The Celestron Eyepiece and Filter Kit for 1.25" focusers expands your telescope's capabilities with five 4-element Plossl eyepieces ranging from 6mm to 32mm. This 14-piece set includes a 2X Barlow lens to double your magnification options to ten, seven specialized filters to enhance planetary detail, and a foam-lined metal case for secure transport and storage. Each eyepiece features fully multi-coated optics and a 52° apparent field of view, providing a comprehensive upgrade for any 1.25" format telescope.
This kit provides a versatile range of five Plossl eyepieces, each built with a 4-element design and a 52° apparent field of view. The 32mm eyepiece delivers a wide, low-power view ideal for finding objects and observing large star clusters. The 17mm and 13mm oculars offer excellent medium-power views, while the 8mm and 6mm eyepieces provide high magnification for resolving fine details on the Moon and planets under steady seeing conditions.
The included 2X Barlow lens instantly doubles the magnification of any 1.25" eyepiece it's paired with. By using the five eyepieces in this kit with and without the Barlow, you get a total of ten distinct magnifications. This allows you to precisely match the viewing power to your target and the atmospheric seeing conditions on any given night, effectively doubling the utility of your eyepiece collection.
Enhance your views of solar system objects with the included set of six colored planetary filters and a neutral density Moon filter. These 1.25" filters thread directly onto any eyepiece in the kit, selectively passing certain wavelengths of light to boost contrast on specific features. The Moon filter reduces overall brightness, cutting glare to make lunar surface details more comfortable to observe, especially during brighter phases.
The entire 14-piece accessory set comes housed in a durable metal case with die-cut foam interior. Each component has a dedicated slot, ensuring your eyepieces, filters, and Barlow are protected from dust, moisture, and impacts during transport and storage. The case provides a secure and organized way to keep your essential accessories ready for your next observing session.
The 2X Barlow lens is placed into the telescope's focuser first, and then an eyepiece is inserted into the Barlow. This doubles the effective magnification of that eyepiece. For example, the 17mm eyepiece becomes an 8.5mm eyepiece, and the 6mm provides the power of a 3mm eyepiece.
The 13mm, 8mm, and 6mm eyepieces are the best choices for planets. Start with the 13mm to locate and center the planet, then increase magnification with the 8mm or 6mm when atmospheric conditions are stable. Using the #80A Blue or #58 Green filter with these eyepieces can help enhance contrast in Jupiter's cloud bands.
Yes, this is an excellent starter kit. It provides a wide range of magnifications and the essential planetary and Moon filters in one package. This allows a new astronomer to experiment and discover which focal lengths and filters work best for their telescope and typical observing targets without having to purchase each item individually.
Simply screw the desired filter into the threaded barrel of any of the 1.25" Plossl eyepieces. For example, to better see the polar ice caps on Mars, thread the #80A Blue filter onto the 8mm eyepiece before inserting it into the focuser or Barlow lens.
Absolutely. This kit is a perfect match for an 8" SCT. The 32mm eyepiece will provide a wide 63x view for finding objects. The 8mm (254x) and 6mm (339x), especially when combined with the Barlow, will provide high power for resolving details on Jupiter, Saturn, and the Moon on nights with good seeing.
The Moon can be uncomfortably bright, especially through a larger telescope. The Moon filter acts like sunglasses for your telescope, reducing the overall brightness (transmittance) without affecting the color. This cuts down on glare and improves contrast, allowing you to see fine details like crater rims and rilles more clearly.
