Thanks heaps guys, back to square one. I was observing Jupiter near zenith last night so I'll try realigning the secondary and recollimating, with an attempt at star collimation, if no success then rinsing the mirror.
I must say that I wasn't that impressed with the outcome of my mirror cleaning as the primary doesn't look like a super polished mirror. When viewed from a side angle, it has a fine, uniform patterning\smudging all over, perhaps from living very close to the ocean. Though looking into the mirror, my reflection is very clear. The secondary isn't flash either.
What would the effect be if the secondary was slightly pinched from over tightening the retaining bracket? Could this also cause some flaring?
Cheers
Simon
