2021-09-21 01:08 (JST) Experience the phenomenon of the International Space Station (ISS) crossing the moon for the first time. Chinone Hitachiota City, Ibaraki Prefecture. I can’t observe it at home. We enjoyed it together at the home of my friends. Thank you. You can see the atmosphere with the images and videos.
Jupiter 2021-09-20(UT) Clear sky night. Seeing is a little good. Longitude of the Great Red Spot (GRS). Lifts can be seen in NEBs, and long festoons stand out. A group of white spots connected to the south side came to GRS.
The 45 cm equatorial mount is as easy to store as a covered wagon, and I’m worried about this typhoon! , The appearance in the daytime is poor, but it is divided into the main observer.
Jupiter 2021-09-16 (UT) It’s night and it’s a sunny night, but seeing is too bad and the image is out of focus. This is the limit of imaging.
Jupiter 2021-09-13 (UT)Jupiter was finally image with many clouds. GRS is on the far left. On the Jupiter feature, Jupiter flash impact (7:39 am on the 14th) was observed in Brazil after one rotation of this longitude. You can see the bright flash and position by arranging the flash images.
While organizing old CDs, a digest image of a 20th century planet came out. It is a combination of 32 cm newtonian+ cooled CCD (Teleris). In the era when there was no digital camera for astronomical colors, all colors were RGB composites. It was around the time when the Great Red Spot on Jupiter was pale. The quality is one rank lower than it is now, but I remember the bright vitiligo that looked like Saturn’s EZ.
Jupiter 2021-09-10 (UT) Jupiter in a short time between clear clouds. I am lucky to be able to take an image through a thin cloud. The longitude and SEB near the Great Red Spot (GRS) are complicated. The distorted south side of the GRS shape in the IR image is probably due to the surrounding bluish feature and poor seeing
Sun 2021-09-10 During the daytime, I aligned the optical axis of 45 cm newtonian, and in order to check the optical axis condition, I took a image of the entire sun with an eccentric diaphragm with a diameter of 17 cm + a solar filter. You can see the sunspots, and the solar activity will be revived! , Daytime imaging is hot and hard!
Jupiter 2021-09-07 (UT) Jupiter was in the south (south) at 10 pm, and it was a reasonable time zone. It was cloudy due to the influence of the autumn rain front, but I was able to take image through a thin layer. Seeing is bad and there are no details. Jupiter instead of Player one’s Petune-C II. Color camera Sony IMX464 (color) Format: 1 / 1.8 type (7.9 x 4.5 mm) But is it possible to capture UV, CH and IR color images with a single camera? I tried! Although it is thin, the sensitivity of the IR region is high, which is more than double that of 290MM. IR-1000 is more than 3 times. UV sensitivity is higher at 290MM. There is a peculiarity in the hue of color images, but you can use it by adjusting it. I’m happy that there is little noise!
