Un bon dossier récap sur les magnitudes en matière d'astronomie -> magnitude apparente/m, magnitude absolue/M...
Fun fact, en magnitude absolue, le soleil (M=4.83) brille bien moins que Bételgeuse (M=-5.14)... #saf #SociétéAstronomiqueDeFrance #lastronomie

On Friday evening, the weather conditions looked good, so I grabbed my Canon EOS80D and tripod and headed for a spot with 360⁰ views! At 7h30pm the comet was barely visible to the naked eye... With a magnitude of 3.8 and the full moon rising quickly, it was […]

To test my C8 Edge HD + ASI533MC Pro setup, which I hadn't used for at least 8 to 10 months 🌧️🌧️🌧️..., at the end of August, I targeted the beautiful NGC6946 for a few minutes (18x180sec) and even with so few sub's and no flats, I found the results amazing! 😍 C8 + ASI533MC Pro = 💪🏻

1/2 Le dossier que j'attendais pour faire le point sur la question des couleurs produites en imagerie du ciel profond.
@Stef_Astro Après lecture, j'ai une question... On parle de rendu LRGB mais quid d'une image issue d'une caméra OSC (avec filtre narrow band, Ha - OIII) ?

1st test, maybe a little too red... what do you think ?
NGC7635 - Bubble Nebula. 50x180sec, I think we still need a little more data...
C8 Edge HD + CEM40 + 0,7 reducer + ASI533MC Pro + L-Ultimate filter- Processing #pixinsight

The pre-processing has just finished (WBPP)... what a beautiful target ! I just love it ! ☺️
This is NGC7635 the bubble nebula. Captured on 28 September in Normandy. 50x180sec, C8 Edge HD - CEM40 mount - ASI533MC Pro #astronomy #astrophotography […]

Here's a much more acceptable HOO version! A softer picture... 😊 NGC7380 The Wizzard Nebula 🧙‍♂️
For this OSC image, I used Bill Blanchan's NarrowbandNormalization process + the Colormask_mod script (Mike Cranfield ) #pixinsight

A Hubble Palette test...😅 I'm not satisfied... Not soft enough, too bright ! I'm going to start all over again ! Sometimes you're satisfied, sometimes you're not... 🤷🏻‍♂️

The Wizard Nebula in the constellation of Cepheus. 42x300’’ Image taken with an C8 Edge HD and a iOptron CEM40 mount - ASIair plus and EAF. This nebula is located at 7500 LY from us. #astrophotography #astronomy

This is the result of a 63x30’’ capture of the Milky Way taken at Dieulefit (Drôme, south of France - 22 and 23/08) The sky over Dieulefit (Bortle4) is magnificent !
Image taken with a Canon EOS80D on à StarAdventurer GTI mount, processed via #pixinsight and […]
