Light Blue Filter Omegon #82A 2″

Omegon #82A 2″ light blue filter

Color filters are among the most affordable yet highly effective accessories for any visual observer. The Omegon #82A light blue filter is a classic aid for observing planets and other details within the solar system. If you are looking for a reliable and budget-friendly filter for everyday visual work at the eyepiece, this is exactly the right choice.

What does the #82A filter do?

The #82A filter transmits light blue wavelengths while gently suppressing the red and orange components of light. In practice, this means better contrast during planetary sessions:

• Mars - polar ice caps and atmospheric structures become more defined
• Jupiter - cloud bands and atmospheric features are easier to distinguish
• Saturn - atmospheric details appear sharper and better resolved

This is a very subtle filter - it does not cause significant darkening of the image. As a result, it is suitable for smaller telescopes with an aperture of approximately 60 mm and above, making it an excellent entry point into the world of optical filtration without requiring a large investment.

Intended use

The Omegon #82A is designed exclusively for visual observation. It is not optimized for:

• astrophotography
• light pollution suppression
• nebula or supernova remnant observation

Its strength lies in its simplicity and the immediate benefit it delivers during planetary sessions at the eyepiece.

Build quality and compatibility

The Omegon #82A 2″ filter is mounted in a robust aluminum cell with a standard 2″ diameter that threads directly into most 2″ eyepieces. The construction follows the Basic series philosophy - with emphasis on functionality and durability for regular field use. The thread is precision-milled, so the filter seats firmly without play and shows no tendency to seize. The overall dimensions conform to the standard 2″ format, making it fully compatible with any standard 2″ focuser.

Who is this filter for?

The #82A filter is well suited for:

• beginners who are just discovering the world of telescope filtration
• experienced visual observers looking for a simple and reliable color filter for their basic kit
• anyone who regularly observes Mars, Jupiter or Saturn and wants to extract a little more contrast and detail without complex adjustments

Thanks to the gentle transmission of the light blue tint, the filter is kind to image brightness and does not unnecessarily compromise dark adaptation of the eye.

Technical specifications

Summary

The Omegon #82A is one of those filters you slide into your eyepiece case once and reach for again and again - reliably, without surprises, and with consistent results session after session.
