Hi all, here is my latest image in narrowband, the Helix Nebula. Taken with the LX200R 12", DSI II using a f/3.3 FR with 13nm Ha, OIII and SII filters.
This image consists of 60 x 30 second subs in each of Ha, OIII and SII.
They were individually combined with DSS and then a final combination in MaximDL. There was also a bit of tweaking in Paint Shop Pro to bring it out a bit more.
Cheers and all comments welcome.
