While I’m at it, I think I will dismantle the OTA, and spray paint a few things black and carefully paint the sides of the mirrors. There are some great YouTube videos out there on enhancing Newtonians. Any recommendations on a matte black spray & matte black paint? Thanks.
I’d be careful painting the mirrors and to be honest I don’t think you need to , there’s more important things you need to address before painting sides of mirrors IMO
When I take flats and bias calibration frames I just fit a shower cap ( outside sprayed black) over the end of the OTA to eliminate light leakage
I’m leaving my mirrors alone ( just a clean every year )

Yes, I used 2 bolts to secure the mini bracket that holds the guide scope tube rings
Everything has to be solidly fixed especially when using guide scope assemblies for focal lengths of 1000mm and up to 1500mm , beyond 1500mm fl it’s best to use an OAG which has its own set up and running issues too.

Cheers
Martin
