This attractive pair are outriders to the LMC and not often imaged. This is a SII, Ha, OIII (90x90x90 in 10 min subs) at F11 in my EdgeHD 14" with an ATIK11002M with an OAG Lodestar guiding at F11 also.
Processing is just DSS for stacks and CS5 for a bit of colorizing.
Enjoy.
Interesting work, I just did a quick calculation...... You are shooting at 3900mm focal length, quite an achievement with round stars.
Query regarding the mix of wavelengths as I'm presuming the ha is the blue color? I'm not sure I can determine the other wavelengths in the image
