Product information "Vixen VA225C Autoguider Camera"
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.

Vixen finder scope 7x50 with crosshairs and illumination
£149.00*
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

EXPLORE SCIENTIFIC Deep Sky Astro Camera 16MP
£1,099.00*
High resolution deep sky camera with large Panasonic CMOS sensor and active cooling. Enter the world of astrophotography now. With the new EXPLORE SCIENTIFIC DEEP SKY ASTRO camera you get a modern complete package for the comfortable shooting of astro photos and videos. Finally, an easy-to-use camera for capturing galaxies, star clusters, the moon and even planets with high resolution and low sensor noise. Thanks to the fast USB 3.0 computer interface, all image data is transferred within a few seconds. Long waiting times are now history. Simply connect the camera to your telescope using the T2 female thread (M42.0.75mm) or the supplied 2" (50.8mm) plug-in adapter and after installing the drivers and the included EXPLORE Capture recording and editing software, you are ready to take the first real astro photos with a highly specialized camera for your application. The EXPLORE Capture Pro software included in delivery not only offers the basic functions required for image and video capture, but also many helpful special functions for image post-processing and camera setup. Functions such as live image display, exposure settings, white balance, dark image print, stacking, timelapse recording and much more can be configured individually. Especially the very sophisticated software makes your entry into astrophotography really easy. With the automatic settings you can produce absolutely presentable results without any previous knowledge. If you like, simply switch off the automatic settings and gradually dare to adjust the individual professional settings. The new EXPLORE SCIENTIFIC DEEP SKY camera has a highly sensitive and very low-noise Panasonic CMOS sensor which is additionally cooled down to 40°C below ambient temperature by the two-stage thermoelectric cooling. In contrast to normal DSLR cameras, this guarantees much lower noise and fewer hot pixels in your shots. The images are not only much sharper and more brilliant, but also contain more usable image information. Through the controlled setting of the desired camera temperature, the creation of dark frames under reproducible shooting conditions is possible at any time. The large-format CMOS sensor with 21.9mm diagonal also allows large image fields and simplifies the adjustment and centering of objects considerably. The camera has a built-in USB hub with 2 x USB2.0 ports at the rear. Connect your additional autoguider camera or motor focus etc. via a short USB cable and reduce the risk of cable spaghetti and cable breaks. Separate cable connections between your accessories and your computer are no longer necessary. A sturdy hard case for the camera plus accessories is also included. IMPORTANT NOTES: Don't get confused by the megapixel data and the contrary price structure. In the field of astronomy, the key criterion is not the sensor resolution but the maximum light sensitivity. The main goal is to capture as much light as possible in a short time.DOWNLOAD latest camera software and drivers see download folder "Manuals" or here: https://www.touptek-astro.com/downloadsSample photos made by Lóránd Fényes in Hungary: https://fenyeslorand.hu/asztrofotok/Field of view for different focal lengths in arc minutes and degrees: 400 mm - 151´x 114´ (2.5 x 1.9 degrees) 500 mm - 121´x 91´ (2.0 x 1.5 degrees) 600 mm - 101´x 76´ (1.7 x 1.3 degrees) 700 mm - 86´x 65´ (1.4 x 1.1 degrees) 800 mm - 76´x 57´ (1.3 x 0.9 degrees) 900 mm - 67´x 51´ (1.1 x 1.9 degrees) 1000 mm - 61´x 46´ (1.0 x 0.8 degrees) 1250 mm - 48´x 37´ (0.8 x 0.6 degrees) 1500 mm - 40´x 30´ (0.7 x 0.5 degrees) 1750 mm - 35´x 26´ (0.6 x 0.4 degrees) 2000 mm - 30´x 23´ (0.5 x 0.4 degrees) FEATUREScamera type: ASTRO Camera 16.0MP ATR3CMOS16000KPA data output: single pictures and video image Sensor: Panasonic NM34230PLI CMOS Color Sensor adjustable resolution: 4648x3506 / 2304x1750 / 1536x1168 adjustable binning: 1x1 / 2x2 / 3x3 frame rate per second (FBS): 22.5 / 43 / 48 physical sensor size in pixels: 4648 x 3506 megapixel: 16 MP sensor size: 17.6 x 13.3 mm (4/3 inch) pixel size: 3.8 µm x 3.8 µm bit depth: 12 Bit backfocus: 17,5 mm shutter Type: rolling shutterinternal camera memory: DDR 3 RAMthermoelectric cooling with fan: yes, up to 40°C below ambient temperature adjustable exposure times: 150µs to 60min operating temperature: -10 to +50°C (30-80% RLH) cable length USB 3.0: 150cm DC cable length power supply: 200cm CNC machined aluminium housing camera diameter: 80mm; length: 102mm camera weight: 0,53 kg camera connection diameter: 2.0 inch ( 50.8mm) camera connection thread: T2 (M42x0,75mm) filter thread: Yes, 2.0 inch in receptacle camera connection to PC: USB 3.0 built-in USB hub with 2 x USB 2.0 ports power supply: Power supply 12 Volt 3,0 Ampere included software: EXPLORE Capture included camera driver and ASCOM driver includedoperating system: WINDOWS 10 + 11 PC requirements: CPU Intel Core2 2.8Ghz or higher / 2 GB Ram / USB 3.0 SCOPE OF DELIVERYDEEP SKY ASTRO Camera 16.0MP telescope adapter T2 thread to 2.0" (50,8mm) USB 3.0 connection cable 150cm power supply 230V/12V3,0A dust cap software CD hard case instruction manual
