The optics, two sensors, motorized mount, filters, and battery all fit into a 1.65 kg unit, not including the tripod. You place it on the included tripod, turn it on, and then control the session using the Seestar app on a smartphone or tablet. Observation takes place on the screen, not through the eyepiece.<\/p>\n<p>The telephoto camera, featuring a 30-mm, f\/5.3, four-element apochromatic lens, is used for nebulae, clusters, galaxies, the Moon, and the Sun. The wide-angle camera, with a 43.5\u00b0 field of view, is used for the Milky Way, star trails, and nightscapes. In both cases, images are captured at 1440 \u00d7 2560 pixels (2K) in portrait orientation.<\/p>\n<h3>Key points<\/h3>\n<ul>\n<li>Smart dual-camera telescope, controlled via the Seestar app.<\/li>\n<li>Telephoto camera: 30 mm aperture, 160 mm focal length, f\/5.3, four-element apochromatic lens, 1\/1.8-inch SC485SL sensor, 3\u00b0 field of view.<\/li>\n<li>Wide-angle camera: 6 mm focal length, 3.4 mm aperture, f\/1.75, 1\/2-inch IMX586 sensor, 43.5\u00b0 field of view after sensor cropping.<\/li>\n<li>1440 \u00d7 2560-pixel (2K) resolution on both cameras, in portrait orientation.<\/li>\n<li>Built-in UV\/IR-Cut, Duo-Band (OIII 30 nm \/ H\u03b1 20 nm), and Dark filters, plus a magnetic solar filter included.<\/li>\n<li>Azimuth mount with GOTO, tracking, live stacking, and an equatorial mode available.<\/li>\n<li>A database of more than 80,000 objects, four shooting modes, scheduling, and remote control.<\/li>\n<li>6,000 mAh battery (up to 6 hours according to the manufacturer's lab tests), 64 GB of storage (approximately 45 GB usable), Wi-Fi, Bluetooth, NFC, and USB-C.<\/li>\n<li>Dimensions: 210 \u00d7 140 \u00d7 80 mm; weight: 1.65 kg without the tripod; base thread: 3\/8\u2033-16.<\/li>\n<\/ul>\n<h3>Telephoto camera: 30 mm, f\/5.3, 3\u00b0 field of view<\/h3>\n<p>The telephoto lens features a four-element apochromatic optical system, a 30-mm aperture, and a focal length of 160 mm, resulting in an aperture ratio of f\/5.3. The lens is folded inside the body, which allows for this focal length. The sensor is a 1\/1.8-inch SC485SL CMOS sensor with a resolution of 1440 \u00d7 2560 pixels in portrait orientation, for a total of approximately 3.68 million pixels. The field of view is 3\u00b0, corresponding to a full-frame equivalent focal length of 815 mm. The focus range extends from 6 m to infinity.<\/p>\n<p>It is used for nebulae, star clusters, and galaxies, as well as for the Moon and the Sun, with the included solar filter. The app can automatically stitch together overlapping images taken with the telephoto lens to widen the field of view. However, according to the manufacturer, the S30 Plus does not support stitching wide-angle mosaics, panoramas, or Milky Way arcs.<\/p>\n<h3>Wide-angle camera: 43.5\u00b0 for the Milky Way and landscapes<\/h3>\n<p>The second camera has a focal length of 6 mm, an aperture of 3.4 mm, and an f\/1.75 aperture ratio. It uses a 1\/2-inch IMX586 CMOS sensor. The image is cropped to 1440 \u00d7 2560 pixels in portrait orientation, providing a 43.5\u00b0 field of view, which is equivalent to a 55 mm full-frame focal length. The focus range extends from 0.1 m to infinity, which also allows for close-up shots in landscape mode.<\/p>\n<p>This camera is designed for the Milky Way, star trails, and time-lapse videos. The two cameras cannot be used at the same time: you must choose one or the other. The Milky Way can be photographed in a sufficiently dark sky. In areas with heavy light pollution, the signal may be limited, as the manufacturer notes.<\/p>\n<h3>Built-in filters and sun filter<\/h3>\n<p>Three filters are built-in and can be activated from the app. A UV\/IR-Cut filter is available on both cameras. The telephoto lens also features a Duo-Band filter, with 30 nm passbands for OIII and 20 nm for H\u03b1, as well as a Dark filter for calibration shots. The Duo-Band filter isolates the emission lines of nebulae and attenuates some of the artificial light, which helps when photographing emission nebulae from an urban environment or a balcony.<\/p>\n<p>For white-light solar imaging, a magnetic-mount solar filter is included. It must be installed according to the manufacturer\u2019s instructions before pointing the camera at the Sun. Pointing the camera at the Sun without this filter may cause permanent damage to the device.<\/p>\n<h3>Automatic Time Tracking, Monitoring, and Enforcement<\/h3>\n<p>The azimuth mount aligns itself when powered on, then automatically returns to its initial position. You select a target from the app\u2014choosing from more than 80,000 objects\u2014and the telescope points at it, tracks it, and stacks the exposures. Tracking speeds range from 1\u00d7 to 1,440\u00d7. An active anti-fog heater limits condensation on the optics when the temperature drops.<\/p>\n<p>There are four modes available: \u00abStargazing\u00bb for deep-sky objects, \u00abMilky Way\u00bb for the Milky Way and star trails, \u00abSolar System\u00bb for the Sun, Moon, and planets, and \u00abScenery\u00bb for landscapes and terrestrial subjects. A scheduling mode sequences multiple targets throughout the night. The app also allows you to control a device installed at a remote location. According to the manufacturer, this remote control feature is available as a limited free trial during a beta phase.<\/p>\n<p>For nighttime landscapes, the app can detect the foreground and process it separately from the sky. You can then adjust how long the foreground remains frozen. This way, the stars stay sharp during tracking, while the foreground landscape remains sharp and natural. Constellation recognition displays the constellation lines and names. You can then initiate automatic tracking from this map. Star trails can be automatically converted into a video.<\/p>\n<p>An equatorial mode is also available. To use this mode, you must point the camera toward the celestial pole using a compatible tilting ball head, sold separately\u2014for example, the TH10 head, either on its own or with the TC20 tripod. According to the manufacturer, 60-second single exposures are limited to equatorial mode, once the alignment is sufficiently precise. They are not available in azimuth mode.<\/p>\n<h3>Connectivity, Battery Life, and Form Factor<\/h3>\n<p>The device connects to a phone or tablet via 2.4 or 5 GHz Wi-Fi\u2014up to 10 meters under the manufacturer\u2019s test conditions\u2014or via Bluetooth, up to 5 meters. On a compatible phone, an NFC connection is established by bringing the device close to the phone. A USB-C port is used for data transfer and charging (5 V, 3 A). A button allows you to reset the Wi-Fi.<\/p>\n<p>The built-in 6,000 mAh battery provides up to 6 hours of battery life according to the manufacturer\u2019s lab tests, at room temperature, in viewing mode. Actual battery life varies depending on temperature, active features, and usage conditions. Internal storage is 64 GB, of which approximately 45 GB is available for images and videos, with the remainder occupied by the system. Updates may affect this available space. Photos are saved in JPEG and FITS formats, and videos in MP4 or AVI. The app also allows you to enhance images with a single tap or manually adjust noise reduction, star size, brightness, contrast, saturation, cropping, and flipping.<\/p>\n<p>The device measures 210 \u00d7 140 \u00d7 80 mm when closed and weighs 1.65 kg without the tripod. The base has a 3\/8\u2033-16 thread, compatible with the included tripod or any other photographic or astronomical tripod with the same thread pitch. The specified operating range is \u221210 \u00b0C to 40 \u00b0C, with a relative humidity of 20 to 80 %. Charging must be performed between 0 \u00b0C and 40 \u00b0C.<\/p>\n<h3>Box contents<\/h3>\n<ul>\n<li>Seestar S30 Plus Telescope<\/li>\n<li>Magnetic solar filter<\/li>\n<li>Aluminum alloy tripod<\/li>\n<li>Protective case with shoulder strap<\/li>\n<li>USB-C cable<\/li>\n<li>Quick Start Guide and Safety Instructions<\/li>\n<li>Sheet of astronomy-themed stickers<\/li>\n<\/ul>\n<h3>S30 Plus, S30, and S30 Pro<\/h3>\n<p>Compared to the Seestar S30, the S30 Plus features a four-element apochromatic lens, a 160 mm telephoto focal length (compared to 150 mm), larger sensors, and 2K resolution. It also adds wide-angle photography of the Milky Way, star trails, and meteors, as well as NFC connectivity.<\/p>\n<p>The <a href=\"https:\/\/deep-space-astronomy.ch\/en\/product\/seestar-s30-pro\/\">Seestar S30 Pro<\/a> Goes even further: an 8.3-megapixel 1\/1.2-inch telephoto sensor, a 63\u00b0 wide-angle field of view, 4K output, wide-angle mosaic, Milky Way arc capture, and simultaneous shooting with both cameras. Both models share the same four-element optical design. The S30 Plus is the entry-level model of this generation. It already allows users to photograph deep-sky objects and wide-field scenes in a simpler, more accessible camera. The <a href=\"https:\/\/deep-space-astronomy.ch\/en\/product\/seestar-s50-pro-smart-telescope\/\">Seestar S50 Pro<\/a> has a 50 mm opening.<\/p>\n<h3>Technical specifications<\/h3>\n<table>\n<thead>\n<tr>\n<th>Features<\/th>\n<th>Value<\/th>\n<\/tr>\n<\/thead>\n<tbody>\n<tr>\n<td>Model<\/td>\n<td>Seestar S30 Plus<\/td>\n<\/tr>\n<tr>\n<td>Type<\/td>\n<td>All-in-One Smart Telescope with Dual Cameras<\/td>\n<\/tr>\n<tr>\n<td>Telephoto Sensor<\/td>\n<td>CMOS SC485SL, 1\/1.8-inch, 1440 \u00d7 2560, portrait orientation<\/td>\n<\/tr>\n<tr>\n<td>Wide-angle sensor<\/td>\n<td>CMOS IMX586, 1\/2 inch, 1440 \u00d7 2560 after cropping, portrait orientation<\/td>\n<\/tr>\n<tr>\n<td>Field of view<\/td>\n<td>3\u00b0 telephoto, 43.5\u00b0 wide-angle (after sensor cropping)<\/td>\n<\/tr>\n<tr>\n<td>Aperture<\/td>\n<td>30 mm telephoto lens, 3.4 mm wide-angle lens<\/td>\n<\/tr>\n<tr>\n<td>Focal length<\/td>\n<td>160 mm telephoto lens, f\/5.3; 6 mm wide-angle lens, f\/1.75<\/td>\n<\/tr>\n<tr>\n<td>Full-frame equivalent focal length<\/td>\n<td>815 mm telephoto lens, 55 mm wide-angle lens<\/td>\n<\/tr>\n<tr>\n<td>Telephoto lens<\/td>\n<td>Four-element apochromatic lens<\/td>\n<\/tr>\n<tr>\n<td>Focusing<\/td>\n<td>Telephoto: 6 m to infinity; wide-angle: 0.1 m to infinity<\/td>\n<\/tr>\n<tr>\n<td>Integrated filters<\/td>\n<td>UV\/IR-Cut (both cameras).
