If you're looking for a high-quality filter for your astronomy telescope, the OPTOLONG 2" Filter H-Beta 25nm is an excellent choice. This filter has a narrow bandwidth of 25nm, which makes it perfect for deep sky astrophotography and visual observation of nebulae.

The H-Beta 25nm filter allows you to capture stunning images of nebulae with high contrast and minimal light pollution.

This results in stunning images with rich, vibrant colors that are sure to impress.

The filter is made from high-quality optical glass and coated with multiple layers of anti-reflection coatings. This ensures that it provides maximum transmission of light while reducing internal reflections and ghosting. The filter is also parfocal with other filters from the OPTOLONG line, which means you won't have to refocus your telescope when switching between filters.

Overall, the OPTOLONG 2" Filter H-Beta 25nm is an excellent investment for anyone looking to take their astrophotography to the next level. Its superior optical performance and easy-to-use design make it a must-have for any serious astronomer.
