Vintage Lumicon 1.25" Deep Sky Telescope Filter (Pre-owned)

The Vintage Lumicon 1.25" Deep Sky Telescope Filter is a specialized filter designed to enhance the viewing of deep-sky objects such as galaxies, nebulae, and star clusters. Here are some characteristics and benefits of this type of filter:

1. Light Pollution Reduction: The Deep Sky filter selectively blocks wavelengths of light associated with artificial lighting and atmospheric pollutants, improving contrast and visibility of faint deep-sky objects from light-polluted locations.

2. Enhanced Nebulae and Galaxy Observation: It helps to enhance the visibility of emission and reflection nebulae, as well as improve the contrast of galaxies against the background sky.

3. Increased Detail and Contrast: By reducing the background sky brightness and enhancing the contrast of celestial objects, the filter can reveal more details within nebulae structures and bring out fainter stars in star clusters.

4. Broadband Transmission: Typically, deep sky filters like those from Lumicon are designed to transmit a broad spectrum of wavelengths while selectively filtering out specific lines of light pollution and atmospheric haze.

5. Compatibility: The 1.25" size indicates that it fits standard 1.25-inch eyepieces, which are commonly used with telescopes. Ensure compatibility with your telescope's focuser and eyepieces before purchasing.

6. Vintage Lumicon Quality: Lumicon has a reputation for producing high-quality astronomical filters. The "vintage" designation may refer to an older model or design of the filter that could still offer excellent performance for deep-sky observation.
