La piccola nebulosa oscura vdB 142, detta anche "proboscide di elefante", immersa nel complesso nebulare IC 1396, nei pressi della costellazione di Cefeo, costellazione circumpolare alle nostre latitudini, e quindi visibile tutto l'anno. L'immagine è stata ottenuta con la camera di ripresa ASI 183 MC-Pro su Celestron RASA 8" (400mm di focale a f/2). Sono state effettuate 35 riprese da 5 minuti ciascuna con filtro a doppia banda stretta (Ha e OIII) e 25 pose da 30 secondi ciascuna con filtro anti inquinamento L-Pro. La ripresa a banda stretta evidenzia le zone nebulari prodotte da emissioni di idrogeno e ossigeno ionizzato sulle quali si stagliano le polveri oscure, la ripresa in banda larga invece permette di recuperare il normale colore delle stelle che in genere viene meno nelle riprese in banda stretta. L'elaborazione è stata effettuata in HOO palette, (Ha sul canale rosso, e due differenti miscele di Ha e OIII sui canali verde e blu), tutto eseguito su PixInsight e Photoshop.
