SVBONY SV132 1.25 H-Beta 25nm Light Pollution Filter (W9102A) For Discount

Description
SVBONY SV132 1.25 H-Beta 25nm Light Pollution Filter
- SV132 H-Beta eyepiece filter makes it possible to view the elusive Horsehead, California, and Cocoon Nebulas in dark skies;Great used with a moderate to large aperture telescope and clear dark skies
-
- Optical high precision double side polishing; Filter substrate is fine-optically polished to 1 4 wave and <30 parallelism over both surfaces; Avoid halos
-
- Precision double-sided optical coatings improve transmission and cut-off depth; Executes with a transmission of over 90% and completely rejects light pollution
-
- High value transmission of pass-band and optical density of off-band is assured through planetary rotation system, a homogenous and precise coating procedure; The high optical quality of SV132 filters guarantees no loss in sharpness or contrast
-
- Filter with metal mount 1.25 filter threads; Threaded to fit 1.25 eyepieces and threaded diagonal barrels
-

1. Each Svbony filter has an ultra hard, vacuum-deposited coating carefully designed to observe the Orion Horsehead Nebula and the California Nebula, which are difficult to capture. This eliminates the un-natural colored halos surrounding bright stars common with H-Beta filters of less sophisticated coating technology
2. The 1.25 Svbony H-Beta filters suitable for viewing bright nebulae, and matching with large-aperture telescopes to observe linear spectrum nebulae,such as the M42 Orion Nebula under severe light pollution, emission nebulae, planetary stars & supernova remnants
3. Suitable for viewing on the faint and elusive Horsehead Nebula and California Nebula
