Best For reflector Telescope: Celestron stock Eyepiece

Buy on Amazon

The Celestron Travel 50 and 70 use standard 1.25" eyepieces so they can use any brand of 1.25" eyepiece. It will work with any telescope designed for 1.25" eyepieces, or with a telescope designed for 2" eyepieces with an adapter. The scope comes with a 90 degree star diagonal which puts the bird right way up but of course left is right and right is left with the star diagonal. The extendable eyepiece hood works great in keeping light from reflecting off the eyepiece when using it in a bright field.

There is a tradeoff point between image quality and brightness and in 6" aperture scopes this is not far beyond 150 power. The shorter focal length eyepieces (smaller number of millimeters) will give higher magnification. If the seeing conditions are calm and steady, the eyepiece will provide a high powered view. It offers a no-slip grip, even with gloves on.

• Very clear with good eye relief for comfortable viewing
• Good brand reputation

Most of the eyepieces from this series are very sharp with great field of view and crispy images. A good 18 mm or even a 25 mm eyepiece plus a good Barlow 2X will give you excellent views of planets. The 10 mm eyepiece that comes with the scope is the highest power you can usefully use for bright planet viewing at 90x. It is great for viewing saturn or jupiter and splitting double stars.

The highest power Omni 4 mm eyepiece will provide 112.5X magnification–both will provide a closer view of viewing the moon's craters when good seeing conditions allow. The eyepiece will fit your focuser. The 40mm will give you some wide views, good for clusters like the Pleiades or Orion’s sword. This line of eyepieces is an excellent value.

• Very sharp, excellent color of planets
• 6 mm are bright and clear and maintain good performance across the field
• Good value, very good eye relief

Best For An entry level: Celestron New favorite Eyepiece

Buy on Amazon

Celestron has been making great eyepiece for years, thanks to a combination of clever design and appropriate materials. The eyepieces that come with it are really cheesy and cheaply made. It will drift rapidly across your field of view so each time you adjust the scope you will lose seeing time while vibration settles out. With a 1200 mm focal length, the 7mm would be great for planets and 25 mm good for deep sky objects. It is also compatible with 1.25” star diagonals, focusers and barlows.

With a focal length of just 4mm, this eyepiece offers high magnification to get in close and observe objects when seeing conditions are stable. They are also much lighter and easier to work with.
