Thanks again SF and Bojan,
SF: in the wet season, it rarely gets below 21 with a high dew point and high humidity, in the dry gets down to about 12, low due point and low humidity.
The entire Secondary housing rotates, so the orientation of the 3 collimating screws changes/rotates. Theres a lot of info and misinformation out there, and im not sure if this matters more than just having to recollimate. Some info out there suggests that the secondary must line up exactly as from factory for optimal performance, others say that this applies to the corrector only etc. Not sure where the truth in all this lies. Hence my post, enquiring about any actual experiences.
BJ: is windex available in Oz? Ive been using distilled water and isopropyl alcohol for the exterior of the corrector, but wasn't sure if it would get rid of mould/fungus.
Thanks again
Hemi
