deepsky M42 C14 LX 200 768x465 - First altazimuth mount mode

First altazimuth mount mode

(C14 + Lx-200) For the first time, I took an image of M42 in altazimuth mount mode. There is no de-rotater device to correct the rotation of the image, but it seems that I can take image for 2 minutes. Tracking the altazimuth mount moves as if the direction and altitude were blurred, so it may not be possible for a planet with resolution. It is not a smooth tracking like an equatorial mount, but I think it has little effect on visual inspection. There is no balanced waist, and the stable balance is truly good. Considering the image, the fork-type equatorial mount is probably good. I can understand the feelings of the former owner!

C / 2021 A1 Leonard Comet December 11, 2021

C / 2021 A1 Leonard 　 2021-12-11 Mizuki, Hitachi City Comet Leonard rising from the horizon of the Pacific Ocean was nice to see floating in the waves. This is the first time I’ve seen Comet West since ancient times. Is the luminosity of the comet a 5th magnitude star? I want it to be a little brighter. When the twilight begins, the sunrise in the eastern sky is very beautiful! !!

LX-200 16-inch altazimuth mount

The appearance of the hybrid telescope of the LX-200 16-inch altazimuth mount (Autostar II) and the C14 has been completed. The direction of the initial alignment function built into GRS does not point to the north. Is it just a matter of settings? I do not understand!

C/2021 A1 Leonard Comet First half

C / 2021 A1 Leonard Comet 2121-11-26-12-05 45 cm / 20 cm Newtonian ASI071MC Pro The progress of the comet approach (first half) is summarized. There was moonlight in November, and the image of the tail was faint, but after December 3, there was no moonlight, and yellow dust can be clearly seen. The approach to the globular cluster M3 became a beautiful image. I am looking forward to future changes.
