ZWO Duo-Band Filter 2 inch: Deep-sky photography in urban areas<\/strong><\/h2>\n\n\n\n

Do you use a color camera and want to capture emission nebulae without switching to a monochrome camera with a filter wheel? This 2-inch dual-band filter combines the H-alpha and OIII emission lines into a single filter. It blocks all other light, including street lighting and moonlight, allowing nebulae to be imaged with significantly higher contrast, even under moderate skies.<\/p>\n\n\n\n

The filter is tailored for ZWO ASI color cameras such as the ASI294MC Pro and ASI2600MC Pro. Owners of the ZWO Seestar S50 can also use this filter: with the Omegon Dust and Dew Shield plus the Omegon M62 to M48 adapter, you can mount this 2-inch filter in front of the lens of your smart telescope.<\/p>\n\n\n\n
