The Celestron 1.25” Eyepiece and Filter Kit is a great way to expand the functionality and enjoyment of your telescope. Inside the metal, foam-lined carry case you’ll find these accessories:

• 32 mm Plossl Eyepiece - 1.25”
• 17 mm Plossl Eyepiece - 1.25”
• 13 mm Plossl Eyepiece - 1.25”
• 8 mm Plossl Eyepiece - 1.25”
• 6 mm Plossl Eyepiece - 1.25”
• 2X Barlow Lens - 1.25”
• #80A Blue Filter - 1.25”
• #58A Green Filter - 1.25”
• #56 Light Green Filter - 1.25”
• #25 Red Filter - 1.25”
• #21 Orange Filter - 1.25”
• #12 Yellow Filter - 1.25”
• Moon Filter - 1.25”

Eyepieces - All five Plossl eyepieces can be used in any telescope with a 1.25” focuser. Each eyepiece features a four-element design with a 52º apparent field of view. The optics are fully multi-coated to improve light transmission and protect the optics. The 32 mm Plossl eyepiece offers a low power, wide field view in most telescopes, the 13 mm & 17 mm focal lengths are good medium-power oculars, and the 8 mm & 6 mm eyepieces provide high magnifications, great for the Moon and planets, especially when seeing conditions are good.

2X Barlow Lens - The included, and very versatile 2X Barlow doubles the magnification of any 1.25” eyepiece. Since this kit includes five (5) eyepieces, you will be able to use them with and without the Barlow, giving you a total of ten magnification options in all. Any other 1.25” eyepieces you already have will also work in this desirable accessory, giving you even more magnification choices. Remember, high magnifications do not always produce clear, sharp results, especially on evenings of poor or moderate seeing conditions. Experiment to find the magnifications that are best for your telescope on a particular night.

Filters - Colored filters can be used to bring out certain details on a planet’s surface or its cloud structure. All of the planetary filters included in the 1.25” Eyepiece & Accessory Kit, as well as the Moon filter, can be used on any 1.25” eyepiece with the proper filter threads, so they are very versatile. Just screw one onto your eyepiece of choice and slide it into the focuser.

The Moon filter is one of the first accessories most new amateur astronomers buy, and for good reason! It helps block out a portion of the light the Moon sends into your eyepiece so that you can see details better. You can also try this filter on Venus; it blocks enough glare so you can observe the planet’s phases more easily.

Metal Case: The sturdy metal carry case has die-cut foam inside to protect and cushion your accessories. Store each one in its appointed place when not in use and you’ll keep them looking and performing like new. The case is even large enough to carry a few extra accessories. Just pull out enough of the foam cubes to make a nest for your eyepiece, camera adapter, etc. A tight fit is better, so remove the least amount of foam possible before testing the fit. You can always remove more if you need to.

Eyepieces - The 15 mm and 6 mm eyepieces can be used in any telescope with a 1.25” focuser. Each eyepiece is fully coated to improve light transmission and protect the optics. The 15 mm Kellner eyepiece offers a nice medium magnification view in most telescopes, and the 6 mm Plossl provides high magnifications, great for the Moon and planets, especially when seeing conditions are good.

2x Barlow Lens - Insert the 2x Barlow Lens between the eyepiece and the telescope and it doubles the magnification of any 1.25” eyepiece. That means the 15 mm Kellner included in this kit will double in power, effectively becoming a 7.5 mm eyepiece, and the 6 mm will provide the magnification of a 3 mm. Any other 1.25” eyepieces you already have will also work in this versatile accessory, giving you even more magnification choices. Remember, high magnifications do not always produce clear, sharp results, especially on evenings of poor or moderate seeing conditions. Experiment to find the magnifications that are best for you and your telescope. T-threads are machined into this Barlow lens, allowing a user to attach a DSLR camera with the addition of an optional T-ring.

Filters - Colored filters can be used to bring out certain details on a planet’s surface or its cloud structure. Both planetary filters, as well as the Moon filter, can be used on any 1.25” eyepiece with the proper filter threads, so they are very versatile. Just screw one onto your eyepiece of choice and slide it into the focuser.

The #80A is a medium-blue filter that enhances the contrast of the cloud belts on Jupiter and the polar ice caps on Saturn. It also can be used to increase contrast on the Moon if you don’t mind the color shift.

The #25 filter is a deep red color and is a good choice when you want to define the polar ice caps on Mars. It’s also fun to use this filter when observing Jupiter. The #25 Red filter blocks quite a bit of light coming through your telescope, however, so it is best used on bright objects with larger aperture telescopes.

The Moon filter is one of the first accessories most new amateur astronomers buy, and for good reason! It helps block out a portion of the light the Moon sends into your eyepiece so that you can see details better. You can also try this filter on Venus; it helps you see the planet’s phases.

Cleaning Cloth & Case: Keep the micro-fiber cleaning cloth stashed in your AstroMaster Accessory Kit case so that it will always be handy. It’s much better to use a micro-fiber cloth on your optics than other wipes or tissue, as it does not leave a residue, and can be reused. Remember to blow or brush any dust particles off of your optics before rubbing them with the cloth.

The black plastic carry case has die-cut foam inside to protect and cushion your accessories. Keep each one in its appointed place when not in use and you’ll keep them looking and performing like new.

What accessories do I need to go with my telescope?

This is a question we get asked every day! We've put together some of our favourite accessories as the BINTEL Observer's Kit #1.

Included are:

BINTEL Plossl 32mm

Most telescopes come with at least one and sometime two eyepieces as standard. They usually offer a medium power around 25mm and a higher power 10mm. These are enough to get you started on your astro journey. While many beginners ask how to increase the magnification of their telescope with additional eyepieces, they often don't realise there's advantages to reducing the magnification with a longer focal length eyepiece.

Lower magnification brings a wider field of view. Some wonderful astro objects in the night sky such as large nebulae and star clusters might not fit into the eyepiece at higher magnifications. They'll need a wider view to see them in their fullest detail.

2x Barlow Lens with T-Adaptor

A Barlow lens effectively changes the focal length of each eyepiece. You insert the Barlow into your telescope and then your eyepiece into the Barlow. This doubles the magnification of each of your eyepieces. Your 10mm eyepiece becomes a 5mm, your 25mm a 12.5mm and so on. It's a quick and effective way of making your telescope more versatile.

This Celestron Barlow also had a T-Adaptor thread. If you have a DSLR camera, simply buy the matching low-cost T-ring for your camera body type (Nikon, Canon etc) here and this can be used to attach a DSLR to your telescope.

Celestron Night Vision Red Torch - RRP $29.95

Why do astronomers use red torches?

No matter the size of the telescope you're using, what's seen through the telescope will be faint. Luckily, our eyes get used to low light after spending a short time in the dark. It takes about 30-40 minutes for us to become "dark adapted". Our eyes are then some 10,000 to 1,000,000 more sensitive to light compared to when we're in full daylight.

(Needless to say, our eyes become less sensitive in the dark as we age and take longer to adapt.... )

This is something we're all used to seeing. At low light, our sight moves from full colour to black and white as different parts of our eyes become active. This dark adaption or night vision is especially important when observing at night. The problem is that even a short burst of white light from a car headlight, an outdoor light or a normal torch can "reset" dark adapted eyes and you need to start the entire process of adapting to the dark all over again.

It's easy to avoid the loss of night vision by using a low intensity red light. This Celestron Night Vision Red Torch lets you adjust your telescope, red maps and book or even attach cameras - all without losing your night vision. Many experienced astronomers will tell you their red lights are some their most used and handiest accessories in their observing toolkit!

Celestron Moon Filter RRP $19.95- yes, I wear my Sunglasses at Night

The Moon is bright enough to cast shadows! It's also sometimes overwhelmingly bright in a telescope eyepiece. The glare can make it uncomfortable to view.

A Moon filter simply reduces intensity to make the Moon easier to observe. With glare reduced, you'll also be able to pick out the finer details on the Lunar surface. This Celestron Moon Filter screws into the base of all 1.25" eyepieces.

Observer's Map of the Moon - RRP $19.95

This is a handy fold out, two-sided map of the Moon.

You can observe features with your telescope and locate them on the map or vice versa. This map also features a directory of all the key lunar regions with coordinates to find them.

On the reverse side of the map, there are close-up photos and information about the most exciting lunar regions to explore. You’ll also find images of the North and South polar regions for reference​. Refer to the lunar observing tips for practical information about using your telescope or binoculars to explore the Moon.

The Observer’s Map of the Moon is waterproof, tear-resistant, and can be folded into an 20cm x 10cm size, making it easy to take along on your next camping trip, star party, or evening in your backyard. When not in use, the Moon map will be a stylish decorative poster on your wall. It makes a great display for your classroom or astronomy club.
