Questa è SH2-132, la Nebulosa Leone. Anche lei è ad emissione e si trova nel Cefeo. E' una nebulosa molto estesa e infatti con campo inquadrato dal mio setup non potevo contenerla tutta intera. A differenza di altre nebulose "facili" in questa ho dovuto integrare più del normale per tirare fuori specialmente le emissioni di ossigeno oltre che di zolfo perché anche in questo caso oltre ad una classica HOO volevo realizzare una versione con palette SHO per evidenziare meglio le bellissime strutture al suo interno. Ho integrato un'ora di RGB con pose molto brevi (30 secondi) per colorare le stelle mentre ho integrato 3 ore e mezzo per idrogeno e zolfo e 4 ore e mezzo per l'ossigeno per un totale nella versione SHO di oltre 13 ore (9 ore per l'HOO). Ho commesso la leggerezza di sopravvalutare il newton facendo pose molto brevi (180 secondi) per la banda stretta ma oggettivamente l'oggetto, piuttosto debole, meritava pose molto più lunghe. Tecnosky 200/800 F4 Newton Astrograph Carbon Series con ASI2600mm su AM5N via ASIAIR+.
