Did you know that most telescopes work well for daytime viewing as well as for astronomy? If you have a refractor or a catadioptric telescope (the Schmidt-Cassegrain is the most popular example), and you would like to use it for terrestrial observations, the most useful additional accessory you can buy is an erect-image diagonal.If you look through your telescope with the standard mirror or star diagonal installed, you will notice that objects may be either upside down, flipped so that you see a mirror image or a combination of the two. This is fine for observations of celestial objects, but it can be a little confusing when you are trying to track a boat as it moves through the water, or an eagle as he flies towards his perch.Luckily, this is an easy problem to correct. Simply remove the standard diagonal from the telescope’s focuser or visual back, and install the Celestron 45º Erect Image Diagonal. Now, when you insert an eyepiece, objects will be right side up and left-to-right correct. The 45º angle of this Amici prism diagonal is very comfortable for daytime observations, where the telescope is often in a horizontal position.Please Note: Adding an erect-image diagonal to a Newtonian reflector will not result in images that are right side up and left-to-right correct. The optical design of a Newtonian will always produce images that are rotationally off in orientation. This does not mean that you can’t use a Newtonian reflector during the day, it just means that you have to get used to objects oriented in unrealistic positions.
The Celestron 1.25” Star Diagonal slides into the focuser (1.25”) of your refractor or catadioptric telescope and accepts standard 1.25” eyepieces, allowing you to view objects more comfortably. A diagonal that is angled at 90º helps avoid neck strain when looking through the eyepiece.Please note that a 90º diagonal will display images that are right side up, but left to right orientation will be reversed.
A straightforward 90º Erecting Prism with 1.25" nosepiece. Suitable for use with Refractors, Maksutov and Schmidt-Cassegrain telescopes to produce a correctly orientated view and a more comfortable viewing position.Designed primarily for terrestrial observing, these fully-coated diagonals offer correctly oriented images with high sharpness and contrast.

Explore Scientific 82° Series™ extreme wide field eyepieces are optimized to produce high contrast, high resolution, and superior flat field characteristics.The visual effect of these eyepieces with their long eye-relief and their 82° apparent field is truly a full-immersion experience. Your eye is relaxed, allowing you to easily use the "averted vision" technique to study faint details across a huge field-of-view. The 82° Series eyepieces come with a twist-up rubber eye-guard that raise to the desired height for the comfort of the observer, and as experienced astronomers know, eye comfort is critical when trying to observe at the visual limits of the telescope. To keep internal reflections to a minimum, all internal surfaces of the eyepiece barrel are flat black, as well as the edges of the lenses themselves to minimize the scattering of light within the lenses themselves. All 82° Series eyepieces are fully multi-coated and edge-blackened to produce maximum contrast.

With the introduction of the 68° Series we are pleased to make two important improvements in eyepiece manufacture, the first being 15 layer Enhanced Multi-layer Deposition (EMD™) coatings on all glass-to-air surfaces to gain maximum contrast and waterproofing the eyepiece with the use of Argon gas purging instead of standard Nitrogen gas. Although Nitrogen is a fine choice that will last for many years, Argon is a larger molecule that maintains its protective properties over a wider range of temperatures and is even more resistant to diffusion thereby further extending the protective waterproof environment of the eyepiece body.Through computer-optimized design, a careful selection of optical glasses, and enhanced multi-layer deposition coatings, the Explore Scientific 68° Series™ eyepieces produce long eye-relief and ensure high image-correction, a flat field, and high contrast across the entire image field. An excellent choice for those who make extended visual studies of detail with subtle variations of brightness, and for those who must wear glasses while observing.All 68° Series eyepieces are fully EMD (Enhanced Multi-Layer Deposition) coated and edge-blackened to produce superior contrast.

The "Wow-effect" eyepiece: You see deep sky objects as if you were in space! It makes you forget that you are looking through a telescope. This makes up for an unforgettable observing experience, that even exceeds the expectations of demanding amateur astronomers. Of course, it has the same specifications as the already well established 100° eyepieces: inert gas purged, and waterproof, the high-end EMD coatings are protected from the outdoors. Dust, fungus, humidity and cleaning solutions cannot harm the precious eyepiece for years of observing to come!
These eyepieces with their huge apparent field of view not only gave the observer a panoramic visual experience, but they relax the eye so the observer could pay attention to subtle details for extended periods.These ultra-wide angle eyepieces played a critical role in the military for aiming at targets, and their long eye-relief counterparts helped reduce eye injury from recoil.Each 100° Series Argon-Purged Waterproof eyepiece is internally sealed and purged with inert, dry argon gas to prevent internal fogging, to halt the intrusion of fine particulates and fungus. This also maximizes the life of the internal coatings.To make sure, every 100° eyepiece is tested by submerging them down to 1 meter of water for 30 minutes.All 100° Series eyepieces are fully multi-coated and edge-blackened to produce maximum contrast.

This high quality moon filter is very similar to the Celestron Moon Filter and it has a similar dark green colour. The clear aperture is nearly 22mm. Highly recommended for fast telescopes with f/6 and faster (less then 6) or in refractors as it helps to eliminate the colour aberration of the refractor telescope...
This contrast-enhancing anodized aluminum, optical glass filter is designed to block out the wavelengths of light emitted by mercury-vapor light and other common causes of light pollution, whilst providing higher transmission at critical hydrogen-alpha and hydrogen-beta lines than competing filters. Bright, light-polluted skies appear much darker, and the contrast between object and sky is improved significantly. This contrast-enhancement effect is particularly apparent on nebulae. Unlike stars, emission nebulae give off the light in a very narrow range of wavelengths. This filter allows maximum transmission of the important wavelengths of H-alpha, H-beta and doubly ionized oxygen – the ones most commonly emitted by nebulae. Views of galaxies and star clusters are also enhanced but to a lesser degree. Also improves contrast on reddish planetary detail. Works well in telescopes of all apertures but is highly recommended for use on smaller telescopes up to 114mm diameter, where conventional filters swallow up too much light. Supplied with storage case.

Dramatically Improves Views of Emission and Planetary Nebulas. The UltraBlock is the filter for deep-sky observers located at highly light-polluted sites. Blocks all forms of light pollution - mercury vapor and sodium emission bands - while passing the critical hydrogen-beta and ionized oxygen wavelengths. With an UltraBlock, emission and planetary nebulas "surface" from the washed out background sky. In dark skies, the UltraBlock also enhances the sky presence of a significant number of fainter deep-sky objects over unfiltered and wideband-filtered views. Available in 1.25" and 2".
Advanced multilayer "interference" filter designed to enhance deep-sky observing in moderately light-polluted skies. It blocks the most common wavelengths of light pollution - predominantly produced by mercury vapor lamps - and allows higher transmission of critical hydrogen-alpha and hydrogen-beta lines. Bright, light-polluted skies appear much darker in the field of view and contrast significantly enhanced, particularly emission nebulas like the Orion and Lagoon. Views of galaxies and clusters are also improved. Available in 1.25" and 2".
Omegon pro H-beta 25nm filter - the best way to see the Horsehead nebulaThere are objects that are so interesting that you should get round to observing them at least once. This includes the famous Horsehead Nebula, which adorns so many wonderful astronomy images. But what would it be like to see it 'live' with your own eyes?With the Omegon Pro H-beta filter and a telescope above 8"-10" in aperture, your wish can come true. The filter allows light to pass only in the hydrogen emission region at 486nm. With a bandpass of 25nm, it is particularly suitable for visual observing.The filter will do all of the following:improve contrast between the object and the night sky background;provide a particularly good image under a dark sky;be particularly useful for observing the Horsehead nebula, Cocoon nebula, and California nebula.The H-beta filter offers you something more than just the 'everyday sky'; it lets you explore the extraordinary!Omegon pro filter with its own test certificateYou benefit from the fact that each Omegon pro nebula filter has been fully tested by us and comes with its own test certificate. This certificate is proof of the quality of your filter.
The 1.25" moon filter, consisting of flat steamed glass, is simply screwed into the eyepiece thread. It reduces the brightness of the moon and thus enhances the contrast in the observation. This filter is mainly necessary during the major moon phases since the subjective glare of the moon then is strongest and can quickly become unpleasant.However, the filter doesn't only offer advantages during lunar observation, but it also allows for high contrast observations of planets. It amplifies the surface details that make observation particularly interesting. The filter is most strong in the red/blue range. Thus, objects such as the 'Great Red Spot' and the bands of cloud on Jupiter appear clearer.A particularly disruptive factor during observation is the illumination of street lights. This is blocked in the conventional spectral range so that high-contrast observations are possible. This premium moon filter is much higher quality than similar products: There are some cheap offers in this field where the image quality of the telescope suffers due to the filter. This premium moon filter, however, is characterized by very good characteristics
