The Sirius 2 inch UHC Skyglow Broadband CLS Filter effectively reduces light pollution, enhancing contrast and detail when observing or imaging deep-sky objects from urban and suburban locations. Designed to fit standard 2-inch eyepieces and accessories, this broadband filter selectively blocks artificial light while transmitting key nebula and star wavelengths for clearer, more vibrant views of the night sky.

The Sirius Optics No. 11 Yellow-Green Filter enhances planetary views by boosting contrast on Jupiter's belt details, darkening the Maria on Mars, and accentuating Saturn's Cassini Division. Crafted from dyed-in-the-mass optical glass for premium clarity, this 1.25-inch filter threads easily into standard eyepiece barrels and can be stacked with other filters for selective color filtration.

• Fits 1.25" eyepieces

Enhances:

• Clouds and atmospheric features of Venus

The Sirius Optics Colour Filter No. 12 Yellow (1.25") is a must-have for Mars observers, enhancing contrast between blue-green surface features and orange desert regions. It sharpens the visibility of dust clouds, canal markings, and atmospheric details, making it a favourite filter for exploring the red planet through your telescope.

The Sirius Optics #82A Light Blue 1.25" filter enhances areas of low contrast on planetary and lunar surfaces without significantly reducing overall brightness. Ideal for observing the Moon, Mars, Jupiter, and Saturn, this filter brings out subtle surface details that might otherwise go unnoticed, making it a versatile and popular choice for amateur astronomers.
