Btw, what focal ratio is your scope? That could have quite an impact on how bright the image is looking, relative to what you might be seeing (and expecting) from other peoples' posts. Some folk are using f/4 and f/5 scopes which would be noticeably brighter. Just trying to set your expectations  |
Sorry to be too-ing and fro-ing between the two threads. the focal ratio is 7.5, aperture 120mm. I was considering getting a focal reducer, but I'm still looking at the implications of that.
