Excellent image Lucas! I also have a photo similar to that friend Ruud, but it was made from the assembly of one of mine, LOL.

I appreciate all comments! In fact the C14 is unbeatable due to the opening Geof friend. The C9.25 is considered to be optically speaking the best of the SCT, but against the brute force of 14 "not what to do. I am using the C9.25 because I am on vacation on the coast of Rio Grande do Sul, at home I only use the C14, even due to the ease of having everything ready for use. I spent many years behind a teleport with good portability, I believe that now I found the best compromise between openness and practicality.

With good seeing everything is possible. Even with low planet and high humidity many details can be visible if the atmosphere is calm. In this photo of Mars we can see several formations that can be compared with the central photo obtained in Virtual Planet Atlas. There are two cloud formations, one over Chryse Planitia and the other over Isidis Planitia. However, what draws the most attention is Hellas Planitia located to the south that many may think is the South Pole in visual observation. A photo that I really liked for a distance of 2 AU and only 4.7 "of arc. https://www.astrobin.com/full/q4q5qq/0/?nc=user

Spending hours capturing, then a few more hours to process, when it's almost over to find out that a few pieces were missing due to misalignment, is what I call a real crime.179 Mb mosaic from 36 frames, stacking 185 frames per movie from a total of 1200 frames in each movie.AS! 2 + Irtan + iMerge ProcessingImage reduced to 5000 X 5000 pixel.Despite this novice mistake, I chose to post the image and thus make it clear to my colleagues that we must be very careful not to lose a few dozen hours of work.

God hear you friend Reggie! Note that the capture was made with C9,25!

Hello friend Ruud! Luckily I wasn't in the car, professional appointments kept me from going. My friends were going to a star party. One only suffered scratches, 2 were hospitalized for 15 days, injured badly and the driver of the other car that caused the accident unfortunately died on the spot. Life has ups and downs, it can always surprise us on the way.

LOL, I usually cry on my stomach as they say in Brazil!

Median seeing conditions and high humidity, which stole Long Pass filter resolution. Stacking 2555 frames out of a total of 10,000. https://www.astrobin.com/2zopgm/

Thanks my friend!

Hello! Uranus is actually better located for northern hemisphere observers. I'm 30º South and for me it gets quite low. I think it must be almost over your head!

Thanks my friende Pete!

Uranus is the seventh planet in relation to the sun and was accidentally discovered. Although it is visible to the naked eye, the planet has long been mistaken for a star because of its obscurity and slow orbit. Due to the distance to Earth and the few exploratory missions, much about Uranus remains a mystery to us. But what has already been discovered makes this planet one of the most intriguing ever known. Between 21-year seasons and diamond showers, see some of the facts that make this planet one of the most fascinating in the Solar System. Like Venus, the rotation of Uranus rotates from east to west, the opposite of the direction in which the earth and most other planets rotate. In addition, the planet's rotational axis is tilted at an angle almost parallel to its orbital plane, making it appear to be spinning sideways. Scientists theorize that this rotational anomaly may be the result of a gigantic collision between Uranus and another celestial body, such as an asteroid. Due to this strange rotation of Uranus, the seasons on this planet last about 21 years! This causes huge variations in the amount of sunlight that the planet receives at different times of the Uranian year. Think of a planet where summer lasts about 21 years, receiving sunlight all the time, while winter has the same amount of time, with the planet in total darkness and freezing cold. In Uranus, day and night exist only during spring and autumn. These strange seasons pass through Uranus during its year, which corresponds to 84 Earth years. Meanwhile, the day only lasts 17 hours. If you think Saturn is the only planet in the Solar System to have beautiful rings, then Uranus also has two sets of its own, totaling 13 rings! The innermost set consists mainly of thinner and darker rings, while the outermost one is made up of two colored rings, one blue and the other red. In addition, Uranus has - as far as we know - 27 moons, and instead of being named after deities of Greek or Roman mythology as usual, they were baptized with character names created by Willian Shakespeare and Alexander Pope, such as Miranda. , Oberon, Puck and Ariel. The speed of Uranus's orbit is 27,400 kilometers per hour and its mass is 14.5 times that of Earth. The atmosphere of Uranus consists mainly of hydrogen, helium and methane. The surface temperature reaches negative 216ºC. The bluish color results from the absorption of red light from methane in the upper layers of the atmosphere. In the attached photo we can easily see the lighter region of the South Pole, inclined practically 90º as the costumes dictate. Capture made under median seeing conditions, using a Long Pass 610 nm filter, the lighter polar region was very evident, while the dark zone the different shades are probably processing artifacts. https://www.astrobin.com/l5vk98/B/

Testing for the first time a C9.25 after an accident during the collision of two cars. He hears some wrinkles and scratches on the OTA but the optics miraculously came out intact. It was enough to crumple in part so that there was no obstruction besides collimating that the quality remained unchanged. Congratulations to Celestron for building such tough phones. Mosaic from 13 frames in iMerge. I invite colleagues to look at full resolution on astrobin: https://www.astrobin.com/full/jqyyj8/0/?nc=&real=&mod=

I took the liberty of slightly processing your image using Fitswork and have to recognize once again that for just 14 degrees it looks great!

14 degrees !!!!!!!!!!!!! At this altitude I can do absolutely nothing, you are to be congratulated. I have a C9.25 now, unfortunately end of year for me is a lot of work, so just next year I intend to test it carefully.

A tempting invitation friend Reggie! Unfortunately I can't do something like that, but I would love to. Not so long ago a friend came back from the US, passed Lowell Observatory and was eager to tell me that people asked for me there. They already knew my photos! I was very happy, it was better than winning an APPOD, Lol.

A beautiful picture! I would very much like to have a setup to catch the whole sun, but unfortunately both the telescope and camera are not suitable for that. It's a pleasure to see your work my friend!

Hello John! I am very interested to know the conclusions you get about this Cassegrain! I am very interested in getting one for my field planetariums because the C14 is unbearable. I appreciate any communication you make about it!

My Friend ..., the wind was coming in gusts so strong that most of the movies were lost because the planet simply left the capture area.

And only a Baader solar leaf with a Green filter was used, I didn't expect so many details myself. But what I liked was that the planet was very well defined.

I am sad that you missed this rare opportunity friend Ruud! I made more than 20 films, only this one was saved, mostly the gusts of wind threw the planet off the capture screen.

A modest capture made in a very difficult situation. There were about 20 films, most of them lost due to the gusts of wind that moved the planet out of the capture screen, in addition to many clouds passing which made light control a real adventure. After all, one is better than nothing, at least I managed to register this rare event because the next, I do not know if I will still be here. https://www.astrobin.com/full/erk987/0/?nc=user

Great job, the definition of the planet was excellent! Here unfortunately the conditions were not suitable for a good result!
