  1. A doubt! Before April 1st, images are not accepted in the challenge? Only those that are made after that date? Best regards Avani Soares

    I've been giving a reedited in the photo and I think I could improve a little more!

    Jupiter, April 20-2018 This photo surprised me greatly because the seeing was extremely bad, so much so that in the capture program I could not see any fine detail. Then stacking it up! It must have taken a little good time that I did not even realize because it ended up showing enough details. https://www.astrobin.com/full/342616/0/?nc=
  4. Jupiter, transit of Europe

    Jupiter, April 11-2018, Transit of Europe Photo only for registration purposes, seeing was bad and did not allow me to pick up fine detail on the planet as I am accustomed to. https://www.astrobin.com/full/342425/0/?nc=user

    Hello, Sean! First of all I apologize for the delay, I was traveling. Before I had an ASI 224, I am currently using the ASI 290. By theory with my telescope (C14) it would have nothing to improve because with 224 I was already on the limit, but I think the practice often does not agree with the theory , I realized a gain in resolution with ASI 290 over 224 because its sensor has a smaller pixel size. In the other quests they are practically the same, high speed, low noise and great sensitivity, but as resolution is a fundamental factor in planetary I chose to keep it to the detriment of 224. Most of the great planetary photographers (not me!) Prefer to use monochrome cameras, but I opted for a color one because of the particularities of my local seeing. Explaining, where do I make the images the variability of the seing is very large, varies in a matter of few minutes from good to bad easily, as monkey cameras require more capture time I believe I will hardly have a long period of stability to shoot on the 4 channels . Already a color camera allows me to make 3 to 4 movies in the time that I would have to make a single with a mono and this increases the chance to take a 60 to 90 seconds of better seeing and thus get that photo that makes the difference. In principle for planetary photography there is no need for cooling, catches are brief, around 90 sec which does not get too warm. I do not know from news that the high frame rate introduces noise reading, would have to search. A colored camera should always use a filter, be it L, or even some IR. In the case of the L filter, it is automatically a UV-IR block filter, and by preventing the passage of the waves in the infrared and ultraviolet improves the quality of the image. Already if you want to capture in specific lengths in the infrared you can for example use an IR 685 or 742 that both ASI 224 and 290 are very sensitive in that region of the spectrum. Anyway a great camera for a fair price, thank Sam! Best regards Avani Soares

    Although not as good as the last, this photo still reveals many details.https://www.astrobin.com/full/341326/0/?nc=userIt is difficult to understand the criteria used in AstroBin, the previous photo in addition to showing more details became clearer, in compensation this was chosen "top pick" and the other not, for those who want to compare follows the previous: https://www.astrobin.com/340776/B/?nc=userI'm not complaining, just stating something I'd like to understand!

    Jupiter, April 07-2018 In fact this was a one-time lucky catch in 3 sacks. It was made through a fine mist but the atmosphere was very calm. A few minutes later began a violent turbulence and soon the time closed completely, It was lucky because I was just calibrating the equipment to try to capture the transit of Io. https://www.astrobin.com/full/340776/0/?nc=astroavani
  8. Storm spot visible on Saturn

    Unfortunately I've been without heaven here for over 15 days! I was the first to give the warning about this spot from a photo that was sent to me by a friend (Maciel Sparrenberg) here in Brazil. I'm every night stunned but the sky is closed at times. Damian got a beautiful picture using the Chilescope which can be seen here:

    Thanks Pete and Reggie! below an image made a little earlier in IR Pass 742.
  10. Jupiter, march 22-2018

    Registration done in medium conditions, so I had to extract too much of the processing to be able to bring details, which I do not like to do. I always prefer when the image is already good in the stacking done with sharpened AS! 2.
  11. Jupiter, march 08-2018 the best!

    Hi Sean! I have never used mono camera, actually the seeing on my site has a lot of variation in a few minutes. I think using a mono in this case is a disadvantage. With a color I can make several movies while with the mono would make one. So the chance to catch a good seeing on one of them increases and usually this is what happens. Last night for example among 12 films I only got one acceptable. If she had been wearing a monkey, she might not have gotten one. Plus I believe that the greater investment in equipment and time does not make up for the minimum gain difference a monkey could bring.
  12. Jupiter, march 08-2018 the best! Careful processing of the two best photos of the 12 captures made to get that GIF I posted on AstroBin Many details visible on the north pole and across from GRS. https://www.astrobin.com/full/337675/0/?nc=astroavani&real=&mod=
  13. Jupiter, GIF 1-2018

    Thanks for comments colleagues!
  14. Jupiter, GIF 1-2018

    First Jupiter Gif in the 2018 season. There were 12 movies each with 7500 frames. Each film I stacked 3099 frames, I processed and then I made the GIF or AVI using PIPP. March, 08-2018 C14 Edge + ASI 290 + L filter + PM 2X Avani Soares Parsec Observatory

    LOL, mine two years ago is orbiting, arrived before Juno!
