Levenhuk Ra UHC 1.25'' FilterFilter for observations of deep-sky objects. Barrel diameter: 1.25''
This filter was designed for observations of dim and low-contrast deep-sky objects. The passband includes the Hß wavelength (4861 Å) and the OIII doublet (4959 Å and 5007 Å). Some planetary and emission nebulae are emitting up to 90% visible light in this range. This filter, therefore, enhances the contrast of nebulae details from 2–5% to 10–50%. T... more

So you wouldn't advise me this filter? So which one should I choose for nebula observing? Levenhuk Customer Service:

This is so bad! I have CELESTRON AstroMaster 114 EQ. so it means that I can't observe nebulae through it? The Orion Nebula for example is so bright - it's impossible that I won't see anything with this filter? is it such a useless thing? Levenhuk Customer Service:
For observing nebulae, please pay your attention to the Levenhuk Ra O-III 1.25'' Filter http://www.levenhuk.com/products/filter-levenhuk-ra-o-iii-1-25/ and the Levenhuk Ra CLS 1.25'' Filter http://www.levenhuk.com/products/filter-levenhuk-ra-cls-1-25/

So can I see nebulae out of it? Levenhuk Customer Service:
Faint deep-sky objects as nebulae and galaxies can be seen through a telescope as grayish cloudlets. However, observing through big powerful telescopes with objective lens diameter of 250-300 mm and more, you can notice faintly discernible colors on the brightest deep-sky objects. But even with the largest professional telescope it's impossible to see visually deep-sky objects so bright and vivid as we used to see on photos.

In general I need a set of eyepieces and filters for my telescope for observing celestial objects such as nebulae, stars, planets, the Moon and the Sun. Nebulae - so they can be seen Andromeda galaxy - it should be visible The Moon - not too much light for comfort observation Eyepieces - so I can see all planets (I saw Neptune - an incredible view!) even if there will be a separate eyepiece for each planet Optical filter - so I can see detailed images of planets So I want my telescope Celestron Astromaster 114 EQ to work to its full potential. Levenhuk Customer Service:
Apparently you meant the model Celestron PowerSeeker 114 EQ; to obtain the maximum practical magnification (i.e. magnification without quality reduction) you will need 4 mm eyepiece (225o), 1,25""; regarding filters, we recommend Solar System Levenhuk F4 Filter Set: http://www.levenhuk.com/products/com-filters_f4_solar_system_set/
