A quite nice environnement but even with 35mn exposure, its was hard to get with the proximity of the moon and only 26° above the horizon in Chili. An nice object for the next days for the observers in the North.

Bonjour

Voici le spectre de 2025rbs que nous avons réalisé pendant le camp AstroMaths avec les jeunes.

Hi,

One month later, the supernova is still clearly visible in the galaxy NGC7331.

I tried to obtain a color image with the RAPAS filters using SiriL’s “RGB Composition” feature.
