Luckily for me Mark, I'd already bought an FLI 2-5 filter wheel for my Orion, and Astrodon Narrowband filters... Whilst these were overkill for the Orion camera, I knew I wanted to do narrowband imaging, and I knew eventually I'd get a large sensor monochrome camera... The camera just came sooner rather than later... Normally I would have been more hesitant on new gear, but its an SBIG... I trust they've got everything right!
