Description: Description Astronomical telescope 1.25 inch no.21 Orange Nebula filter The nebula filter is used to let you see the nebula more clearly. It should be connected to the back end of the telescope eyepiece for use. Astronomical photography is also very common. You can see the nebula without a nebula filter, but you can see more beautiful with a filter. Of course, there are also some nebulae that can only be seen with filters, which means that filters can let you see more nebulae. Nebula filters are generally narrow-band filters, which means that they can only allow light to pass through a small range of wavelengths. For example, the common Nebula filter is the oiii filter, which can only let a small part of the blue-green light near 5000 angstroms pass through. Because the light emitted by the nebula is concentrated in this frequency band, after doing so, the light emitted by other objects such as stars is weak, while the light emitted by the nebula is much weaker, so the nebula becomes prominent Description Brand: SkyoptikstLens material: optical glassLens color: OrangeFrame material: aluminum alloyThread specification: m28.6*0.6mmInterface size: 1.25 inches (31.7mm)Net weight: 6gGross weight: 17g Payment Terms Payment must be received within 7 business days of auction closing.All our items will be shipped to buyer's payment address.
