The next eshine telescope

When danish ESA astronaut Andreas Mogensen goes to the ISS in August 2023, he will be performing science experiments for a number of groups. We are one of the groups and have suggested that images of the New Moon be obtained in order to evaluate how much scattered light is avoided when imaging the Moon from above the atmosphere.

Comparing to images taken at the same time through the atmosphere will constitute the Earth-leg of this experiment, conducted by astronomers and interested people with a camera. Communication about this possibility will be conducted through the dmi.dk site and on social media platforms.

Public images posted along with the hashtags #newmoonsnap and #huginn will be collected and evaluated. With ESA it is hoped to make the experiment international.

Some CCDs are not 2-dimensional, but are just a single line of sensors. Typically used for scanning devices. Here is one such. Another is here.

The first one appears to be 16 bit – but what is the readout noise, and can you get line CCDs with better than 16 bit dynamic range? Second one is an 11ish bit device?

There is a type of camera where the sensor reacts to changes, not to ‘an exposure signal’. The DAVIS 346 Neuromorphic camera is one such.

Note the apparent high dynamic range of 120dB – like a 100-image stack from MLO?

How can we use an ‘event-based camera’? Can the camera also be triggered from outside?
