This one really supports the detection of the dark areas on the planet Mars. The details of the clouds of Saturn and Jupiter are also so much more visible through the Filter.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 neutral density filter transmits light uniformly across the entire visual spectrum. It serves as an excellent filter to reduce glare and irradiation when observing the Moon with any telescope 4"(10.2cm) and larger. The ND96 filter may also be employed in the splitting of close double stars where one of the binary pair significantly exceeds the other in brightness. Very flat design, with only 5.0mm light path. FEATURESreduces brightness for a higher contrastideal for observing the mooncan be combined with other colour filtersvery flat design, with only 5.0mm light path SCOPE OF DELIVERY 1x Color Filter #ND96 Moon Filter (0.9 density; 13% transmission)

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. This filter should be used at an aperture of 8“.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.

L-eXtreme Filter for deep sky nebula photography from the city The relentless spread or urbanization and its associated light pollution have become a growing problem for all amateur astro photographers. The current solutions to the problem can be expensive and might include the purchase of a monochrome camera, several types of narrowband filters and a filter wheel. Especially with inexpensive but fast newtonian telescopes, double-lens ED refractors or even achromats, the L-eXtreme filters open up completely new possibilities for high-class astronomical images even from the light polluted city. CMOS cameras can deliver images like monochrome cameras. This new generation of filters makes it possible to take amazing astrophotos directly from the heavily light-polluted city with all its artificial light sources. The dual narrow bandpass for the wavelengths of O-III and H-Alpha and the almost complete attenuation of the interfering light sources of these new filters make this an ideal solution. L-eXtreme Description L-eXtreme is a two 7nm narrow bandpass filter which can be used with one-shot color cameras like DSLRs (digital SLR), color CMOS and monochrome CCD cameras. The convenience and cost-effectiveness of this filter allows amateurs to photograph rich emission nebulas, even in bright, heavily light-polluted skies. The L-eXtreme filter is the better choice for fast optical systems at a competitive price. It isolates the H-Alpha and Oxygen III nebula emission lines so that the contrast and signal-to-noise ratio between nebulae are maximized. The design of our L-eNhance filter is a technical innovation among filters. For people who live in heavily light-polluted areas or when the moon is out, the L-eXtreme is a very good choice. Main Use and Performance This new generation of filters makes it possible to take amazing astrophotos directly from the light-polluted city with all its artificial light sources. The narrow bandpass for the wavelengths of O-III and H-Alpha and the almost complete attenuation of the interfering light sources do not require very large or extremely expensive telescopes. No, especially with inexpensive but fast newtonian telescopes, double-lens ED refractors or even achromats, these filters open up completely new possibilities for high-class astronomical images. Furthermore, with these filters CMOS colour cameras can deliver an image quality that comes close to CCD monochrome cameras. WARNING: These nebula filters are not designed for sun observation. DO NOT LOOK AT THE SUN WITH THIS FILTER. You will go BLIND if you ignore this warning. Coating technology L-eXtreme has a multiple anti-reflective coating on the optical substrate. The L-eXtreme filter uses a precision coating based on ion deposition coating technology. This ensures durability and scratch resistance as well as stability on the CWL (central wavelength), which is not affected by temperature changes. Absolute precision and homogeneity of the coatings as well as maximum values for transmission in the passband and optical density in the off-band range are guaranteed for all filters.  FEATURESProfessional photographic filter for astronomyImproves deep sky emission nebula photography Best choice for extreme light pollution suppression For taking pictures also from highly light-polluted areas Dual-narrow-band filter with high transmission for O-III and H-Alpha linesDoes not require very large or extremely expensive telescopesExcellent results also with fast inexpensive newtonian telescopes, double-lens ED refractors or even achromatsL-eXtreme filter is the better choice for fast systems at a competitive priceCMOS colour cameras can deliver an image quality that comes close to CCD monochrome cameras Filter diameter: 1.25 inches / 31.7 mmConnecting thread: M28x0.6mmSelected optical glass material Spectrum: 300-1000nm Off-Band Blocking: > 99 % Surface Quality: 60/40 (Refer to MIL-O-13830) Fine-optically polished to ensure accurate 1/4 wavefront and highest parallelism over the both surfacesHigh transmission at major nebula emission lines (i.e. H-alpha 656nm and OIII 496nm&500nm)SCOPE OF DELIVERY L-eXtreme filter (1 pc) Dust protection box (1 pc)

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. Minimum 3,5" aperture recommended.What ist a color Filter for and do we really need it ?

The Travel Spotting Scopes are, because of the compact design, perfect for nature observation and bird watching. Especially the accurate and fast focus makes it up and allows for a quick and simple focusing. Armed with fully-coated optics and BK-7 prism, they have a high magnification and still a bright and clear picture. The TwistUp eyecups support the view with as well as without glasses. With the smooth zoom function, a 20-60 times magnification can be realized. The 80mm Version catchs more light for brighter images which makes it possible to look longer during twilight. The lens protection cap, which is attached to the housing, optimally protects the large lens during transport. For better stability you can use the included table tripod. FEATURES spotting scope with big diameter for on the way continuously adjustable zoom range also suitable for eyeglass wearers SCOPE OF DELIVERY Spotting scope Table tripod Bag with carrying strap Protective caps for eyepiece and objectiveManual
