These eyepieces are designed especially for Planetary observations. They are designed to give the highest resolution of subtle contrasts seen on planets and the moon. While many eyepieces are designed to give super and ultra wide angle views, they do so at a loss of details and contrast. These planetary eyepiece are designed to be used for high power, high resolution views where faint details are the objective. There is virtually no halo around bright objects that lose contrast. In addition to lunar and planetary detail, these are ideal for other observations where resolution of fine details is required. They will help resolve close double stars and stars in globular clusters.
The optics are all edge-blackened and have the most modern multi-coatings for maximum contrast.

Most high power eyepieces have a very small eye relief. Your eye has to be pushed into the eye cup to see the image. These Planetary Eyepiece have an excellent eye relief of about 14 mm. This means you can use them with glasses.
The above photographs show the planetary series eyepieces. Click
for second group. Double-Click to return. We are going to
carry the 2.5, 3.2, 4, 5, 6, 7.5, and 9 mm eyepieces in this series.
The 9 mm eyepiece has 6-elements
in 4-groups. The rest of the series have 5-elements in 3-groups.
The eye cup on these eyepieces is adjustable up and down to give you
the most 
comfortable view. Turn it up for use with eye glasses or down without
glasses. Top caps, bottom caps, and a good bolt-type case are included
with all members of this series. This bolt-type case is a roomy, premium one made for us here
in the United States. A lot of dealers are charging up to $4 for these but we include it free.
Please note: These eyepieces are designed to give high power observations, but every telescope has a maximum useful power. Any power may be possible, but if the power used is too high, the image can become too dim. In general, the minimum focal length eyepiece (highest power) can be found as follows:
Fmin focal
length =Focal Ratio / 1.8
In other words, divide your telescope's focal ratio by 1.8 to get roughly the minimum focal length eyepiece recommended for your telescope. This assumes very good to excellent seeing conditions.
