Vixen mounting base for finder scope

Thanks to the large aperture of 50 mm, the Vixen 7x50 finder scope immediately reveals many objects that are not visible in smaller viewfinders. This makes it easy to adjust the telescope to the target object. The red illumination of the finder scope can be dimmed to different levels.The eyepiece is detachable (31.7 mm diameter) so that a CMOS camera with 31.7 mm diameter (available separately) can be attached and used as an autoguider. The eyepiece unit with crosshairs is also removable in order to use 31.7 mm diameter eyepieces (sold separately) with different focal lengths. This allows the finder scope to be operated with various magnifications.The lens is designed to be compatible with CMOS cameras. The distance between the bottom of the 31.7 mm sleeve on the camera side and the sensor surface should be approximately 17 mm. However, the focus position may vary depending on the camera, so you should adjust the guiding camera for focus before use. The focus of the optics is adjusted by rotating the lens. First, the black lock ring on the main optics must be loosened. Then, the focus can be adjusted by turning the lens mount. Please also read the operating instructions for the viewfinder and the CMOS camera used.If the focus of the viewfinder has been adjusted, the focus position must be readjusted when using the eyepiece unit.FEATURESMagnification: 7xAperture: 50 mmLenses: coatedCrosshairs: illuminated in red, dimmableDimensions: 220 mm × Ø 58 mmWeight: 467 gSCOPE OF DELIVERY7x50 viewfinderEyepiece unit with illuminationCR2032 batteryInstruction manual

The Vixen VA225C autoguider camera is designed to tackle common challenges in astrophotography, such as atmospheric interference and minor tracking errors that can cause star trails during long exposures. When paired with an optional guide scope, this highly sensitive colour CMOS camera continuously monitors star positions and automatically adjusts your equatorial mount in real time to correct for any deviations. This allows you to capture sharp, long-exposure images — especially useful when using telescopes with longer focal lengths. Beginner-friendly operation The VA225C makes it easy for newcomers to get started with autoguiding. Simply connect the camera to your telescope mount using the included ST4 cable for fully automated tracking control. The dedicated “Vixen Autoguider” PC software offers three preset guiding modes — City, Suburban, and Dark Sky — tailored to different viewing conditions. You can also fine-tune the settings to suit specific locations and atmospheric conditions if needed. Accurate polar alignment — without a polar finder With its built-in plate solving functionality, the VA225C allows for precise polar alignment without the need for a separate polar finder. You can check the alignment accuracy in real time via the software interface and make direct adjustments on the spot. This feature simplifies your setup process and ensures optimal conditions for successful astrophotography sessions. Exceptional sensitivity and flexible connectivity Thanks to its excellent light sensitivity, the VA225C can reliably detect suitable guide stars even with very short exposures. The camera comes with a 1.25" nosepiece for connection to guide scopes or off-axis guiders, a 1.25" filter thread (M28.5x0.6), and a C-mount thread (1" x 1/32"). We recommend the Vixen 7x50mm Finder Scope II (sold separately, item no.: X086161) as a guide scope. Its parfocal design ensures the focus remains consistent when switching between an eyepiece and the camera — so your guide star stays locked in view.

One of the most important obstacles for the exploration of the night sky is the brightening of the night sky by artificial lights, such as streetlights. The night sky is not really dark in the vicinity of towns or cities, which reduces the visibility of objects beyond the solar systems enormously. Depending on the type of the celestial object it is possible to increase the contrast dramatically by blocking the annoying artificial light. The EXPLORE SCIENTIFIC O-III filter uses a characteristic property of the so called emission nebulae. Those objects glow in special colours, the so called emission lines. Those emission lines are linked to chemical elements - in this case oxygen. The EXPLORE SCIENTIFIC O-III nebula filter blocks all other colours (and thereby nearly all of the artificial light) and only the two emission lines of the oxygen can pass the filter. The result is astonishing: suddenly nebulae are visible at locations that were completely empty without filters. In suburban skies for example the veil nebula NGC 6992 is almost not visible with a 200mm telescope. By using this filter you can see the nebula and its structures without problems. A must for every visual observer. The EXPLORE SCIENTIFIC nebula filters come with a individual test certificate - your guarantee to receive a premium filter.FEATURESenables the observation of so called emission nebulaeblocks almost the entire artificial lightonly the two emission lines of ionised oxygen passes the filterWHAT'S INCLUDED1x 2" O-III nebula filter
