A picture says it all... the sun is "eclipsed" by a crane from a nearby construction site! In the summer, the sun used to be in a poor location from inside my home, I can workaround this problem by using an offset plate on my LXD55, however, I found that the active construction work around my home is finally invading my indoor imaging site!
I love that long filament...!
There's a good news to me, my Autostar works again... I believe the HBX cable has some problem, maybe some bad contact somewhere.
