Product Description

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 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 lightweight, 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 center of rotation) when used for wide-field astrophotography. The maximum load capacity is increased to 6.5 kg (approx. 2.5 kg at 10 cm from the center 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 center of rotation) for time-lapse photography and is therefore suitable for heavy camera equipment. Settings via Smartphone Communication 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 Mode This 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 Mode It 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 port

Commercially 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).

POLARIE is a new and unique camera accessory for photographing the night sky, with perfectly point-like stars being tracked. Using the simplest solution, it makes the experience of photographing the night sky more accessible for everyone. The multi-functional mode dial is adjustable for sky- and landscape-, moon-, sun- and star-tracking. Polar altimeter for a fast focus. Also included: USB connection for external power supply and a built-in compass for quick orientation. Available as optional extra accessories are a polar finder telescope for exact alignment with the celestial pole for long-exposure photography including into the telephoto range, and a tripod.

最高速度が10倍というのは私にとっては遅すぎ。30倍は欲しかった。 追尾精度は悪くない。 稼働時間が短くなってもいいので単3ー2本駆動で少しでも軽くしてほしかった。どのみち長時間使用するときは外部給電するので。 寡占状態なので仕方ないと思うが、他のV社の製品と同様、ぼったくり価格だと思う。本体の価格も高いがオプション部品が異様に高い。

旧ポラリエWTから買い足し、2台で運用する予定。旧ポラリエの備品がそのまま使えて有利だ。極軸微動雲台DXと相性がよく、プレートホルダーの型が一致していて爪で引っかかるようになっている。・極軸微動雲台DXhttps://amzn.asia/d/gHIz7mq『極軸望遠鏡PF-LⅡ』と『極望アームPU』のセット品を購入するか、・セット品https://amzn.asia/d/55svRh2ポラリエWTで使っていた極軸望遠鏡PF-LⅡをこのポラリエU用として流用できるが、その際、ポラリエWT専用アダプターを取り外す加工が必要で、加工方法を下記PF-LⅡの私のレビューに記載(厳密にはVixenさんにお問い合わせしてください)。https://www.amazon.co.jp/gp/customer-reviews/RJ1RYVRW4A53T?ref=pf_ov_at_pdctrvw_srp・極軸望遠鏡PF-LⅡhttps://amzn.asia/d/ggsLWAB・極望アームPUhttps://amzn.asia/d/4AHpvNn他、Vixenのパノラマクランプや雲台プレート、マルチ雲台ベース等、ポラリエ共用で使える。・クイックリリースパノラマクランプhttps://amzn.asia/d/enMlTzB・スライド雲台プレートhttps://amzn.asia/d/fASEPQT ・ポラリエ用マルチ雲台ベースhttps://amzn.asia/d/2qniatZ・ポーラーメーターhttps://amzn.asia/d/cwfnKeb・バランスウエイトWT1kghttps://amzn.asia/d/h2l2Kps初試用では月や太陽(減光NDフィルター:ND10000程度以上必携)が簡単に追尾できた。今後、惑星や天の川の追尾撮影が今まで以上に上手くできそうだ。筐体はホワイトな照りがあって高級感が高い。外部オートガイダー対応で電力がUSB-C端子入力になって、拡張性アップした点が買いだ。要望として、備品も一緒に入れて移動できる専用ケースがあれば、更に便利で高級感アップだ。

3/8→1/4インチ変換アダプターネジが1個付属していたが、日本仕様なら、2個無いと使用出来ないのでは?本当は星5つにしたいけど180円程度の上記アダプター一つが足りないだけで接続出来ず、結果1ヶ月程もの時間ロスになりました。

前々から気になっていたポラリエUですが、Amazonのポイントアップキャンペーンに合わせて、一般的な販売価格より一万円以上安く手に入れることが出来ました。無事に配送され開封後、回転軸のあそびを確認したところピクリともせず、赤道儀並の剛性感に驚いた次第です。実際の使用でも極軸を簡易的に合わせただけにも関わらず、XT-4にTAMRON18~300の暗いズームレンズを付けて試写したところ、50mm付近で2分、200mm付近で1分露光してもほぼわからない程星が点像に撮れたのには驚きました。架台には手元にあるスカイメモの架台を使いましたが良い組合せだと思います。話しは逸れますが、このTAMRONズーム、露出さえ掛けられれば色収差が目立たず星撮影にも意外と使えると感じ新たな発見をしました。ポラリエUは、広角から中望遠のカメラレンズを使って気軽に星撮影する方の最強の味方だと思いますよ。
