• Product Type: QUARK Magnesium I b2 line "Eyepiece" for refractors F/4-F/9.
• Visual Appeal: Magnesium's bright green color aligns with the human eye's highest sensitivity for clear visibility.
• Astrophysical Studies: Ideal for studying boundary layers between granulation and spicule, revealing details like plague and Zeeman splitting in magnetized areas.
• All-In-One Design: Combines a telecentric barlow, adapters, snouts, and the MgI b2 line filter into a single assembly, optimized for efficiency and quality.
• Magnesium I b2 Filter Specifications: Central Wavelength (CWL) at 5172.8Å with a Full Width at Half Maximum (FWHM) of <0.5Å.
• Ease of Use: Designed for refractors of F/4 to F/9 without the need for complex configurations. Simply insert in the diagonal, add an eyepiece, and view.
• Advanced Optics: Includes a custom Daystar Instruments 4.2X telecentric barlow lens, ensuring superior field flatness and approximately 0.3-0.5 angstroms bandpass.
