Descriere produs

Din pacate, descrierea acestui produs nu a fost inca tradusa in limba romana, din acest motiv veti gasi in loc o descriere in limba engleza.

The Optolong SHO-3nm filter kit includes SII 3nm, H-Alpha 3nm, and OIII 3nm narrow band filters, generally working with astronomical monochrome cooling CCD and modified DSLR imaging in each single-channel. Corresponding with RGB channel (HA, OIII, SII), photographers can process Hubble images by astronomical post processing software.

Extra narrowband SII CCD 3nm filter is designed for nebula observation, allowing 3nm bandwidth of light centered on a wavelength of 672nm and reducing the transmission of certain wavelengths of light, specifically those produced by artificial light including mercury vapor, and both high and low pressure sodium vapor lights and the unwanted natural light caused by neutral oxygen emission in our atmosphere (i.e. sky glow).

H-Alpha 3nm filter is the popular narrowband filter, allowing 3nm bandwidth of light centered on a wavelength of 656nm and reducing the transmission of certain wavelengths of light, specifically those produced by artificial light including mercury vapor, and both high and low pressure vapor lights and unwanted natural light caused by neutral oxygen emission in our atmosphere (i.e.sky glow). A better choice of narrowband H-Alpha astrophotography filters for highest contrast and revealing subtle nebula details.

Extra narrowband OIII-CCD 3nm filter is designed for nebula observation, allowing 3nm bandwidth of light centered on a wavelength of 500nm, which corresponds to OIII emission line, and reducing the transmission of certain wavelengths of light, specifically those produced by artificial light including mercury vapor, and both high and low pressure sodium vapor lights and the unwanted natural light caused by neutral oxygen emission in our atmosphere (i.e.sky glow).

OIII emits 495.9nm and 500.7nm and it is a blue-green colored filter. Many images of planetary nebula and supernova remnants are taken only with H-Alpha and OIIII filters. They show great structural details, but have natural colors, looking like an RGB image.

Features of the SHO kit:

  • give you higher contrast and greater detailed views
  • decrease background noise and improve the contrast of objects
  • increase the faint nebula signals and make them brighter
  • with a narrowband fitler kit you are able to process a hubble image
  • optimization of the sustrate and upgraded coating technology
