Singularity by Vaonis is the control center for your Stellina and Vespera observation stations. This intuitive mobile application allows you to explore the Cosmos with ease. Receive personalized recommendations on which objects to observe according to your geolocation and the astronomical calendar. Learn more about the history of the Universe and immortalize your trip by photographing galaxies, nebulae and star clusters. AUTOMATIC SETUP Just press the button, and let Stellina and Vespera do the rest. Your new companion will use your GPS to find its position on Earth, adjust its focus and be ready to take you anywhere you want in less than 5 minutes. AUTOMATIC ALIGNEMENT AND TRACKING Choose your destination in the Singularity object catalog or enter the celestial coordinates of the object. Your station will automatically point to the selected area, and track it to maintain optimal viewing conditions. IMAGE PROCESSING It only takes a few seconds for Stellina and Vespera to deliver the first image of your destination before compiling dozens, hundreds or even thousands of other images in real time, progressively revealing ever greater details and colors. SPACE CENTER Take control of your station from the Space Center: prepare your observation evening by checking the weather forecast, create and manage your observation locations, check the parameters of Stellina/Vespera... You can also read the astronomical news or our advice on Stellina and Vespera on our blog while waiting for nightfall. MOSAIC MODE CovalENS is the first automated “panorama mode” ever embedded into a telescope. This unique patented technology, developed by Vaonis, allows you to take several photos of a same stellar region and then automatically stitch them together, thus offering users a larger view (field) of the universe. SOLAR MODE Observe easily and safely the closest star to Earth during the day with the Vaonis solar filters. The Solar Mode allows you to observe and capture sunspots that show the intensity of the Sun’s activity. EXPERT MODE Access an unlimited number of objects with coordinate pointing. Customize your camera's exposure time and gain to generate initial files for manual processing using image editing software. PLAN MY NIGHT Program your observation station for the night and let it explore the Universe on its own. After a good night's sleep, recover your photos on a USB key (Stellina) or via Wi-FI FTP protocol (Vespera). SHARE YOUR JOURNEY ON SOCIAL NETWORKS Your trip is over, share it! Show the world your photos on social networks and join our community of explorers, using the hashtags #myStellina or #myVespera.

STAR BOOK Wireless is an app for a smartphone that allows for radio controls of the equatorial mount with a Wireless Unit attached. The wireless LAN connection between the smartphone and the Wireless Unit makes you operate the equatorial mount with no cables and enables you to use celestial navigation functions, including automatic GO-TO navigation. Applicable equatorial mounts:SX2、SXD2、SXD2-PFL、SXP、SXP-PFL、SXP2、AXJ (Encoder cannot be used together)、AXD2、AXD、AP Functions Available with the App Moving the Telescope in X-Y Directions Swiping on the screen of star charts with your fingers will move the telescope in the corresponding direction. Also, fine movements are available by enlarging the screen. Zooming in or out of the screen is ready with the zoom slider. Celestial Navigations You can select celestial objects you desire to see from the lists of different celestial objects (Stars / Planets / Messier objects, NGC objects, IC objects / Comets, and so on) and introduce them into your telescope automatically. (SCOPE MODE) In this mode, swiping motions on the star chart are linked to a movement of the telescope. The telescope can be slewed in any direction freely. (CHART MODE) In this mode, you can select the celestial objects you want to introduce into your telescope from the star charts on the screen. You can choose a named celestial object seen inner the center green circle or bring a field of view of the telescope to the center of the star chart. Alignment* After introducing the target celestial object in the center, you can match the direction of the telescope's field of view to that celestial object by tapping "ALIGN" for alignment. You can view and delete alignment logs by pressing "ALIGN" a little longer. *The alignment is the work of matching the position information from the celestial coordinates stored in the app with the location of stars visible in the sky. Firmware Update You can update the firmware on your Wireless Unit with the application. Nighttime Visibility You can secure the visibility on the screen during nighttime use by changing the screen illumination to red
