I wonder why not a C-6 ?

Yes, for the highest portability, there is no any good reason not to choose C6...

If money is your hesitancy, paying half an amount or more less of a C6 for a portable newtonian is no doubt another good choice. But traditional design( closed tube) for a 6 inch F4-F6 newtonian is still a bit far from ideal portability, so a retractable design is a good choice for maximum portability. 

Obviously, looking at its price, this Italy-made newtonian is not for money-saving stargazers, even more than a C6. So Instead, I would like to suggest DIY one with your own features. 

Coincidentally, I was recently constructing a similar small newtonian with a commercial 3" mirror, but the focal length is a bit too long(F/10, 750mm). The current design is not retractable, but I will modify it to this design later. For cute design, F4 to F6 is more better, so I am going to find another short focal length. I made this small newtonian solely for collecting more concepts on my future projects. Next targets should be 4", 6" or even bigger....
