Leviathan Filter Gallery

Here are images made using the Leviathan Spectral Pro:

Horsehead Nebula with Alnitak by John Walsh. A relatively short 1.5 hours on this target with a nearby full moon is perhaps the best endorsement yet of the Spectral Pro's halo performance. Imaging the horsehead nebula almost always results in halo's on Alnitak but here the Spectral Pro handled Alnitak extremely well.

The Elephants Trunk by Gary Palmer - Gary uses his custom colour palette from Spectral Pro data to show the OIII clearly when in standard processing techniques, usually the Ha will dominate. Gary remarks that the Spectral Pro provides a high amount of OIII making such a processing technique possible.

The Elephants Trunk by Ben Saunders - In this version of the Elephants trunk, a standard colour palette reveals the reflection nebula at the tip of the trunk. This is rarely imaged with OSC filters but is very clear with the Spectral Pro. The image also shows the OIII and Ha blending together with a nice colour contrast.

VdB132 in HOO palette by John Walsh - the Spectral Pro is designed to bring out the reflection nebula within a dense Ha field in the same exposure.

LBN331 by John Walsh
The Spectral Pro is excellent for imaging Emission nebulae as well as reflection nebulae and broadband targets.

VdB132/NGC6914 by Ben Saunders - In this example the reflection nebula is beautifully revealed in the same exposure as a dominant Ha field. This shows the versatility of the Spectral Pro.
