Additional ultra wide-angle electronic viewfinder

Additional ultra wide-angle electronic viewfinder Attach a 3 cm and 8 cm viewfinder to the self-made 45 cm newtonian telescope and put it in the field of view of the telescope before the automatic introduction setting. After the automatic installation is set, it will be done on the personal computer without using it. Since a long FL is required when shooting a planet, an electronic viewfinder with an ASI174MM attached to a 6 cm (FL / 420 mm) refraction and PHD2 are used together. Since it is a telescope mounted by force, tracking of the equatorial mount is not good, and it is necessary to monitor it with a handbox during planetary imaging. Planet imaging is also convenient with auto-guide. It seems that auto guide can be done with Firecapture, but I don’t use it because it’s not working well. This time, while organizing the equipment, the DMK camera and […]

Jupiter June 17, 2021

Jupiter 2021-06-17 (UT) The sunny season of the rainy season. I could see the Milky Way on a clear night, but it was a terrible seeing. It was the longitude where I could see GRS, so I took a image with patience. The 45cm telescope cannot be used when seeing is bad!

Pillar stand

The other day, I got a pillar stand from friend. This stand is for Nikon’s 12cm binoculars and is tall. The pillar stand of the JP equatorial mount of C14 that I used so far is low, and I looked into it with a difficult to watch on Jupiter and Saturn, so I replaced it with this high pillar stand. I 1orderd it and had it processed with a tapping screw. After processing paint, I replaced the low pillars with Nikon pillars and it was ready to use everything. The height of the equatorial mount has increased, making it easier to see low planets, but when viewed from the side, C14 telescope over from the slit. The storage fits sideways (laughs)!

Jupiter　 2021-06-11 (UT) It was frustrating because of the many clouds and frequent interruptions in imaging. Seeing is stable and the inside can be seen well. The white spot on the STB in the center on the south side is [BA], which is less bright and slightly yellow than the white spot on the south side. Its can clearly see the distinction like the clear coastline of NTBn in the Northern Hemisphere.

Its can be seen up to high latitudes in the Southern Hemisphere of the CH4 image. The IR image shows the complexity of the belt near the center.

Jupiter 2021-06-07 (UT) Seeing is a little good, but there are many clouds passing through. It seems that there are few optical axes. On Jupiter’s feature, GRS (Great Red Spot) can be seen on the far left. The orange color of GRS has become lighter than last year. In NEB, you can see a large bright part with a complicated feature (IR. IR-1000).
