Thanks for that Ross

Had some O3 data which was taken on a hot night, slightly out of focus, shorter than the Ha and just generally fairly bad. But thought i would have a go at making a bi colour nb image - my first of hopefully many.

used DSS to intersect and create the green channel from Ha and O3.
Then added a mono version of Ha to the red and a mono version of O3 to blue in photoshop. i had to move, rotate and warp to align the pics to the green.

experimented with attempting to remove the stars and reducing their size but the out of focus O3 was too much of a problem for my skills. this probably would have worked better if i did it wit the original O3 file before mixing with the Ha to make green ...

anyway my first nb bicolour - it seems to have worked somewhat

Normalish with no star reduction (edit: now see something had happened with flickr darkening the 32bit format ...)
