resolution vs seeing in large aperture RCs
Hi all, i have just been thinking about some of the larger RCs that are becoming popular, particularly now that GSO have entered in the game. in particular i am looking at a comparison between the planewave CDK 12.5 and the CDK 14. given that these scopes have virtually the same FL, the only difference is a small f ratio (7.2 compared with 8) and the extra 1.5 inches of aperture. when it gets to these types of aperture sizes, are you really getting any better practical resolution out of it? unless you are on top of a mountain and can remove a large portion of the atmosphere.38' of resolution is surely going to be more than the atmosphere will allow. so is resolution not really a factor in these scopes? or is the larger aperture really for allowing less time in gathering data and better ability to pick up faint nebulosity? interested to have the thoughts those with more experience than me.
