I used my 130 photoline TS Refractor with the new/old TS field flattener and the L-enhance filter on Thors helmet for 1.5 hour exposure last night.
what surprised me was the amount of dust in the red channel. That L-enhance really pulls out the H-Alpha in pictures I'm very surprised.
A slightly different version using the dual channel mode (HA in red O2 in blue and green, i used APP to extract the o2 and HA then combined them in photoshop, a lot more work but still a work in progress.
