I too read Peter Manlys book (20cm SCT). I enjoyed reading it. If I =
remember correctly, he made a two line remark about the mirrors image =
as being a trade-off. Its on page 182-83 (mirror flop).=20
I would have to agree with the suggestion that more mechanical diagrams =
be included with the book. To see the focuser in a diagram would be =
very interesting. =20
Finally, I think Manly did a fine job incorporating basic astronomy =
with the 8 inch abilities. This gives the beginner a chance at planning =
little projects to undertake with the scope. After all, we cant spend =
all of our nights taking photos or dreaming of a comet named after =
ourselves, though we may like to.
Its a fine book and worth reading, especially for the novice.

I agree,
I purchased the book in the hope I would be getting a good telescope =

for my cousin who has just received a new SCT. It is a good book but =
the=20
title is a little bit deceiving.

Im a beginner who just read this book. While I learned a great deal, I
couldnt help but notice that focus shift (or image shift or whatever =
the
term is) is never even mentioned. This seems like a major omission to =
me. I
was also disappinted that there were no diagrams of the inner guts of =
the
thing, only many different drawings of the light path. Id like to see =
how
the focus knob moves the primary, and maybe a picture of a worm gear
assembly. On the whole, Im glad I bought the book, but I think it could
concentrate more on SCTs in particular and less on basic astronomy. =
Thanks!
