Astro Essentials 1.25" #47 Violet Filter

Astro Essential colour filters for astronomy are most often used to enhance contrast when observing the Moon and planets.

Results depend on seeing conditions, the telescope and the target being observed or photographed but the right filter can make a significant difference when, for example, viewing the lunar surface or teasing detail from Jupiter's weather bands or Saturn's rings. 

See our handy guide to colour filters and how they can help improve your lunar and planetary visual observing.

Wratten #47 Violet Filter

  • The most popular use of this filter is to help reveal details in the cloud tops of Venus. It can also help to enhance lunar definition.
  • Use to observe Mars, it helps to reveal high clouds as well as haze in the polar regions. Used on Saturn it can help to reveal details within the ring structure.
  • The low light transmission of this filter means that it should only be used on larger telescopes.

Full Moon Filter

Several reviews on this filter.... for and against. Used it last night on the full moon and it certainly cuts out the glare allowing only 3% of light through. Enhances contrast on crater rays and objects on the moons periphery. Main benefit is not being 'blinded' in one eye when switching to other night sky targets. Tried variable polarising filters but prefer this as long as you don't mind a violet moon. As usual, excellent and prompt service from the FLO team. I hope the "comes with snow" sticker on the packaging wasn't a weather forecast!😉

For my purposes the title should perhaps read Micro Essentials 1.25" #47 Violet Filter, as I use the item during my microscopical investigations.. I use this hgh quality optical device to add effects to the photomicrographs which I produce, and find it to be ideally suited to this purpose and also to be perfectly compatible with the other equipment that I use.
