Description

***** ENG: from my 2019 expedition in Namibia. The "Cat's Pawn" Nebula and the "Lobster" Nebula (NGC6334 and 6357) with double tube technique. Halfa comes from the FSQ106 with SBIG11000. Color is from my Canon 60D Baader with 100-400 IS II @ roughly 250 mm. Data "fusion", as always, by the great Edoardo Radice. 20x1200s frames in Ha, 37x600s frames in color (in 2 nights). Guide provided by a rented 50/200 little guider, with my Lodestar.

The difference from my first try (image "C") and the final processing by Edoardo is a powerful reminder of HOW MUCH of a good astrophoto is postprocessing.

SQM 22,0 and more, Bortle 1 - yes, this is the regular sky at Tivoli!

***** ITA: dalla mia missione "Namibia 2019". Le nebulose "orme di gatto" e "aragosta" (NGC6334 e 6557) riprese con Takahashi FSQ106 con SBIG11000 (in Halfa) e Canon 60D Baader con tele Canon 100-400 IS II a circa 250 mm di focale. La fusione dei dati colore è del solito bravissimo Edoardo Radice. 20 frame da 20' per l'Halfa, 37 frame da 10' per il colore. Guida con un piccolo 50/200 affittato e la mia Lodestar.

La differenza tra quella che io consideravo una discreta elaborazione (immagine "C") e la versione finale di Edoardo dimostra in maniera lampante quanto sia importante il postprocessing nelle immagini astronomiche.
