Frequently Asked Questions (FAQs)

1. What filters to use on telescope?

There are four main filter types that can enhance your views: solar, lunar, planetary, deep sky. More equipment advice: Telescope stats explained. A basic guide to telescope mounts.

2. Do telescope light pollution filters work?

Many astrophotographers don't realize that light pollution filters do much more than just block light pollution. Using any kind of narrowband filter, including multi-narrowband, can reduce star bloat and greatly enhance the overall contrast of nebulae in your images — even under dark skies.

3. Is moon filter necessary for telescope?

You do not need a filter to look at the Moon. It is safe for your eyes to observe it without one, even during a full moon when it's at its brightest. That being said, there are times when using a filter can improve your viewing experience and give you more detail in the image.

4. Do you need filters for telescope?

Telescope filters can really help you to see more objects and their spectacular details. Basically, you need to ensure you have three important elements when viewing the sky's treasures. These are contrast, sharpness, and how much light you have at your disposal to see the celestial objects.
