Description

***** ENG: from my 2019 expedition in Namibia. The Whitch Head Nebula (IC2118) with double tube technique. Luminance comes from the FSQ106 with SBIG11000, used with L filter. Color is from my Canon 60D Baader with 100-400 IS II @ roughly 250 mm. Data "fusion", as always, by the great Edoardo Radice. 11x1200s frames in Ha, 37x600s frames in color (in 2 nights). Guide provided by a rented 50/200 little guider, with my Lodestar.

Final touch of postprocessing using Topaz denoise AI. The original luminance had a lot of problems - little motion blur, horrible reflexes from Rigel. Edo solved them all!

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

***** ITA: dalla mia missione "Namibia 2019". La nebulosa "testa di strega", IC2118, ripresa con Takahashi FSQ106 con SBIG11000 (in Luminanza) 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. 11 frame da 20' per l'Halfa, 37 frame da 10' per il colore. Guida con un piccolo 50/200 affittato e la mia Lodestar.

Tocco finale dell'elaborazione con Topaz AI denoiser. Le immagini originali avevano un sacco di problemi. Un leggero mosso la luminanza, riflessi da Rigel entrambe. Edo ha sistemato tutto!
