Rich cretins have just as much collimation issues as newtownions though maybe?

At least the image train  is somewhere sensible

Believe me they are more difficult than Newtonians. The RC is even more difficult than the CC due to the distance between the primary and secondary mirror being crucial and not easy to measure.

Learning to collimate at F4 will be the least of your AP problems.      🙂

Too right there Peter🤬

Yeah there are horror stories,and  a 103mm refractor is collimation free , and because of the large secondary with f4 Newtonian a 103mm will have similar light gathering power. But I think a lot of the negative side with this particular scope ( I think I know the one you mean) can be delt with by the upgrades available, particularly the secondary mounting which makes collimation less of a problem. Having said all this I'm ordering the 150 Quattro 🤗
