Eta C in IR Cut
First pix from the cooled 450D in full spectrum with just an IR Filter on the nosepiece.
64 frames @ ISO 1600 taken @ about 5*C.
Not 100% sure about focus although it was as low as the BYE meter indicated but the IR component may be affecting it.
Sensor needs a good clean and I was having dew problems inside the camera but it is starting to show promise, a lot more defined and extensive Ha data.
