G'day darkskybondi
It's a dob what did you expect
there's a 20" inch out on the back mountain here collecting dust and webs
to much of a hassle getting a tall 4mt ladder in the dark and shifting it
I prefer to keep my feet grounded with the 12" SCT
As for DIM 8" should be plenty BRIGHT
maybe dewing up ? that used to creep up on me
