Cheers all for the replies.
Thanks Paul for the advice and pics on the reg marks.
I'm aware of the requirement to return everything back into it's correct placement and alignment but tbh had only considered maybe 2 marks. I do really like your approach and will use that even if I only end up simply cleaning the corrector.
That is the questions I'm asking really.
from the site I added in the original post they state
"I've flocked a C5 and put it up against an unflocked C8 on deep sky objects, and the flocked C5 shows more contrast and nebulosity extent, cleaner images on bright objects, and more resolution on globulars. I think flocking has the effect of improving an SCT by two magnitudes of light grasp. How can this be? Optical authorities will tell you that an SCT system looses
about 30% of its light grasp in internal reflections and loss of contrast. Flocking is the easiest way to solve this problem."
even Alex's comment of 'I must say the difference was MILDLY noticable'
suggests that it maybe worth the effort considering I'm already in there.
I'd be cool with mildly noticeable .
If it was just to perform this job then I wouldn't be considering it.
While I like to pull stuff apart just to see how it works I'm the sort that usually ends up with a few spare bits at the end of the job and am asking myself where THESE come from
I'd prefer not to pull the whole assembly apart if I could avoid it.
Maybe I could just flock the upper OT and secondary assemblies as a compromise.
Oh and if anyone can still suggest where to get the allen keys for the job or size of the bolts holding the retainer ring from the corrector plate that would be brilliant.
