DSLR Narrowband (6nm Ha) Test

Always curious how well can a DSLR do with a narrowband filter.

This is from a single 1200s expo. With Canon t3i + 6nm Ha filter.

Setup:

The second expo touchess the roof ;-)

Non process version ...

This is my first time viewing occultation !! Happened at 19:06 and I did see it via my 70x15 bino.
