3nm and at 396

especially for astrophotography with short focal length lenses

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

this is out of our control

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

ANTLIA 3nm PRO ULTRA NARROWBAND SET Ha + OIII + SII Barlow 3nm and at 396The 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
