Do you have a Seestar S30 or S30 Pro at home, or is one on your wishlist? With the right Seestar S30 accessories get more out of every clear night: more stable shots, longer exposures, and a lens that stays dry and clean. In this guide, we list the accessories that truly make a difference. For each accessory, we indicate whether it is useful for the S30, the S30 Pro, or both models, because the two differ more than you might think at first glance.
First, let's clarify: S30 or S30 Pro?
The Seestar S30 is the compact entry-level model with a dual-lens system. The Seestar S30 Pro goes a step further: a quadruplet APO main optical system, 4K sensors, an internal filter wheel with a dual-band filter, built-in dew heater, and an EQ mode with exposures up to 60 seconds. That difference also determines which accessories you need: the Pro already has a number of features built-in that you would have to buy as a separate accessory for the standard S30. Are you still hesitating between the two? Then read our first Seestar S30 Pro review.
1. A full-fledged tripod (both models)
The most important accessory is immediately the least exciting: a sturdy tripod. Every vibration your telescope picks up will show up as blurriness in your frames. The ZWO tripod for Seestar telescopes (€169) is made for exactly this series: stable in a gust of wind, at a comfortable working height and without the wobbling of a lightweight photo tripod. If you want to work on balcony tiles or a patio, this is the upgrade that will improve your shots the most.
2. The EQ Polar Wedge: longer exposures
The ZWO Seestar EQ Polar Wedge (€159) tilts your Seestar toward the celestial pole. This allows the telescope to rotate with the starry sky instead of against it, which greatly reduces field rotation. For the S30 Pro, this is the key to EQ mode with exposures of up to 60 seconds per frame: more signal, less noise, deeper nebulas. The wedge fits the S30, the S30 Pro, and the S50, so it moves with you if you upgrade later.
3. Dew and dust outside the door
In the Dutch and Belgian climate, dew is the number one session spoiler: a fogged-up lens halfway through the night and your shoot is done. The S30 Pro has built-in anti-dew heating, so a separate dew shield is rarely needed there. For the standard S30, the Omegon dew shield and dust cover for the Seestar S30 (€59.70, available in 20 mm and 30 mm versions) a wise purchase. For storage and transport, the dust cover for the S30 and S30 Pro (€19.90) a small effort that keeps your optics clean.
4. Spike masks: diffraction spikes in your photos
Those distinctive star points in astrophotographs are usually caused by the spin trails of a reflecting telescope. With the Bahtinov mask with dew shield for the Seestar S30 (€34.90) you add that same effect to your Seestar recordings. Purely aesthetic, but it instantly gives bright stars a professional look. Useful side effect: the shape of the spikes immediately shows whether your image is well-focused.
5. Light pollution filters (especially for the S30)
Living under an orange city sky, a dual-band filter is the biggest quality leap for emission nebulae. The S30 Pro already has such a filter in its internal filter wheel: so nothing extra to buy. For the standard S30, you build the same route with the Omegon S30 to M48 adapter (€19.90) plus a 2 inch M48 filter like the ZWO Duo-Band 2 inch filter. The adapter turns your S30 in a single operation into a telescope that accepts standard astro filters. Optolong's 2-inch narrowband filters also fit on that adapter; which filter belongs to which sky is listed on the Optolong merk page.
Right the first time: the Seestar S30 Bundle
If you are starting from scratch, the Seestar S30 Bundle worth considering: telescope plus the most popular accessories in one order. For those who already have a Seestar, here is some honest advice: don't buy everything at once. Start with the tripod, see for a few nights what you're missing, and then expand purposefully.
