Hello! Is this eyepiece suitable for observing galaxies, nebulae, clusters? It seems like it has a good field of view. Maybe not as good as a wide field eyepiece would have, but still... Can I use this eyepiece with Celestron 2x Barlow Lens With T Adaptor? Levenhuk Customer Service:
Levenhuk Ra LER 5 mm Eyepiece is designed for planetary observations. Apparent field of view: 55°. Yes, Levenhuk Ra LER 5 mm Eyepiece is compatible with the lens.

Hello! The apparent field of view of the Levenhuk Ra Plossl 6 mm 1.25" Eyepiece is the same - 55°. Could you name me some advantages of the Levenhuk Ra LER (compared to Plossl)? As far as I can tell, the front lens is much larger - does this mean it will be easier to catch objects? Levenhuk Customer Service:
Levenhuk Ra LER 5 mm Eyepiece would be the preferable choice due to its design. Levenhuk Ra LER 5 mm Eyepiece has a good eye relief of 20 mm (that means you can observe in glasses). Yes, that's right! If the front lens is large, it will be easier to catch objects.

Do you have eyepieces with focal lengths around 4.4-4.5mm in order to obtain higher increase? Levenhuk Customer Service:
The closest option is Levenhuk Plossl 4 mm Eyepiece - https://www.levenhuk.com/catalogue/accessories/levenhuk-plossl-4mm-eyepiece/

Jeff Foster (2015-10-30 08:12): Positive
Hello I have Celestron Astromaster 114 with 1000mm focal length, is this eyepiece suitable or it's better to try 4mm eyepiece? As far as I remember highest magnification is diameter X 2, so in my case its 228x. If I take 4mm eyepiece, the magnification will be about 250x, which higher than figure obtained from the calculation. At the same time I've seen info online that highest practical power of my scope is 269x. Maybe you happen to know, which is true? I mean 50x is quite a big difference and eyepieces are not all that affordable, so I want to make the right choice. Levenhuk Customer Service:
The highest practical power of your telescope is 228x, so it's better to opt for Levenuk Ra LER 5mm Eyepiece. With this eyepiece resulting magnification will be 200x.

Adam Wallace (2015-09-08 06:31): Positive
