитать дополнительно: ru.wikipedia.org/wiki/%D0%9C%D0%B0%D1%80%D1%81

Марс - четвёртая по удалённости от Солнца (за Землёй) и седьмая по размерам планета Солнечной системы; масса планеты составляет 10,7 % массы Земли.

Зато Марс настолько ближе к нам, что на фото выглядит крупнее.

А был ещё ближе - 27 июля 2018, такое противостояние наших планет называют Великим и повторится оно лишь 15 сентября 2035.

Сейчас Марс стремительно удаляется от Земли, но, в любом случае, его орбита - "соседняя" ;-)

Звёздная величина в момент фото 0.08m

- Нептун

Почитать дополнительно: ru.wikipedia.org/wiki/%D0%9D%D0%B5%D0%BF%D1%82%D1%83%D0%BD

Нептун - восьмая и самая дальняя от Земли планета Солнечной системы. Нептун также является четвёртой по диаметру и третьей по массе планетой. Масса Нептуна в 17,2 раза, а диаметр экватора в 3,9 раза больше земных.

Но огромное расстояние превратило этого гиганта в крошечную бусинку, едва различимую невооружённым глазом даже на загородном небе

Звёздная величина в момент фото 7.89m

Глаз человека - совершенный инструмент, позволяет легко видеть оба объекта столь разной яркости одновременно и уверенно различать их цвет.

Фотокамера в этом меня подвела, пришлось применять мультиэкспозицию и сводить на одном изображении варианты с существенно разными параметрами съёмки.

Старался приблизить картинку к тому, что видел. Вот только Марс "раскороновал", а у Нептуна отколол кусок с целый континент (присмотритесь внизу планеты;-). Впрочем, "отколотый" кусок повторился на ряде фото серии и, кроме того, почти совпал с положением спутника Тритон... но это не может быть Тритон, так как он просто не доступен в мой телескопчик, особенно при заданных выдержках (звёздная величина 14.08m).

Визуально в окуляр я никакого Тритона не видел. Тем не менее, камера "что-то там зафиксировала". А я решил сохранить ;-)

Фотографы они такие - сами решают, у кого корону отнять, а кому континент притаранить ;-)

My view from South Huntsville on August 15, 2020, just before midnight. Jupiter is prominent in Alabama skies now, easily found in the Southeastern sky during late evenings. Around 10 PM it reaches its highest point in our sky, to the South. As a Southern state, Alabama sees Jupiter rise high in our skies, affording us a view those farther to the North do not get. As a bonus, Saturn is nearby, bright, a little farther to the East. Mars rises in the East about the time Jupiter shines highest in the South; by October Mars will appear brighter in the sky than Jupiter.

Everything in this modest image leads to the Gassendi crater. Seeing was definitely not my best ally; The image of the Moon on the computer screen swayed from side to side as a result of atmospheric fluctuations. A lunar photograph does not remotely live up to the view through the eyepiece of my maksutov telescope; The poor vision that was evident with the camera was not noticeable to direct view and all was calm in the soft, deep contrast of the telescope. An intense glow towards the lunar terminator and then, the deepest darkness.

Gassendi rises above the Mare Humorum crowned by a circular rim, barely distorted here by the effect of foreshortening, and a small crater that breaks the edge, generating the visual idea of a diamond ring; Cracks come and go between cliffs and fissures forged in stone and lava millions of years ago.

Perhaps due to the turbulence or my own inexperience, the photograph is far from being a good lunar photo, but it preserves the spatial mystery and the indecipherable sensation of silence of a mythical lunar wasteland.

Un transito di Venere viene osservato dalla Terra ogni qualvolta Venere si interpone fra il nostro pianeta e il Sole, oscurandone una piccola parte del disco; durante un simile evento, un osservatore può vedere Venere come un disco nero che attraversa il disco solare.

I transiti di Venere sono tra gli eventi astronomici predicibili più rari e avvengono con uno schema che si ripete ogni 243 anni, con coppie di transiti separate da un intervallo di 8 anni che si ripetono in periodi più ampi di 121,5 e 105,5 anni. La penultima coppia di transiti avvenne nel 1874 e nel 1882. Il primo transito della coppia attuale è avvenuto l'8 giugno 2004, mentre il successivo è avvenuto il 6 giugno 2012. Quest'ultimo non è stato visibile nell'area atlantica (tra l'Argentina e i paesi dell'Africa occidentale), mentre ha raggiunto lo zenit nell'area polinesiana dell'Oceano Pacifico; in Italia, come in quasi tutta Europa, è stato visibile all'alba.

I prossimi transiti avverranno l'11 dicembre 2117 e l'8 dicembre 2125.

The Sun is just beginning to set on the easter shore of Mare Fecunditatis, the large flat plain at center image. Crater Langrenus is the "fresh" crater on the central eastern shore. Crater Petavius is the more worn and overlapped crater on the southeastern shore. The waning gibbous moon is just two days past full. Seeing was horribly poor at the time of capture.

This picture was captured using a telescope with a Hydrogen-alpha (Hα) filter. This lets us see the Sun's chromosphere. As a result we can see many solar features, such as sunspots (seen here as black dots, plage (beach), seen here as bright white areas, filaments (black lines) and prominences (seen around the edge). Although these features may look small, we must keep in mind that the Sun has a diameter of 840,000 miles (compared to Earth's 8,000 mile diameter).

Clouds prevented me from seeing and recording the actual occultation of Saturn by the Moon. This was the closest I got to the event before being clouded out.

I shot this with the C14 on Cerritos College campus with a ZWO ASI224MC, ADC, and UV/IR cut filter. SER videos were captured using FireCapture 2.7. This image is produced from the best 40% of 45 frames taken at 1109 UTC. Those frames were stacked in AutoStakkert, and the results were processed in PixInsight and GIMP.

This image gives a pretty good idea of how faint Saturn is compared to the lunar surface. Even though Saturn is considerably larger and more reflective than the Moon, it only gets about 1% of the light that the Moon does because it is about 10 times farther from the Sun.

Over the past several years, I have had difficulty processing my color moon photos in color. My computer simply balked at stacking the large data files, so I opted to present them as monochrome images. Recently I overcame that problem, and I have started to revisit some of those old data sets, restoring to them their color.

Sunspot AR2965 has a 'beta-gamma' magnetic field that harbors energy for M-class solar flares.

Scientists classify solar flares according to their x-ray brightness in the wavelength range 1 to 8 Angstroms. There are 3 categories: X-class flares are big; they are major events that can trigger planet-wide radio blackouts and long-lasting radiation storms. M-class flares are medium-sized; they can cause brief radio blackouts that affect Earth's polar regions. Minor radiation storms sometimes follow an M-class flare. Compared to X- and M-class events, C-class flares are small with few noticeable consequences here on Earth.

Although Crater Copernicus and its southern ejecta field are the dominant features in this image, it is about the Apollo 12 and 14 landing sites. Apollo 12 landed in Mare Insularium, and Apollo 14 just outside of Fra Mauro's north rim. (Rükl 41)

"Clavius Crater and Points South"

April 22, 2021, 23:18 CDT

Moon age 10.3 Days

I have been on a craters kick for a day or so. Anyone who pays attention to these is wise to expect a photo of Clavius crater to show up sometime. I can’t help it – Clavius is a beauty, and it dominates a region offering dramatic contrasts of light and shadow.

This image catches Clavius under pretty high-angle light, like late morning. The craters to its South are increasingly shadowed, until it becomes difficult to separate them from each other and from the edge of night. Here and there, first light catches the peaks of mountains emerging from the gloom.

Seeing conditions were about 4/5 at the time this video was obtained. I did not venture using a focal extender to magnify the image because I had a nice focus locked in and did not want to risk losing it: instead, I opted to use a smaller region of interest in FireCapture (1000x800px, an in-camera crop) on this one.

The best 12% of 5779 video frames were used in creating this image.

I omitted my usual step of pre-processing the video in PIPP software, as tracking was good. Instead, the video was stacked without pre-processing with Auto Stakkert!3 software. Wavelets and histogram adjustments of the AutoStakkert!3 output image were done with Registax 6. Final toning, minor cropping and watermarking were done with Camera RAW and Photoshop CC 2021.

In questa foto, due grandi macchie solari segnano il progressivo aumento dell’attività solare, che viene misurata in cicli di undici anni a partire dal 1755. Attualmente il Sole si trova nel venticinquesimo ciclo, iniziato a fine 2019, e sta progressivamente raggiungendo il massimo, che avverrà nel 2025. Con l’aumento dell’attività si manifestano forti perturbazioni magnetiche, con la comparsa di regioni attive sulla superficie. In questa immagine della cromosfera solare, ripresa il 19 Gennaio 2023 alle 12.26 (Tempo Medio dell’Europa Centrale, TMEC), sono visibili due grandi regioni attive catalogate come AR3190 (in basso) e AR3191/AR3192 (in alto). Quando osserviamo la cromosfera con un filtro che isola la lunghezza d’onda dell’idrogeno ionizzato (H-alpha) queste regioni appaiono come una complessa associazione di zone brillanti (facole) e scure (macchie). La macchia associata alla regione 3190 è una delle più grandi apparse nell’attuale ciclo solare: è grande quattro volte la Terra è potrebbe essere vista ad occhio nudo, naturalmente utilizzando una adeguata schermatura per gli occhi.

This is a photo of the Mare Insularum region of our Moon. It includes the large, prominent crater Copernicus (upper right), and the smaller craters Kepler (center left), Lansberg (center bottom) and Reinhold (between Lansberg and Copernicus.

Copernican System craters, named for the prime example, Copernicus, are all features that have originated over the most recent 1.1 billion years. These craters have sharply-defined features, terraced interior crater walls, prominent central peaks, high outer ramparts made of excavated materials, and extended bright ray systems surrounding them that radiate across the surface of the moon, covering other older features.

The rays are bright because they are comprised of materials that were blasted outward from the interior of the Moon in the moments following the impact of a meteor or asteroid. These materials have not yet been subjected to the "weathering" and darkening effect of eons of exposure to solar radiation and micrometeorite bombardment.

Craters Copernicus and Kepler illustrate these features well. Examine these craters and their surrounds and note how the impact events that formed them transformed the face of the Moon. Close examination will reveal myriad tiny craterlets around the primary craters. These craterlets were formed when material, ejected at high speed by the impact that created the primary craters, fell back to the Moon. They are often arrayed as linear features, little chains of craterlets, radiating outward from the primary crater.

Seeing conditions were at best 3/5. High Jet stream winds negatively affected what might otherwise have been outstanding viewing conditions.

Taken with a Canon 70D DSLR and TMB92L refractor. This is the result of 29 images stacked with AutoStakkert! and processed with Astra Image Pro and Adobe Photoshop CS6.

I wantet to test the big telescope and took some shots of the nearly full moon. I took (3x3) nine panels and stacked them in Autostakkert.. Best 30 of 1000 frames per panel. Out of curiosity I researched the landing site of the japanese "SLIM" lunar lander that is currently active up there.

Bei klarer Nacht wollte ich mal mit der großen Optik auf den Mond halten. Irgendwie kam ich auf die Idee, mal die Landestelle der japanischen Mondmission "SLIM" herauszusuchen, die habe ich hier mal nach bestem Wissen markiert. Die Landefähre konnte ich auf den Bildern nicht entdecken 😁

Technik : Die Aufnahme ist aus einzelnen Panels (3x3) zusammengesetzt. Für die neun Einzelbilder wurden jeweils kurze Videosquenzen mit je 1000 Bildern verwendet, aus denen die jeweils besten 30 Bilder für das Stacking ausgewählt wurden. Software: Autostakkert, GIMP.

The ACEAP 2019 team first saw this lovely crescent moon with brilliant earthshine as we headed down from the ALMA technical building to the residencia for dinner. I rushed up to my room for my camera & tripod. I thought that I'd missed the moment, but I couldn't head home without an image of the Moon from a world upside down. Dust near the horizon dimmed the earthshine. The Moon sank behind a featureless flat topped ridge, instead of a nearby volcano...

Without my tracker, only one set of earthshine exposures was clear. The Atacama has wonderful contrast between the foothills of the Andes and flat desert. With the HDR image put together, it captured the flatness of the desert and color of the dust. This almost monochromatic image captures the moment; I can almost smell the dust. This rendering is lightened a bit to show well on phone screens, if you print the full resolution image you will probably want to adjust the exposure.

Sony a6300 with Nikkor 180mm f/2.8 shot at 5.6 with a 1.4x teleconverter. Crescent data exposed 1/50 sec at ISO 1600. 88 frames 1.5x drizzle stacked in Autostakkert 3. Earthshine and ridgeline data exposed 30 sec at ISO 200 with 5 images stacked. Final HDR composite and crop in photoshop.

Astrophotographers, get yourself to the Atacama in Chile. With no forests to burn, humidity of 3% and 0.3 arc second seeing, the Atacama is second only to the Antarctic and low earth orbit for imaging possibilities. Chile has warm welcoming people, great food, and lots to see and do when you are not looking up. Thanks again to AUI, the NSF, and their partners in giving me this opportunity.
