Red Color Filter 2 inch – Omegon #25
This red 2-inch color filter from Omegon is ideal for observing subtle details on Mars and other planets. By filtering shorter wavelengths, the image becomes more contrastive, revealing structures that would normally be lost. This filter is particularly effective for observing Mars: polar caps, dust storms, and dark surface features stand out.
For Jupiter and Saturn, this filter can help enhance shadows and atmospheric details. It also reduces bright moonlight, making fine details in craters more visible.

The housing is made of sturdy anodized aluminum with a slim 5mm profile, allowing easy use in a star diagonal or filter wheel. The filter glass is completely homogeneous and features double threading for easy combination with other filters. Comes in a sturdy protective case for safe transport and storage.
