focuser and tiertary mirror:

ultralight version, 7 kg. watch out for OSP2023:

 

1 please note that, due to larger secondary mirror(67mm sec) being used,  central obstruction of 32.5%, will be 4.5% bigger than conventional newtonians(56mm sec)

2 how to attach a finder scope, leaves something to be desired. Maybe a smartphone with a star map app can do.
