Baader Semi-APO 1.25" – Color correction & contrast boost

Long description:

The Baader Semi-APO 1.25" filter is designed for achromatic refractors, combining the effects of the Neodymium Moon & Skyglow filter and a reinforced Fringe Killer. This advanced combination delivers high-contrast, color-neutral images without the internal reflections caused by stacking two separate filters.

It efficiently eliminates blue and red halos (violet fringing), offering significantly cleaner and sharper planetary and lunar views. Thanks to its built-in IR-blocking coating, it also works well for astrophotography, especially with CMOS or CCD cameras lacking an integrated IR-cut filter.

With high optical quality and zero ghosting, this filter is a must-have for visual and imaging applications using small achromatic refractors.

Technical specifications:

• Type: Combined chromatic and skyglow filter

• Diameter: 31.75 mm (1.25")

• Thread: M28.5 x 0.6 mm

• Correction: Removes blue/red halos

• Transmission: Neutral in visible spectrum

• Coating: Multi-layer anti-reflection, IR-block

• Use: Visual and photo

• Compatibility: CMOS, CCD, DSLR

• Weight: approx. 40 g

Additional information:

The Baader Semi-APO is ideal for enhancing the performance of achromatic refractors. It improves sharpness, contrast, and color balance without any reflections or the need for an additional IR-cut filter.
