On this page, you will find a variety of tutorials for Hestia and its Gravity app.
These tutorials cover a range of topics to help you properly set up your Hestia and perform both day and night observations.
It is essential to maintain the best possible alignment to ensure optimal quality photos.
For installation in daytime or in the early evening, please refer to the "Daytime installation" video.

ISO in photography indicates the camera's sensitivity to light. High ISO allows you to take photos in the dark, but can add grain to the image. Low ISO gives sharper photos for daylight shots when light is abundant.
Exposure time defines how long the camera lets light in. With a long exposure time, the image may become blurred and take time to appear.
To observe the stars, you should choose the maximum value.
Short exposure times freeze the action and produce sharp images, but they need more light.
Use the focus ring to adjust focus according to object distance.
If the sharpest position is at the end points, you need to turn the focus ring: unscrew it if the slider is at 0%, tighten it if it's at 100%.
During the day, you can choose to switch back to automatic focus once the ring position is correct. Otherwise, proceed to the next step.
Solar observation must be carried out with Vaonis solar filters. Never look directly at the sun without the filter, as this could injure you or damage your phone.
The image will turn black, with only the sun remaining visible after the filter is installed.
⚠ Never look directly at the sun with your naked eyes, as it can cause serious damage to your vision.
⚠ Avoid moving Hestia during this step to prevent blurred images.
By default, Gravity displays a round image that corresponds to the maximum view with Hestia, but you can choose a different frame.
