Product description Compared to the Lumicon #23A Light Red filter, this Lumicon #25 Red 2" Filter darkens the reds even more near the yellow tones in the spectrum, as its transparency only begins in the orange-red region. It produces dramatic effects and extreme tonal separation for graphic effects. For planetary observing, color filters bring out the most detail because planets are naturally colorful. Different colors bring out different details of the planet you are viewing. Always remember that you want to use the darkest filter your telescope will handle. Most small telescopes up to about 5" in aperture use the light colors. The larger the telescope, the darker your filter you can use. Color filters can sometimes be used in conjunction with a Neutral Density or Polarizing filter to aid in glare reduction. The more you use your filters the more you appreciate them and their affect. The 1.25" filters employ industry-standard 1.125" x 42 tpi threads (except for Questar/Brandon, which use a thread pattern unique to Questar). The 48 mm filters employ industry-standard 48 x 0.75 mm threading, which thread into 2" eyepieces. All larger filters use the given size with 0.75 mm pitch (e.g. a 72 mm Minus Violet filter has 72 x 0.75 mm threads).
- Stronger than an Light Red (23A)
- Clouds are dramatically improved almost to the mood of a thunderstorm; Darkens blue sky creating dramatic contrast between sky and clouds
- Use with Polarizer for dramatic black and white effects
- It is more effective in cutting through haze, and moonlight effects are easily accomplished
- Used in scientific photography
