USE
* Professional
Astronomers routinely use the power of spectroscopy to reveal the secrets
of the universe. Now the STAR ANALYSER can do the same for the
amateur imager at an affordable price with this simple telescope attachment.
* Used
like a conventional 1.25 inch filter, it is the ideal accessory for
today's low cost astronomical imaging cameras, webcams and video cameras.
* For
example, with a telescope of just 80mm aperture and
a simple unmodified webcam, the hidden characteristics
of hundreds of stars down to magnitude +4 can be revealed.
With a 200mm aperture and a sensitive long exposure
CCD imager, the identification of bright Novae and
Supernovae or even a measurement of the expansion of
the universe from the redshift of a Quasar are possible.
FEATURES
* High quality transmission diffraction grating mounted in a standard 1.25 inch filter cell
* Anti- reflection coated glass protects the grating surface
* High efficiency 100 lines/mm blazed design
* Simple to use - Screws into a camera eyepiece adapter like a normal filter
* Spectrum direction marked on the filter cell. A locking ring maintains the orientation
* Optimised for the small CCD sensors found in popular webcams, video and astro cameras.
* Star and spectrum can be recorded in the same image, which aids identification and calibration
* Grating distance can be adjusted if desired using spacer rings (purchased separately)
* Can also be fitted to an eyepiece for visual use
