Filters for Viewing

The NPB is the ONE filter to have if you have just one, and now regarded as the top narrowband  (UHC type) filter in the world. Judged by renown astro-equipment author Phil Harrington as the best of nine leading competitors in the Astronomy Magazine review "Secret Weapons" (August 2005). With the NPB more objects show enhancement, than any other filter in it`s class.

The VHT is "mid-band" Nebula/LPR filter that is the perfect match for smaller scopes, or binoculars that can use filters. This filter provides a good balance between the NPB and GCE with regards to contrast vs. field background and star brightness.

The GCE takes a different approach to Wideband LPR filters by employing a "Notch" design which excludes all the bad stuff, from 540 - 590 nm, while allowing the rest of the visible spectrum to transmit over 90%.

The DGM Optics HPOIII is your perfect compliment to the NPB when you need a more aggressive Nebula filter that really shines with larger scopes. This filter has a bandwidth of approx.

A moon filter reduces irradiation, glare, and excess image brightness in lunar observing. It also improves the contrast between lunar albedo features.

The Lumicon 1.25" Comet Filter, a narrow band-pass filter (25nm), isolates the 501nm OIII line and both C2 lines at 511nm and 514nm.

The 1.25in Deep Sky is Lumicon's most popular nebula filter. It blocks all high & low pressure mercury and sodium vapor lamp light, neon lights and airglow, while transmitting the rest of the visible spectrum.

The Lumicon 1.25" Lunar & Planetary Filter Set, LF5045, is an excellent "starter-kit,"

The legendary Lumicon 1.25in OIII narrow band-pass filter isolates just the two doubly ionized oxygen lines (496 and 501nm lines) emitted by diffuse, planetary and extremely faint nebulae.

The Lumicon 2" Comet Filter, a narrow band-pass filter (25nm), isolates the 501nm OIII line and both C2 lines at 511nm and 514nm.
