Sky and Telescope - April 2015 - 7

ONE HALF OF THIS
IMAGE WAS TAKEN
WITH A $2,499 ESPRIT

THE OTHER WAS TAKEN
WITH A SCOPE THAT
COST TWICE AS MUCH
Actually, the other telescope cost more than
twice as much as the Esprit, but that's not
really the point. The point is, do you see twice
as much performance on one side of the
page than the other? Take a close look.
Are the stars twice as pinpoint?
Is the color doubly corrected?

We don't think so.

Esprit triplet. At Sky-Watcher USA we pride
ourselves on offering products with worldclass performance at affordable prices.
Because we know there are other things you
could be spending that money on.
Like a mount. Or a camera.
Or even a really, really sweet monster

The Sky-Watcher line of
Esprit ED Apo triplets.
All of the performance,
half the price.

Starting at only $ 1,649, the Esprit line is offered in 80, 100, 120 and 150mm
