Trigger cable CN3 for Canon

The POLARIE U is an ultra-compact automatic star tracking device that can be easily transported.In addition to the functions of conventional star trackers, which track a camera for a long exposures, accurately tracking the regular movement of celestial objects, the POLARIE U has a speed adjustment function, which allows it to be used as a panning mount too for time lapse photography.Using a smartphone, you can control the shutter release intervals of the images. Through the communication between the smartphone and the POLARIE U Star Tracker, you can control the exposures and take beautiful, sharp pictures of the stars and the Milky Way without getting any star trailing.The Star Tracker is very small and light weight, making it ideal for mobile use or air travel.The Vixen POLARIE U Star Tracker in detail:Star-scape photography (stars and landscape).A silhouetted landscape on earth is photographed together with the starry sky. The beauty of a landscape and the starry sky can be shown together on one photo. POLARIE U opens up a wonderful foreign world of star-scape photography and makes this possible for both beginners and advanced photographers.Conventional telescopic astrophotography photographs a relatively narrow area of the sky. Star-scape photography mainly uses a wide-angle lens and takes impressive photos in which stars, and other celestial targets such as the majestic Milky Way and landscapes are combined. The possibilities of the compositions are endless and a completely new kind of landscape photography opens up.Weight reduction of more than 20% and improved load capacity.The structure of the original POLARIE has been completely changed. The distance between the two bearings that support the rotating shaft is about four times the distance of the previous model. This leads to a higher load capacity despite the weight reduction of 20%. The maximum load capacity is 2.5 kg (approx. 2.5 kg at 10 cm from the centre of rotation) when used for wide-field astrophotography. The maximum load capacity is increased to 6.5 kg (approx. 6.5 kg at 10 cm from the centre of rotation) when a POLARIE Multi mounting block (optional) and a dovetail slide rail DD (optional) are combined. In addition, used in vertical configuration, the POLARIE U can reach a load capacity of 10 kg (approx. 10 kg 10 cm from the centre of rotation) for time-lapse photography and is therefore suitable for heavy camera equipment.Settings via SmartphoneCommunication between tracker and smartphone via the Vixen Polarie U App enables various settings via smartphones or tablet. For star/landscape photography, the speed is selected in user-defined mode, and for time-lapse photography, settings for interval time, exposure, and rotation speed can also be easily programmed.Five different speeds:Star-scape photography (half star speed). This setting is intended for displaying a landscape together with the starry sky. The stars are not tracked exactly, but slower in order not to blur the landscape in the foreground. This way you get beautiful images of the landscape and the starry sky.Wide Field Astrophotography (Star Speed)When this mode is selected, the POLARIE U follows the stars at the same speed as the daily movement of the stars. In this mode, widefield long time exposures of comets, nebulae, star clusters and the Milky Way are made and tracked precisely.Solar Tracking (solar speed)For recording solar eclipses over a long period of time.Moon Tracking (moon speed)For recording lunar eclipses over a long period of time.Custom ModeThis allows you to set the POLARIE U to the desired tracking speed. The initial setting is four times the star speed. If you want to change the setting for a different speed, a smartphone or other wifi device and application software are required.Shoot-Move-Shoot ModeIt is possible to stop the movement of the camera during the exposure and restart it after the end of the exposure. It is also equipped with a camera connector (shutter release) that controls the camera shutter during shooting with SMS or interval shooting. If the camera in use is connected with the cable release, the settings can be easily adjusted using a smartphone. A Wi-Fi connection is required when using this feature. An additional cable is required to connect the camera and POLARIE U together.Autoguider portCommercially available autoguiders can be used with the POLARIE U (Usable only in R.A.).  An important new feature over the original Polarie - attach a small Guidescope, or Off Axis Guider and autoguiding camera to your main camera and use the standard ST-4 protocol port to guide the Polarie U in Right Ascension, ensuring absolute accuracy of tracking (requires additional separate computer, or standalone guider). FEATURES    Speeds: Sidereal rate, 0.5X star speed, sun, moon.

The image plane of many telescopes is not plane, but curved. This results in a picture that has its optimal focus only in the center of the field of view - the edge of the field is out of focus and thus unsharp. The human eye is able to accomodate most of this but a camera will show stars that get increasingly unsharp towards the edge of the field. The Explore Scientific Multi Purpose Curvature Corrector eliminates field curvature in a variety of telescopes - Explore Scientific Apos and many other refractors and cassegrain telescopes. This increases the edge sharpness in the image drastically. Improves edge sharpness not only with Explore Scientific Apos, but also with many other refractor and cassegrain telescopes. This image field leveller fits all Nikon DSLR cameras, but can also be used for other camera types due to the universal T2 thread connection. This requires an optional camera-specific T2 ring. SPECIFICATIONSImage flattener for Nikon DSLR cameras Eliminates the field curvature of ED APO telescopes Can also be used for various cassegrains The image sharpness at the edge is drastically increased 2 inch/50.8mm push-in connector with filter thread T2 threaded connection (M42x0,75mm) Full multi-coating on all lens surfacesStainless steel housing Adapter for Nikon F bayonet included DELIVERY SCOPE Bildfeldebner Nikon (1 piece)

The Vixen focal adapter can be used to connect your DSLR camera to your telescope via a 60-mm thread. The large internal diameter of the adapter prevents shadows at the edges of the image when using a full-frame DSLR camera. The focal adapter can also be rotated to rotate the field of view selection. Three locking screws are provided for clamping.Note: Vixen T2 ring also required for your Canon. In this case, the inner ring is removed from the T2 adapter and clamped using three small grub screws.FEATURES60-mm connection thread for OAZWeight: 56 gT-ring for Canon EOS also requiredPACKAGE CONTENTSVixen focal adapter for Canon EOS
