Your photos bring back fond memories of the Carton 60mm scope that I owned for many years.
I eventually brought an ED80mm (F7.5) scope and it was a major improvement. The 80mm scope simply has more light grasp, greater resolution and no CA. From memory, the carton was only usable to about 60x and showed annoying CA at that magnification.
The 80mm may be larger, but is still easily mounted on a variety of mounts. I would suggest buying a Skywatcher AZ4 for it.
