Vixen, a Japanese astronomical telescope manufacturer, may be a familiar company name to those who take astronomical photographs. This is a company with a high reputation in the industry, having produced many luxury telescopes used in Tianqian photography.
In this video, I'm going to talk about Vixen's R200ss, a reflecting telescope dedicated to astronomical photography. The first thing to conclude is that in order to use it to live up to its name, you need to put a lot of effort into tuning it.
The focal length of 800mm, which is shorter than the aperture of 200mm, suggests that this telescope was born for photography.
Going back and forth between the observatory sites in Yangpyeong and Hongcheon, I mentioned what work was needed to optimize this telescope.
The video was made with a focus on how to suppress coma, which is the biggest drawback of Newtonian reflecting telescopes.
I hope this helps even a little bit.
