Yes Rich, that is very true ! I did do it with the Orion 102 MCT when I owned one in the past - with disastrous results ! ... It's really not easy to collimate a Mak even with all the instructions laid down from A-Z. You need to turn each screw with respect to the others (usually, there are a total of 6 screws). You really need lots of patience for the task.Hi Weixing,
That's interesting. Disadvantage I suppose of having the screws too accessible is people may eventually be tempted to push the collimation a little more closer to perfection , with disastrous results.

Heard that Mr Aw recently(actually quite long ago..), collimated carole's C90..He said it was so good that he could pump it to 1000X!!!!!
I was curious, when the design of MC came up, what was the original intention? To make it a scope design that didnt require collimation, or was it later when the manufacturers decide so?
Any reknown MCT in observatories?

1000x is venturing into the domain of department store scopes... wat you see will be a big blob of light... heheh
What Mr Au probably meant was that he collimated Carole's scope at 1000x
Anyway, Mr Au is a veteran in Singapore's astrononmy scene, well-known for his interesting talks on astronomy and his passion -- some say fetish -- for collimating scopes.
