Burgess 127?

(Jon Isaacs) wrote in message ...
I have seen a couple of these Burgess 127 mm F-8 Achromats on Astromart.
The owners rave about the lack of color.
Has anyone out there used this
scope?

I have been waiting for almost a year for the Burgess Optical 102mm F6 scope
and have been following the Burgess Optical forum on Astromart.

This is my take:


(I suggest reading the astromart forum for Burgess Optical. It is essentially
open and unmoderated.)

Nobody is claiming color free performance. Some people were hoping for such a
miracle but these are just decent quality scopes, a cut above the Synta scopes
mechanically and optically they are collimated and adjusted.

Consider this: If these scopes were color free or had significantly less color
than other similar scopes, people wouldn't be selling them for $300.

Statements like "minimal color" are just nice ways of saying that the scope is
not color free, that there is observable false color.

Part of the mystic of the scopes being color free came when the original
prototypes of the 102F6 showed less color than expected. Then it was
discovered that one of the baffles was reducing the effective aperture to
around 80mm so that rather than being an 102mm F6 scope it was actually an 8mm
F7.5 scope with the reduced color as expected.

Huh! More slimy tactics by purveyors of cheap scopes trying to make them
out to be more than they are. Will it never end?

These scopes just recently were shipped, the first ones were shipped sometime
in November I believe. These were the first ones and went to customers on a
waiting list.

Given that over 100 scopes were shipped in the last month or so, 5 or 6 showing
up on astromart seems normal. I do believe at least one of the sellers had
unrealistic expectations for the scope as evidenced by his statements in the
forum. Some probably are probably selling their scopes because their have
changed since they order them in March.

For me, I am expecting a scope that is nicer mechanically than the Orion 100mm
F6 scope and has a good quality achromatic objective. I think my expectations
are realistic, no miracles here, just a decent scope at a nice price after a
long wait.

Thats my take....

Steve it' not just about color. The D&G is a custom made objective, the uses
better quality glass, individually corrected for zones, astigmatism as well
as color. Even if they were the same focal length, the D&G would be better.
The Burgess (same factory as the Meade) is 100% machine made. In terms of
the total quality of the image, it isn't close. The Burgess compares to the
Meade and Synta scopes- Orion, Konus and Celestron. The D&G compares to
Vixen, Stellarvue and Televue. The Burgess costs the same as the Orion,
Celestron and Meade OTAs, the D&G costs the same as the Vixen, Stellarvue
and Televue.

Seems they are very inexpensive.
