Box nebula

Hi all, Got my off axis guider working last night with the 14" SCT at F10 pointed at the Box nebula, (NGC 6309) in Ophiuchus. It is 0.3' x0.3' Magnitude 10.8 . I did a quick search on the web, but couldn't find any deeper images. This one does show a faint hint of 2 extentions out at 2 and 8 O'clock. Would be interested to see what others can record.

This is only 9x6 minute exposures with Astro 40D at ISO 800.
