Always lusting after large MCT, but never buy one
Quote:Well these are all sort of the same in cost. I could add an 8" f/5 Newtonian to the mix. This should be good for wide fields plus all the above but much bulkier than a SCT or MCT.

Quote: I think the helical focuser and lack of range and small CO is a problem for the Intes MN scopes for wide fields and imaging.
Quote:So would you recommend a SCT/MCT/refractor?
Quote:The Russian Mak coatings seem a bit warmer and duller than similar size Newtonian mirrors, anyone else want to chime in?
Quote:A good 8" f/5 Newtonian plus Paracorr is about as good as a MN but cheaper and more aperture.
Quote:Everyone's experience is different and equally valid. But reading back through old reviews of Russisn MCTs or MNs, dim and less sharp are not terms you will see often. The Intes and IM optics are generally considered very, very good--especially the deluxe models.
Quote:If the image is not perfectly sharp, there is an issue somewhere. Whether it is collimation or the scope is not cooled down or the seeing is poor. All of those conditions would effect a Newtonian as well.
I ache, therefore I am
Quote: Also the mirror coatings would be aluminimum (80%) rather than dielectric (99%). This will have a barely perceptible effect on "dimming" of the images, reducing the limiting magnitude by around 0.4 magnitude.
