Bring out hidden mists<\/h3>\n\n\n\n

The Skywatcher OIII gives your nebulae deeper contrast. The filter lets through only the light that matches ionized oxygen. That is exactly the light that many planetary and emission nebulae emit. The rest is blocked out. This allows you to see faint structures that would normally be lost in background light. Your image becomes quieter, sharper and much clearer.<\/p>\n\n\n\n

See more detail with less effort<\/h3>\n\n\n\n

With this filter, you immediately grab more contrast. Your eyes have to search less and details jump into focus faster. Subtle shapes, soft edges and fine threads in a nebula become visible. It feels like your telescope is suddenly looking deeper.<\/p>\n\n\n\n

Ideal for astrophotography<\/h3>\n\n\n\n

For photography, this filter works great with monochrome cameras. Combine it with H-alpha and SII for a complete set. Your photos will get bright textures and clean contrasts. At a glance, you can see patterns that are normally hidden.<\/p>\n\n\n\n

Solidly built and easy to use<\/h3>\n\n\n\n

The 2\u2033 mount fits wide eyepieces and many diagonals. You simply screw the filter into your eyepiece or filter wheel. The aluminum housing feels solid and protects the coating. This keeps your image bright and clean.<\/p>\n\n\n\n
