ZWO Seestar S30 Plus – the new way into astrophotography

The Seestar S30 Plus fills the gap between the Seestar S30 and the S30 Pro. It adopts the high-quality four-element optics of the S30 Pro and, compared with the S30, offers a larger sensor, higher resolution and a wider field of view – at an attractive price.

Operation could hardly be simpler: set up the Seestar and tap an object from over 80,000 celestial objects in the app – the telescope aligns itself, slews to the target, focuses, tracks and automatically stacks the individual frames into an ever more detailed image. Within minutes, nebulae, galaxies and star clusters invisible to the naked eye appear on your screen.

Apochromatic optics

The telephoto optics with 30 mm aperture and 160 mm focal length consist of four elements and are apochromatically corrected – stars appear sharp and free of colour fringes. Thanks to the folded light path, the housing stays very compact. The 3° field of view (around 6 full Moon diameters) is particularly suited to large nebulae, star clusters and bright galaxies.

Two cameras

The telephoto camera with a 1/1.8" sensor (3.68 MP) captures images in 2K resolution (2560 × 1440 pixels). The wide-angle camera (1/2" sensor, 43.5° field of view) shows the sky at a glance – ideal for the Milky Way, constellations, star trails, meteors and time-lapses, with landscape in the foreground if you like.

Filters for city and countryside

• UV/IR cut filter for natural colours on star clusters, galaxies, the Moon and landscapes
• Hα + O III dual narrowband filter for emission nebulae – even under urban skies and in moonlight
• Dark filter for automatic noise correction

Alt-azimuth or equatorial

In normal use the Seestar stands level and sets itself up. For longer exposures it can be operated equatorially in EQ mode, allowing single exposures of up to 60 seconds – particularly beneficial for faint objects. In normal alt-azimuth operation we recommend single exposures of around 10 seconds – for good results with few rejected frames. For EQ mode, ZWO recommends the TH10 tilt head with the TC20 tripod.

App & automation

• GoTo to over 80,000 objects, constellations are recognised and labelled
• Plan mode and Auto Plan: schedule imaging in advance – the Seestar works on its own
• Mosaics with the telephoto camera for large objects
• Solar System mode for the Sun* and Moon, scenery mode for nature observation by day
• Image processing: one-tap enhancement, star reduction or removal, noise reduction (no AI-generated content), brightness, contrast, colour
• Remote control via the Seestar network
• Raw data as FITS for your own processing

Solar observing

With the supplied magnetic solar filter, the Seestar captures sunspots and solar eclipses.

!!! SAFETY WARNING: ALWAYS attach the solar filter BEFORE the Seestar is pointed at the Sun, and only remove it once the telescope has been turned away from the Sun. Without the filter, the concentrated sunlight can destroy the sensor instantly! Check the filter for damage before every use.

The solar filter is intended exclusively for photographic imaging with the Seestar. Never look at the Sun without a tested solar filter – neither with the naked eye nor through any optical instrument. For your own observing, please use certified eclipse glasses or Baader AstroSolar solar filter film.

S30, S30 Plus or S30 Pro?

Our recommendation: the S30 Plus is the ideal entry point for anyone who wants deep-sky and wide-field images without much post-processing. If you want the highest resolution, a wider field of view and Milky Way panoramas, choose the Seestar S30 Pro.

Good to know

• The Seestar is a purely photographic telescope – the image appears on your smartphone or tablet; there is no eyepiece.
• The 60-second exposures are only possible in EQ mode; in normal alt-azimuth operation we recommend around 10 s for good results with few rejected frames. EQ mode requires precise alignment with the celestial pole.
• With its 30 mm aperture, the Seestar shows above all the large, bright objects of the sky beautifully. It is of limited use for planets, which appear very small at 160 mm focal length.
• The telephoto and wide-angle cameras cannot capture simultaneously; mosaics with the telephoto camera only.
• Operating range -10 °C to +40 °C. Continuous use, a permanent phone connection or an active anti-dew heater shorten battery life.
• The supplied aluminium tripod is a small table-top tripod. When the Seestar is tilted in EQ mode, one tripod leg must be directly beneath the telescope – if the tilt points into the gap between two legs, the tripod can tip over!
