Here the latest result o the collaboration between me and Luigi Fontana :
H alpha enhanced M101
The RGB signal was caught by Luigi with his ODK 12" and an unmodified Canon 6D
Since the unmodified Canon is nearly blind to hydrogen like I've added the H alpha signal, caught with a Williams Optics FLT 110 with my SBIG ST2000XM and a Baader H alpha filter.
The composition was performed according to my latest tutorial
Version B Is the Annotated version with the PGC Galaxies
Version C Is the screenshot of the PixInsight Workspace at the end of processing with the full set of Icons used for procesing.
Ecco l'ultimissimo risultato della collaborazione con Luigi Fontana.
M101 integrata da H alfa
Il segnale RGB è stato acquisito da Luigi con una Canon 6D sul suo ODK da 12".
Dal momento che la Canon è praticamente cieca alle frequenze dell'Idrogeno, ho integrato l'immagine col segnale H alfa acquisito con la camera SBIG ST2000XM sul mio Williams Optics FLT 110 con un filtro H alfa Baader.
La composizione è stata eseguita seguendo il mio ultimo tutorial
Versione B: Versione annotata con le galassie PGC
Versione C: Uno screehshot del workspace di PixInsight con tutte le icone di processo utilizzate.
