BAADER SLOAN/SDSS G' PHOTOMETRIC FILTER Size:2" The TS Optics 2

The TS Optics 2

Combining the reflecting and double refracting action (the incoming light passes through the full thickness of the primary mirror twice) of this element

These German-made and ISO/CE-certified glasses are perfect for watching the partial phase of solar eclipses or sunspot clusters

1200mm x 1600mm

and its loading capacity allows for mounting instruments like 200mm diameter refractors

BAADER SLOAN/SDSS G' PHOTOMETRIC FILTER Size:2" The TS Optics 2The Baader SLOAN g' filter is a precision grade photometric bandpass filter with a central wavelength window around 468. 6nm. In 2000, a new era in photometry began: with the Sloan Digital Sky Survey (SDSS), a 2. 5m telescope at Apache Point Observatory (New Mexico, USA) surveyed one third of the sky in five wavelengths, with windows around 355. 1, 468. 6, 616. 6, 748. 0 and 893. 2 nm. This system was also used for the Pan STARRS project; the broad
