The Bahtinov mask is named after the inventor Pavel Bahtinov. This focussing aid enables clear focusing of astro images in the focus of your telescope or with a camera lens.
Place the mask on the telescope and point it at a bright star.
Switch on the camera and observe the constellation on Live View or on the computer.
f the image is not exactly sharp, the centre line is shifted. Adjust the focuser until the central line runs exactly through the centre of the star.
You have now achieved optimum sharpness. Remove the mask from the telescope again and you can start exposing the image.
Use the GoTo system of your ZWO Seestar S50 Smart telescope to enjoy visual observation of the night sky with optical finders on large, bright deep-sky objects or the moon, as well as the planets and their moons.
With this cable guide and strain relief, the connectors of all ZWO cameras with a diameter of 78 mm are relieved, thus avoiding loose contacts or breaks at the connectors.
Suitable for cooled cameras from ZWO with 78 mm body diameter
Light plastic design
Due to the use of PETG for 3D printing usable up to 80 °C
Dew is often a real problem on clear nights. After just a few hours, the optics start to fog up, making observation or photography impossible. A good dew cap reduces the risk of fogging and thus extends the observation time.
The spirit level on the Seestar is built into the centre of the tripod, directly under the tripod head. This is impractical, as the Seestar is only screwed on afterwards. When screwing it in, it is very easy to misalign the balancing.
