Extra narrowband SII-CCD 6.5nm filter (Sulful II for CCD) is designed for nebula observation allowing 6.5nm bandwidth of light centered on a wavelength of 672nm through, 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. skyglow).

Extra Narrowband OIII-CCD 6.5nm filter is designed for nebula observation allowing 6.5nm bandwidth of light centered on a wavelength of 500nm through, which corresponds to OIII emission lines, 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. skyglow).

• Baader-FlipMirror II Star Diagonal (BFM II) with three ports:
  • Straight-through (S52, M48 and T-2 on both sides) for full-frame camera, spectrograph, or other instruments
  • Adjustable T-2 thread on top for eyepiece clamps, video modules (up to 32 mm image circle) or even a binoviewer
  • Bottom flange for the optional Off Axis Guider for Baader FlipMirror II (BFM-OAG)(#2956951, € 98,-) or for an optional calibration lamp for quick calibration of spectra without removing the spectrograph

The L-Pro Astrophotography CCD filter is a filter for improving the contrast of deep-sky objects and dampening the sky background.

• blocks UV and IR (700 - 1100 nm)
• high transmission at passband
• improved color balance for DSLRs and One-Shot Color Astro Cameras, e.g. ASI Color Cameras cooled or uncooled by ZWO.
• high optical quality
• in 1.25" filter cell
• The L-Pro Nebula filter permits roughly 3x longer exposure times than without a filter and therefore improves contrast significantly.
