The Iris Nebula, NGC 7023 1841 viewsLocated in Cepheus, this blue reflection nebula is dominated by a 7th magnitude star at its centre. Because it is predominately a reflection nebula, an OIII filter was not appropriate so instead I combined the usual H-alpha (2 hours) with a standard blue filter (2 hours).
