EXPLORE SCIENTIFIC Filter 2" Orange No.21

Filter Set 3 is recommended for Moon & Planets from 150mm (6") Aperture Set 3 includes the following filters: Explore Scientific Filter 1.25" Light Blue No.82A - 0310265 The color of light blue really supports watching the high clouds on Mars. The contrast increases. The dark red structures will be shown even darker, so this is the perfect filter for watching the big red Flecks on the gas planet Jupiter. The rings of Saturn will be accentuated, the structures of the Venus Atmosphere will be even finer. Explore Scientific Filter 1.25" Violet No.47 - 0310272 The purple filter is perfect for watching Venus. Seeing through it, the dark clouds of the Venus atmosphere become even better visible. He also clears up the structures of the rings around Saturn. Using big openings and having a clear sight this filter is also good for watching Merkur. Explore Scientific Filter 1.25" Light Red No.23A - 0310271 The blue/blue green light is totally blocked. The contrast between the card and the lighter zones will enormously increase. This is truly helpful when you watch Jupiter or Saturn. Or for mars, watching the poles. Explore Scientific Filter 1.25" Yellow-Green No.11 - 0310269 Watching the Moon surface through the filter, the contrasts will enormously increase. Same with planet Mars. On the huge planet Jupiter, when using the filter, you can even see the contrasts between the cloud-bands and a lot more details. Starting with a telescope diameter of 8“ and a clear sight, you even get to see various details of Saturn. What ist a color Filter for and do we really need it? Color Filters darken the light slightly, that reaches the eye or the sensor of the camera. This eliminates for instance stronger transitions. The result is that your picture turns out with more contrast which automatically shows more details. FEATURES Made from high-quality optical glass Filter glass is absolutely parallel All optical surfaces have anti reflex coatings Filter housing from black anodized aluminum Filter threads on both ends (female/male) Multiple filters usage is possible SCOPE OF DELIVERY 4pcs color filter 4pcs protection-case

The BRESSER UV + IR Cut Filter makes lunar and planetary images even sharper.Digital astro cameras have a wide sensitivity range that significantly exceeds the spectrum of visible light. Thus, the wavelengths of invisible light in the ultraviolet and infrared are also captured. This leads inevitably to a small additional and of course unwanted blur. The solution is this UV + IR Cut Filter, which allows only light in the visible range 400 nm to 680 nm to pass through and blocks all other wavelengths of light. As soon as these disturbing light waves are cut off, the sharpness of the image and the contrast are increased. Suddenly, details on the surface of Jupiter, for example, can be seen that were previously only barely visible. A clear plus, which can be achieved by this filter.Suitable for BRESSER CMOS cameras and other manufacturers with female camera thread M30 x 0.75 mmAfter removing the original screw adapter with sensor protection glass, the BRESSER UV + IR Cut filter is mounted to the camera instead. This filter has a fine M30 x 0.75 mm external thread for mounting on the camera. The exchange is therefore quick and easy. On the opposite side, i.e. on the telescope side, there is a standard C-mount female thread for mounting other accessories. Note: This filter does not have a standard 1.25 inch (31.7 mm) filter thread.

Filter Set 2 is recommended for Moon & Planets from 100mm (4") Aperture Set 2 includes the following filters: Explore Scientific Filter 1.25" Green No.56 - 0310262 The green filter is to increase the contrasts enormously between the red and the blue regions of the cloud structures on the gas planets Jupiter and Saturn. Seeing our Earth Moon through the green filter, the contrasts of each ray crater become clearly more visible. Explore Scientific Filter 1.25" Orange No.21 - 0310273 This one really supports the detection of the dark areas on the planet Mars.

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 green filter is to increase the contrasts enormously between the red and the blue regions of the cloud structures on the gas planets Jupiter and Saturn.
