Description

My first attempt at Ha-imaging. I did not use a reducer this time. The images were collected during three nights, 14th, 15th and 16th of April., the nights are already so short here in Sweden, so not so many hours as i wished to collect. Very unusual here to have so many clear nights one after another. So wonderful to leave the equipment on place (so hard to have to carry everything inside every night:-)
