Sooooo mmuch detail - I've imaged this myself in Ha before but boy, what a difference Aperture makes!
Mike mentioned the river, which I think is the signature element of theis DSO, but have a good look at the detail in the shock front/cliff face at the head of it - crikey!
Yep, a tad noisy but jeepers, that's a cracker of an image
Trish and I spent all day measuring voltages, measuring resistances, checking cables, comparing with the microcontroller code, getting nonsensical and non-reproducible results. Eventually we discovered the mechanical linkage between the lower shutter and the precision potentiometer was slipping unpredictably. D'oh. It explained everything. Took 5 minutes to fix.
Oh well, that's a good outcome. Still have one to celebrate.
WOW! How good is this image!
