Astrodon UVenus UV Filter

Astrodon UVenus UV Filter£209.00  -  £219.00

Astrodon introduces a breakthrough in UV filters for CCD imaging. A durable, hard-coated UV filter of the highest quality having the best transmission available.

Astrodon OIII 5nm Narrowband Filter

Astrodon OIII 5nm Narrowband Filter£389.00  -  £529.00

Astrodon Narrowband filters set a new bar of performance and durability for imaging and research. We offer 5 nm and ultra-narrow 3 nm bandwidths.

Astrodon Ha 5nm Narrowband Filter

Astrodon Ha 5nm Narrowband Filter£395.00  -  £529.00

Astrodon Narrowband filters set a new bar of performance and durability for imaging and research. The narrow 5 and 3 nm bandwidths enhance contrast of emission targets by lowering your background signal.

Astrodon SII 5nm Narrowband Filter

Astrodon SII 5nm Narrowband Filter£395.00  -  £529.00

If you want the look of Hubble Space Telescope (HST) images, such as the famous “Pillars of Creation” (the Eagle Nebula, Messier 16), then the next filter to consider adding to your collection after H-a and OIII is the SII.

Astrodon LRGB Gen2 E-Series Tru-Balance Filterset

Astrodon LRGB Gen2 E-Series Tru-Balance Filterset£548.00  -  £780.00

Astrodon LRGB Gen2 E-Series Tru-Balance filters have revolutionized CCD imaging. Their popularity is due to their ease-of-use, high optical throughput and great resulting colors for galaxies, star clusters and nebulae.

Astrodon NII 3nm Narrowband Filter

Astrodon NII 3nm Narrowband Filter£579.00  -  £589.00

This is a bit complicated. It is not well known that most H-a filters pass both H-a and NII. H-a emits at 656.3 nm and NII emits most strongly at 658.4 nm (and weakly at 653.8 nm). These are very close together spectrally.

Astrodon Ha 3nm Narrowband Filter

Astrodon Ha 3nm Narrowband Filter£599.00  -  £799.00

H-α (hydrogen-alpha) at 656 nm (nanometers) is deep red in color and the most popular narrowband filter. Hydrogen is ubiquitous in the cosmos and is present in emission nebula.

Astrodon OIII 3nm Narrowband Filter

Astrodon OIII 3nm Narrowband Filter£599.00  -  £799.00

The next filter to complement your LRGBH-a set is an oxygen filter. OIII (“ohthree”) emits light near 500 nm and is a blue-green- or teal-colored filter. Many of my images of planetary nebula and supernova remnants are taken only with H-a and OIII filters.

Astrodon SII 3nm Narrowband Filter

Astrodon SII 3nm Narrowband Filter£599.00  -  £799.00

If you want the look of Hubble Space Telescope (HST) images, such as the famous “Pillars of Creation” (the Eagle Nebula, Messier 16), then the next filter to consider adding to your collection after H-a and OIII is the SII.
