Filter Chroma Jovian Methane 50 mm, unmounted (SKU: CT-27012-50D)

Chroma Jovian Methane 50 mm filter, unmounted (Chroma, SKU: CT-27012-50D) is a filter for planetary imaging in the near-infrared methane absorption band. Regions containing more methane appear darker in this range, helping distinguish atmospheric structures on giant planets, particularly Jupiter.

Key features

• imaging in the methane absorption band
• enhanced contrast between structures with different methane absorption
• designed for photographic imaging of planetary atmospheres
• durable hard-sputtered coatings on a single glass substrate

Included items

• filter Chroma Jovian Methane 50 mm, unmounted
