Starter scope for narrowband?
I'm starting to think a little more about trying some narrowband imaging from suburban Melbourne. I wonder if I could ask for a few pointers? I have an NEQ6, and I'm just looking for info on suitable OTA's, not cameras.
I'm thinking about a Saxon/skywatcher level refractor.
1. What aperture/focal length is recommended for beginners?
2. Is it true that an achromatic refractor is adequate for narrowband?
3. Are there any "tried and true" options?
Cheers
Stephen
