Here my interpretation of this very low contrast nebula: I'm planning to get some H alpha data to improve the nebula visibility.

Unfortunately very thin, high altitude veils have inflated star halos.

Ecco la mia interpretazione di questa nebulosa a bassissimo contrasto: Sto pensando di acquisire riprese in H alfa per migliorare la visibilità nebulosa.

Purtroppo veli di alta quota molto sottili, hanno gonfiato gli aloni delle stelle più luminose.
