stray light

[Adrian-H]

i just want to say that i have filled all the light gaps around the focuser and mirror cell of my dob, and it really has improved its performance, filling the light gaps in your scope isnt hard, and i believe that it is worth the effort to filll in those stray holes.

As the downside of filling in gaps around the mirror cell, you may be blocking air circulation and hindering the cooling of your mirror.
