I decided to take the opportunity while the moon is around to bolt my guide setup on top of my 9.25 SCT and do some guiding tests. To aid the short focal length guider I also added a .63 focal reducer to bring the focal length of the SCT down to a more palatable 1500mm. Still a stretch for a 400mm guider but that was what the test set out to prove. So here is my result ;

Celestron C9.25 w/ 0.63 focal reducer
60 x 180sec subs + 10 darks
Canon 350d astromodified @ iso 800
STC Duo Filter
Sky-Watcher 80/400 guide scope w/ Nexguide SAG
HEQ5 pro
Bortle 8 skies w/ 98% moon
