Due to some troubles with the filter wheel it was not possible to do a deeper picture with this rig.
It’s only 28 hours (latest objects on my list are about 60 hours each) but seems enough integration to provide good details on these Ha clouds.
It’s a nice object that I revisited after more than two years, with new equipment, techniques and personal tastes…. I like to see my evolution
