Thanks Guys,
No doubt the ASA will be an awesome scope its the collimating that puts me off...this is going to be so critical with this scope.
Anyone that does color ccd imaging with a monochrome chip will know if you have to take off the camera to collimate means you will have to take all your flats for every color chanel again plus Luminance and HA if used...yes this can be done but its just something else that has to be done to an already long process.
I think the faint fussies are better imaged at a dark site.
Still thinking.
Also I am not really sure I will get the benifit of such a fast scope in the suburbs of Brisbane.
I would be lucky to get 120 sec exposures.
