The CFW-9 system is designed to be "Direct connected" to any ST-7/8/9/10/2000 imaging camera for a thinner, more rigid mounting.

SBIG also furnishes precision UBVRI filter sets with the Model CFW-9, filters that allow the user to perform color photometry to measure the classification and temperature of objects.

They selectively increase the contrast between markings of different hues and reduce "irradiation," the smudging of boundaries between light and dark regions that results primarily from turbulence in the Earth's atmosphere. Indistinct features suddenly become distinct! Perfect for astrophotography. Orion color telescope filters are made from high-grade Schott optical glass and vat-dyed for even color coating, and then given an anti-reflection coating. Their anodized aluminum cells are double-threaded to permit filter stacking and are labeled with their Wratten filter number. Available in 1.25" and 2" sizes.
