ANTLIA 3nm PRO ULTRA NARROWBAND SET Ha + OIII + SII Barlow Note: Due to the many

Note: Due to the many different dovetail bars on the market and different manufacturers' tolerances

An alt/az mount is inherently more stable than an equatorial mount since there is no cantilevered mass

The Optolong UHC (Ultra High Contrast) broadband filter is designed to improve the visibility of deep sky objects such as emission nebulae and supernova remnants

External Diameter: 90 mm

especially for astrophotography with short focal length lenses

ANTLIA 3nm PRO ULTRA NARROWBAND SET Ha + OIII + SII Barlow Note: Due to the manyThe new Antlia 3nm Ultra Narrowband filters boost the contrast of emission nebulae and supernova remnants for professional results, even under a bright sky affected by light pollution. The 3nm bandpass is only 1% of the entire visible spectrum increasing the signal to noise ratio delivering high contrast images and extremely dark backgrounds. To even further enhance the contrast, and suppress the stray light and internal reflections, Antlia applies
