Thank you liking my #Telescope Mount Controller using PERSEUS-9! Astronomy and computers have been my hobbies for over 40 years. This time I have combined both of them to create something of a practical level in my own way.

  Are you sure? yes | no

KJoh wrote 02/05/2024 at 20:13 • point

Yes, I have a budding interest in automating telescope mounts, while at the same time having great admiration for your beautiful project enclosures (in this and your other projects).  Best regards,

Ken

  Are you sure? yes | no

Mitsuru Yamada wrote 02/06/2024 at 06:11 • point

Thank you. I always try to design enclosures that will still be usable more than 10 years from now.

  Are you sure? yes | no
