Celestron put together this 2" Eyepiece and Filter Kit for Schmidt-Cassegrain and refractor-style telescopes to give users the essentials for planetary observation. All of the accessories are made to fit and accept larger 2" accessories. This kit includes three Plossl eyepieces that provide a wide range of magnifications on any given telescope, five of the most popular colored planetary filters to enhance the views, and a 2x Barlow lens which essential doubles the magnification of any eyepiece used with it. This kit also includes a 90° star diagonal that puts the user's head in a comfortable viewing position when the scope is aimed high in the sky. The diagonal is outfitted with a standard SCT visual-back thread for easy direct-connection, plus an adapter to allow its use on refractor-style focuser drawtubes. An included hard aluminum carrying case protects the accessories while custom die-cut foam on the inside cushions them.

- #80A Blue:
- Most popular for the study of detail on Jupiter and Saturn
- Enhances the contrast on Jupiter's cloud belts
- Enhances details of the Great Red Spot
- Brings out detail in Saturn's belts and polar features
- Also very useful for lunar observing
- #58 Green:
- Rejects red and blue wavelengths
- Increases the contrast on the lighter parts of the surface of Jupiter
- Useful for enhancing the cloud belts and polar regions on Saturn
- Increases the contrast in Mars polar ice caps
- Increases the contrast of atmospheric features on Venus
- #25 Red:
- Blocks the transmission of blue and green wavelengths
- Sharply defines the contrast between the cloud formations and the lighter-toned surface features on Jupiter
- Useful for definition of the Martian polar ice caps and maria
- #21 Orange:
- Reduces transmission of blue and green wavelengths
- Increases the contrast between these blue/green areas and red/yellow/orange areas
- Sharpens the boundaries between these areas on the Martian surface
- Sharpen the contrast in Jupiter's belts and to bring out the Great Red Spot
- Slightly increases surface details on Saturn
- #12 Deep Yellow:
- Enhances red and orange features on Jupiter and Saturn, while blocking blue and green wavelengths
- Lightens the red and orange features on Mars, while reducing, or blocking, the transmission of blue and green areas - increasing the contrast between the two
- Enhances the blue clouds in the Martian atmosphere
