Come sempre una cometa è un "evento astrofotografico" raro e come tale molto emozionante. Le comete sono oggetti affascinanti e molto particolari da fotografare e soprattutto elaborare perché come si sa "si muovono" tra le stelle ! Questa mattina quindi mi sono alzato verso le 4, mi sono recato nel mio balcone dove avevo già sistemato il mio telescopio e dopo averla inquadrata ho iniziato a scattare foto a questa bellissima cometa, la C/2025 A6 Lemmon ! Ho utilizzato il mio RC da 8 pollici che con i suoi 1624 mm di lunghezza focale non mi ha permesso di riprendere tutta la coda della cometa che sembra essere davvero molto lunga. Ho ripreso per poco più di un'ora con scatti da 1 minuto e sono molto contento del risultato ottenuto. Se in futuro ricapiterà l'occasione cercherò di fotografarla con una focale più corta.

Wonderful congratulations! here at my place bad sky... :-/
P.S. To process it, do you use PI's classic CometAlignment process and remove the stars from those of the comet?

Thanks :)
I did this tutorial a few years ago:
I use method 1, first I create the star mask (one per RGB channel) then I align the individual recorded ones by subtracting the respective star mask.
I therefore find the comet "alone" in which to add the stars of the 3 masks of stars. With an OSC you clearly do it first.

Nice image, congratulations.
But there is only Pix to process stars and comet?... I tried DSS but it never worked. :-(

Thank you GP. I have always used pix and never tried other methods but I am more than convinced that there are also other ways, probably not free but there are certainly some.
