TS Optics 1.25" Premium O-III Filter

TS 1.25" Premium O-III filter - noticeable contrast enhancement of mists

The TS O-III filter greatly enhances the contrast of planetary nebulas and gas mists. As a result, the observation of very faint objects even from the city is well possible.

The mode of action of the TS O-III filter:

Countless lights from cities affect the possibilities of astronomical observations. The TS O-III filter almost completely fades out these areas of light, allowing the light components of fogs in the O-III range and H-alpha range to pass almost completely through. This enormously increases the contrast and brings thousands of additional objects within the reach of your telescope.

For which celestial objects is the filter suitable?

The TS O-III filter is particularly suitable for gas mist and planetary nebulae. It lets the light pass in the important O-III range and also in the H-alpha range. Objects such as the North American fog, the supernova remnant cirrus nebula or even planetary nebulae like the dumbbell nebula are significantly enhanced in contrast. Less well-known nebulae are first made visible by the filter.

For which telescopes is the filter suitable?

The TS O-III filter can be used on all telescopes from 90mm opening. The filter is simply screwed into the filter thread of the 1.25 "eyepiece.
