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 with camera adapter - 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 (see related products below). The lens can also be unscrewed allowing the barlow tube to be used as a universal 1.25" T-adapter for prime focus imaging.
Filters - Coloured filters can be used to bring out certain details on a planets 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 filter 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 dont mind the colour shift.
The #25 filter is a deep red colour and is a good choice when you want to define the polar ice caps on Mars. Its 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 planets phases.
Cleaning Cloth & Case: Keep the micro-fiber cleaning cloth stashed in your AstroMaster Accessory Kit case so that it will always be handy. Its 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 youll keep them looking and performing like new.

Good valve and excellent service It's really refreshing to find a site that combines good value for money with excellent advice and service. Ed at Harrisons provided some great advice in purchasing my first telescope & I wanted a barlow to aid attachment of my DSLR plus moon filter. Good value kit offers both plus more, v.happy (19/02/2018) Glynn - Staffordshire
Excellent service I Brought these eyepieces to replace the existing ones that came with my second hand Skywatcher 130P. they are well packaged in a nice sturdy box and the inclusion of the filters I think make this item ideal for anyone starting out in the Hobby. The service was excellent they arrived next day (02/10/2017) Barry Mears - Hampshire
Right choice for me There are quite a few options on this site for lenses, but after reviewing my current stock of lenses it made sense to go for this package instead. Only used the lenses for one nights viewing so far but I am happy at the moment with them and they are packaged really well. (10/08/2017) Chris Kennedy - Northamptonshire
