Many emission nebulae, such as the North American Nebula, the Rosette Nebula, and the area around Sadr, glow strongly in the hydrogen red line. The Optolong H-alpha 3 nm only shows a narrow band around that line. This keeps a lot of light pollution and moonlight out of your image.<\/p>\n\n\n\n

This 36 mm version is intended for a filter wheel<\/a> with a monochrome camera. If you want all three lines for the Hubble palette immediately, then there is The 3 nm SHO set in 36 mm<\/a>.<\/p>\n\n\n\n

Check that the filter wheel fits this size and that it matches the sensor size of your camera and your optics. Note: This is a filter for neofoto photography and not a sun filter. Make sure you never photograph into the sun with it. That only works with a complete, correct sun filter setup, such as an H-alpha solar telescope from category of solar telescopes<\/a>.<\/p>","protected":false},"excerpt":{"rendered":"
