We always suggest astronomers buy quality narrowband filters from renowned optic brands. But still, there are a few facts that one should consider before buying a narrowband filter. And they are- 


Optical quality

The most important part of a narrowband filter is the lens of the optic. So it is essential to choose a filter with high-quality optics. Always try to buy one that features fully polished optics because this type of lens offers you high transmission, which is very important for astrophotography. 


Mount system

Choose a narrowband filter that can be mounted easily with your telescope and camera’s lens. Do not choose a narrowband filter that is too hard to mount. If you use a mount like this there is a possibility you will get a scratch on the lens of the filter. There is no doubt that the lens is the most important part of a narrowband filter. And you don't want any scratch or spot on the filter.


Light pollution blocking performance

A narrowband filter works to prevent stray light from your astrophotography. If a filter can not block the stray light properly, then you will not get quality pictures. So buy a narrowband filter that offers you light pollution blocking performance of extreme level. 


Purpose

Although this point is not related to the quality of a narrowband filter, it is as important as the other points. Before buying a narrowband filter, you need to know for which purpose you are buying that. There are different types of narrowband filters for different purposes.



Frequently Asked Questions About Narrowband Filters



What is a narrowband filter?

A narrowband filter is a type of astronomical filter that is considered to be a telescope accessory. This thing helps to capture a tiny part of the visual spectrum. Just like its name, narrowband have narrow filters. It is designed to pass very restricted band wavelengths around specific emission lines of Ha, SII, OIII. Here Ha stands for Hydrogen-Alpha, SII stands for Sulfur II, and OIII stands for Oxygen III.


What are the benefits of narrowband imaging?

Narrowband filters are great for taking astrophotographs. You can tune to specific emission lines with a narrowband filter. It increases contrast by eliminating the continuum. You will see different structures (for example- OIII, SII, NII, etc.) by using it. Not only that, these filters extend imaging time with moonlight and allows you to take images in a light polluter area.  


What filters do I need for astrophotography?

For astrophotography, the most common filters are mentioned below

  • Hydrogen-Alpha (656nm)
  • Hydrogen Beta (486nm)
  • Oxygen (OIII – 496nm and 501nm)
  • Sulfur (SII – 672nm).


Conclusion



Observing the night sky filled with stars and the moon has always been a very satisfying way of relaxation. And when it comes to observing the planets, nebulae through a telescope are much more exciting and educative at the same time. Only a tremendous narrowband filter can give you the utmost pleasure to watch the Celestron.

And that is the reason why we have chosen the best narrowband filters for you. Let us know your opinion about us. Leave your words in the comment section. We will be back to you as soon as possible.
