I read it as selling the Dob was a mistake.

I've owned an 8" Discovery Dob and sold it. Biggest mistake of my
astro-life. I have found that both 8" SCT optics and 8" Discovery (Dob)
Optics to be quite good.

However, I have found that Dobs tend to give brighter images due to fewer
optical surfaces (i.e. no diagonal mirror and no corrector plate as in an
SCT). Plus Dobs have smaller secondary mirrors (which is of lessor impact).

Many in this group will disagree with me, however.



So Jim why was the dob a mistake?
