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
