KASHIWAのカメラ画像データを元に、JH4XSY/1局の記事を参考に画像化してみた。
かなり無理矢理で、完成画像は大分ずれているが、一応絵にはなったので達成感
はある。SatNOGSからデータをダウンロードし、CAS-5A_jpg化記事を参考にした。
Based on the KASHIWA camera image data, I converted it into a jpg image
with reference to the article by JH4XSY/1. It was quite forced, so the
finished image is a little off, but it turned out to be a painting, so
I feel a sense of accomplishment. I downloaded the data from SatNOGS
and referred to my article on converting it to CAS-5A_jpg.
