I think you can start showing the 12.5" PDHQ from Discovery the door
as well. $1299 for .5" additional aperature , no encoders, and no
finder....CYA! BTW, I am 15 hours from completly rebuilding my
Discovery 13.1" web special. Its purrty....(thats for you Rod ;-))


Discovery makes some nice scopes. I think the advantage that the Asians have
is that the 12 inch OTA's are more manageable, 56 inches or so in length
instead of 64inches and 48-50 lbs for the OTA instead of 60+ lbs.

As a bonus it includes those nicely figured mirrors that turn a lot of people
into refractor fans.

Hi:

I'm not sure what you're referring to. Guan Sheng and Synta mirrors? The scopes
may have their weak points, but the mirror figures are NOT one of them...and I
ain't exactly a Newtonian fan, pard. ;-)

Peace,

Rod, I am a newt fan, and a fan of any other properly executed telescope. I
have owned my share of mass produced newts. Out of the ten or so mass produced
newts I have owned one gave razor sharp planetary images. The others gave soft
images. I have owned some good newts with custom mirrors they are a horse of a
different color.

Why do you think the following paraphrase is so common, " My 4" APO blows away
my 6,8, 10 inch newt on planets?"

I have compared several APO's to several newts. Almost without fail the 4" APO
gave better images of Jupiter than the mass produced newt. The only exception
was a really good 8" F6 Meade EQ Starfinder I owned, and an 8" F6 Celestron
Starhopper that belonged to someone else. The custom made newts without fail
out performed the smaller APO's on Jupiter. The 6" F5 I own now is a tad
better on Jupiter than the 4" APO's I have owned. The 4 mass produced 6" F8
scopes were not. Go figure.

Not nice! g

Actually the Orion and similar Chinese/Taiwanese Dobs seem well regarded.
