Description

PK 124+10.1 is a really faint planetary nebula (or SNR, I'm not sure) in Cassiopea. Night-long exposure in H-alfa for my friend Piero Mazza, who observed this nebula with his 60cm Dobson and asked for a photo. Since this nebula is visible with a big scope, I think it has a significant OIII component. Image heavly cropped and collected in binning 2. SQM around 20,1, Bortle 5. Will try the OIII component another day.

PK 124+10.1 è una debolissima planetaria (o un residuo di supernova, ho trovato fonti contrastanti) in Cassiopea. Esposizione "tutta notte" per l'amico Piero Mazza, che l'ha osservata col suo 60 e voleva una foto. In realtà la voleva a colori, ma vista la debolezza ho cominciato con l'Halfa. Dato che la nebulosa è accessibile visualmente, immagino abbia una forte componente OIII, o non vedo come sia possibile °_° Immagine ripresa sotto un cielo mediocre (SQM circa 20,1, Bortle 5). Immagine croppata pesantemente, ripresa in binning 2.
