SVBONY TWM1 Eyepieces 4mm Telescopes Lens Wide Angle 62 Degree Aspheric Eyepiece HD Fully Coated Telescope Accessory for 1.25 inches Astronomic Telescopes

New to star gazing and didn't know what you need to satisfy your needs;here is something can help you make an educated decision;things to consider:

Make sure that you know your telescope and how to calculate the optimal magnification for the objects you wish to view;the magnification equation:Magnification=objective focal length/eyepiece focal length

Typically;you do not want to exceed 50x per inch of your telescopes diameter or the images will be blurry;for example;you have an 8" lens you get 8x50=400x

So research what the best magnification is for the objects you wish to view

62 degree apparent field of view:
Ultral wide angle for maximum detail and definition across the entire field of view;gets a virtually distortion free image

Fully coated optical lenses:
FMC glass optics increase light transmittance;enhance details on jupiter;saturn;Mars;venus and get high achromatic images

The structure of the optical system:
Aspheric eyepiece designed primarily for planetary observation and perfect for deep sky objects

Standard 1.25" fitting diameter:
Fits for any astronomical telescope with standard 1.25" focuser;perfect for broad field lunar observations

4mm Focal length:
Suitable for lunar observation holes;look more closely detailed at the moon's surface and other planet;perfect for viewing the moon and planets

Applaction:
Watch the scenery;bright celestial observations;nebula;broad field lunar observations;medium sized star clusters;cloudy nebulas and deep sky targets;viewing the moon and planet and so on

Pay attention:Don't look directly into the sun;otherwise it will burn the eyes
