Noted. My experience is that even Gregory Maks have better contrast than SCTs.Bigzmey wrote: ↑Thu Jan 09, 2020 10:38 pmBad sampling can go both ways. I have not, but would love to try better executed Maks. As for mass produced Gregory Maks, they are not bad. I still prefer SCTs though.notFritzArgelander wrote: ↑Thu Jan 09, 2020 9:42 pmBad sample?
I MUCH prefer aplanatic SCTs and Rutten Maks and Klevzov Maks for DSOs and planets. Even Gregory Maks like this Bresser model outperform standard SCTs on lunar/planetary.
Apart from sampling issues there are individual physiological differences and differences in experience of the observers.
I'm very much put off by field curvature aberrations and loss of contrast. Having had a lot of experience with 8" SCTs I had high hopes for the 9.25 SCT "the SCT for folks who hate SCTs" as Ed Ting says if I recall right. It was a disappointment and lived down to my experience of the 8" SCTs. Now the aplanatic Edge 9.25 was wonderful!
I'm looking at a 9.25 or 11 Edge or a VMC260L as my last non feline CAT.
