Labouring this point.. so an 8" mirror can only ever give the same resolution, regardless of whether it's an f4 newt, or an f8 RC, or an f10 SCT, or any of the above with reducers or paracorrs?
The magnified result (determined by the f ratio) will only just increase the size (much like an eyepiece does) without providing any more or any less detail, so it wouldn't benefit me to look at any other 8" scope & expect more detail (unless I've been incorrectly sampling but with 3.8 micron pixels (around 1 arcsec/pixel) i think there's not much to be gained by going with smaller pixels) so i could consider the case closed.
Thanks all
