Easy To Use Altair Ultra 3nm Oiii Narrowband Filter 2" Certified Easy Returns [7dfY6pDz]

Altair ULTRA 3nm Oiii Narrowband Filter

The Altair ULTRA 3nm Oiii Narrowband Filter is a cutting-edge accessory designed for astro imaging enthusiasts. This filter is specifically crafted for Mono CCD or CMOS cameras, making it an ideal choice for capturing stunning images of nebulae. Its core feature lies in its ability to block light pollution by eliminating unwanted wavelengths, resulting in crystal-clear images with exceptional contrast. The filter boasts a 3nm FHWM, offering higher contrast compared to broader filters, making it perfect for heavily light-polluted urban areas.

• 3nm FHWM for enhanced contrast in urban settings.
• AR Coating to suppress halos and internal reflections.

Technical Specifications and Benefits

The Altair Astro 3nm ULTRA filters are engineered with precision and care. Each filter comes with an individual spectrographic report, ensuring that it meets the highest standards of quality and performance. The filter features OD4 blocking in visual wavelengths, providing ultra-high contrast for observing faint objects. Its advanced UV/IR blocking coatings help maintain small star sizes, even with refractor optics. The ultra-flat BK7 glass and precision CNC machined filter cell ensure strain-free mounting and freedom from tilt. Key specifications include a 1.85mm thickness, 1/4 wave flatness, and 30 arc seconds parallelism.

• Individual Spectrographic Report for guaranteed performance.
• OD4 Blocking for ultra-high contrast.

Practical Applications and Target Audience

Whether you're an amateur astronomer or a professional astrophotographer, the Altair ULTRA 3nm Oiii Narrowband Filter is a valuable tool for your equipment arsenal. Its ability to suppress artificial lighting and skyglow allows for long exposures in urban conditions, making it perfect for capturing detailed images of celestial objects. The filter is designed to work best with optics slower than F4.8, although it can still be used with faster optics at the cost of some contrast. Ideal for use with F6 or F7 refractors with reducers, this filter is a must-have for anyone looking to enhance their astro imaging experience.

• Optimized for Urban Astro Imaging with long exposure capabilities.
• Perfect for Amateur and Professional Astrophotographers alike.
