20020-04-30 (UT) Jupiter image The seeing condition was good at the beginning of the imaging, but gradually deteriorated, but an image was obtained. In UV and CH4 images, the black and white of the feature is reversed, which indicates the height of the feature. In the CH4 image, the white pattern is higher than the surroundings and the black feature is lower. On the contrary, in the UV image, black may be absorbed.
20020-04-28(UT) Jupiter image It was a little haze, but seeing condition was a little better. Visually check the GRS, the color is orange, crisp shape. Since J20200428-2 is an image in the blue sky before sunrise, it has no contrast and is rough.
2020-04-25 (UT) Jupiter image captured by Nasu Observatory (40cm Cassegrain).
Jupiter 2020-04-23 (UT) As usual, seeing is bad, but I am taking routine images. GRS is visible. EZS has a light section. IR1000 in the center (1μ image can cover poor seeing
Jupiter/ 2020-04-20 / Jupiter after the rain. Seeing condition is bad, but it is impossible to take image.
Jupiter 22020-04-07 Jupiter at dawn, this year seeing condition is quite bad . Jupiter altitude is too low at 30 degrees.
Jupiter and Pluto 2020-04-08 03:20 (JST)Sony α7s (IR modification) ISO6400.12x1s45cm F4 (MPCC)Dwarf planets Pluto and Jupiter are aligned at 0.8 °. Pluto is 14.3 mag, full moon, too bright.
Venus and Jupiter (March 16-17)I cannot use the controller of the 45㎝ reflector equatorial mount, and it is compatible with a personal computer, but it is very difficult to use.The dawn planet observation season has begun, but Seeing is terribly bad and we have to give up.
Jupiter Great Red Spot Changes from 1994-2019. These 25 years of Jupiter images have shifted from emulsion film photography to digital imaging and are up to the present. The shooting method and subsequent processing have changed completely, and the resolution of Jupiter images has been greatly improved. In addition to color images, images can be easily obtained on UV.IR CH4, and observation images have changed
. Jupiter Great Red Spot / Changes from 2001-2019. C8, C14, 32cm and 40cmNewtonian reflector. 2004-2014 taken on Cebu Island. GRS density change and size reduction can be easily understood!
