The LS50C offers more aperture for brighter views and finer detail, using the same center-supported etalon design as the LS40F. At 50mm, the increased light grasp enhances both visual observing and imaging potential while maintaining a <0.65 angstrom bandpass.

Tilt tuning keeps operation straightforward—angle the housing to center the H-alpha line and you're observing. No pressure systems, no external controls.

The LS50C includes a B600 blocking filter (6mm clear aperture, for focal lengths up to 540mm) and a custom adapter plate. Provide your objective cell diameter at checkout and we'll machine the adapter to fit—at no additional cost for objective housings up to 4 inches.

Remove the system in seconds to return your refractor to nighttime duty.

Technical Note: This system is designed with a center-mounted foot to support the etalon. Consequently, the filter is center-obstructed.   

Specifications:

• 50mm etalon with center-supported design (Note: Filter is center-obstructed)
• <0.65 angstrom bandpass (H-alpha, 656.28nm)
• Tilt-tuned wavelength control
• B600 blocking filter included (6mm CA, up to 540mm FL)
  
• Custom adapter plate included (up to 4" objective cells—specify diameter at checkout)
• Visual and imaging capable
