I’ve had some success with brighter emission nebulae in the past, but fainter targets such as the California nebula have always remained elusive. Although perhaps not the most interesting target, it’s secretive nature hiding away in the deep end of the red wavelengths made it a fitting target for the newly modified camera.
Waiting for the moon to set at 2am, I managed to capture almost an hour of data before the local abbey striking 3am gave me the signal to pack up. The image is a little washed out due to the short exposure times and lingering moonlight, but I could only have dreamt of registering anything but a faint smudge before the upgrade.
