Wow, I didn't expect anyone to reply so quickly. Thank you Franklin and Froeng.
Actually my father bought me the telescope about 37 years ago when I was 13 and was living in Japan.
Back then I think the whole set costed 1,000 USD. I kept it for long time and planning to bring the telescope to Japan after Covid for overhaul as it has so much memories in it.
The Saturn mount is still there but together with the stand its extremely heavy and its now quite rusted and after being decades away from astronomy I forgot how to find stars and etc, so
I thought I might just as well get one of the go to mounts with GPS and start star gazing again this time with my son.
@Froeng I checked out the AXJ and SXP2 on the Japanese website, but the price is super expensive, I will try to look for a used one in the Japanese auction sites, also I found out the just recently that my telescope is one of the good ones made back then.
I will definitely require more advice as I want to get back into the hobby, so if you both don't mind I will ask for further advice.
With the digital DSLR cameras, taking photos of stars should be much easier than 30 years ago.
Thank you for the response
