GSO manufactured 10" dobsonian telescope cover mod

This is a mod to the cover of 10" Dobsonian telescope models produced by GSO. Brands include:

Apertura ( usa )

Starfield ( Canada )

StellaLyra ( uk )

and others

I made these tabs that can be glued onto the side of the cover, which stop the cover from falling into the tube and potentially causing collimation issues with the secondary mirror assembly or spider.
