BIG NEWS New CED 1 and 2 Diagonals

Hey Guys

We have waited for months to make this announcement. Well here it is. Burgess
Optical has developed what may prove to be
One of the most innovative products in Astronomy. Its called the CED
diagonal,CED stands for Contrast Enhancement
Diagonal and they will be available in 2 versions. These new diagonals will
boost low level contrast on all objects and the results
range from extremely subtle to very impressive. The CED 1 is for all scopes that
have good to excellent color correction, examples
SCT, MC,APOs?and ED doublets. In addition to contrast gains the?CED 1 will also
improve the visible color correction of the ED
Scopes. The CED 2 is for Achromats and here the results are shocking, Huge
reduction in color or even elimination in CF Achromats
all the while maintaining?ABSOLUTELY NEUTRAL color balance. Contrast Enhancement
is?also quite shocking on the Planets.
Please forget to even try to compare this to a filter NONE WILL DO WHAT THE CED
does and?ALL?DEGRADE your image as light past thru the glass. Guys I could go on
and on but you would not believe Me so?I have sent several out and just wait on
the reports.
Regular production will begin next year BUT I HAVE 100?units NOW available just
to this group. 90 CED 1 and 10 CED 2.?
Prices next year will be?$199,00 but I will make these 100 units available to
this group only for?$169.00. If these diagonal don't
blow your minds?I will refund the $169.00 plus the shipping and give you $20
extra just or your time.


Bill
