It's nice, just don't make sense!Friction moved scopes don't work below a certain mass, i.e., the base will likely shift if you try to use the bearing in the base. Moot anyway, it's more a decoration.

Grotesque extra bulk for nothing. Dob mounts were designed originally for LARGE (10 inch plus) telescopes so they could have a relatively light-weight, low-to-the-ground and inexpensiveHere's a 4.5" DOB! https://www.telescope.com/Orion-SkyQuest-XT45-Classic-Dobsonian-Telescope/p/102009.utsIt's nice, just don't make sense!Friction moved scopes don't work below a certain mass, i.e., the base will likely shift if you try to use the bearing in the base.

mounting. Small scopes should be on fork mounts or equatorials.
