The C/2023 A3 Tsuchinshan-Atlas comet, as seen from Barcelona through a 4 cm telescope in a 5-minute exposure. Field of view is 11°x7°, meaning, the tail is huge! This is one of the very few comets that has developed an anti-tail, made of the heavier dust particles that are immune to the solar-wind push (https://lnkd.in/diFGXb7C). In the photo, you can see the anti-tail as a spike in front of the comet's coma.

This Hubble Telescope image showcases the visually striking nebula RCW 7, located over 5,300 light-years away in the constellation Puppis.Nebulae are areas rich in the raw material needed to form new stars. Under the influence of gravity, parts of these molecular clouds collapse until they coalesce into very young, developing stars, called protostars, continue... https://lnkd.in/guSErNtH

🔆〰 Light is energy and can take many forms. Colors are merely the way our brain interpret the wavelength of light. However, the human eye can only see one tenth of a billion of the electromagnetic spectrum, which ranges from radio waves to gamma rays. Many insects can see ultraviolets, while some fish, reptiles, and amphibians can see infrared radiation. There's a whole world around us that simply isn't within reach of our eyes, but the same cannot be said of our intellect: just consider the applications of X-rays or UV radiation, for example, or how the James Webb Space Telescope has revolutionized the image we have of the universe by recording it with its Near-Infrared Camera (NIRCam) 🔭🪐✨ www.arquiled.com #Arquiled #constructelvisabeira

With revised technique and calculations, I found that the faintest star visible in this frame is of magnitude 13.8 (see comment below). So I reasonably estimated the debris streak at 1 magnitude fainter. Had the telescope been tracking the debris, it would have stayed on one (binned) pixel in the 200ms exposure, appearing as an object of magnitude 9 (calculated separately/updated), giving it a size of approximately 10-11cm at its calculated altitude of 445km (calculated from the length of the streak against the FOV and exposure). This is fairly close to our target of achieving detection of 10cm or smaller LEO objects.

The Moon was low in the south west. it was too low for my telescope, so I used my DSLR at 300mm focal length, ISO 100 and 1/500 second exposure. https://lnkd.in/eT-remav
