Introduction
Alpy is a family of modular elements for astronom-
ical spectroscopy. The Alpy calibration module allows
you to take quickly and simply, flat field and wave-
length calibration images, manually or even remotely
1
.
It also can be used to make offset and dark images, us-
ing a screen that blocks the light from the telescope.
Equipment configuration
The Alpy calibration module is specifically dedicated
to the Alpy 600 spectroscope, and is optimized for use
in combination with the Alpy guiding module. The
Alpy calibration module can be used in various con-
figurations, but we cannot doccument all of them !
In this document, we consider that you have an Alpy
600 and the Alpy guiding module and you’re already
familiar with this instrument.
You will find in the next chapters a presentation of
the Alpy calibration module, how to install & tune it
on the Alpy 600 and how to observe with it.
Astronomical spectroscopy is a never ending story.
We’ve thought about a lot of applications for the Alpy
instrument (you can find some ideas on the Shelyak
Instruments website
2
). However, we know that you’ll
invent new ones. We’ll be very happy to take your
experiences into account to continuously improve this
product : do not hesitate to contact us if you have any
comments !
We invite you to join the growing Shelyak Instru-
ments users and amateur spectroscopist community
on the Spectro-L Yahoo group
3
and the Aras forum
4
to share your own experiences and ask questions to
the community. We are really interested to see your
results there.
Enjoy Spectroscopy !
