IDAS NBZ is awesome
This filter is AMAZING! I not only will it work in a variety of configurations (it can work with a hyperstar at f/2), but it brings out the magic in any nebula. Even in a 10 second preview of the rosette nebula, you can make out the shape of the nebula! The colours are great and my final stack needs very little colour adjusting. A+ filter!
