Laurent has sent some images that shows the new feature he has incorporated to his telescope. It is a thermal sensor. It is used to measure accurately the temperature of the mirror and of the environment. That way he tries to avoid thermal issues in his planetary images, reducing as much as possible the gradient of temperatures between his telescope and the surrounding air. This technique has been employed to acquire the Jupiter picture we see here.
