Hi Tom
I have tried this a couple of times with an unmodified Canon 30d and a skywatcher ED102 with a HEQ5 mount, as well as a TAK FS60
1st Attempt
These were 5 * 15 minutes subs from North Sydney, RGB.
Nebula NGC6188 and Cluster NGC6193
2nd attempt
Again, from North Sydney though this time a lot more data, 61 subs of 6 minutes and with a Tak FS60. Issue here was field curvature but it shows NGC6164/5 (just)
NGC6188 and 6193
Its doable but darker skies would be better and processing skills need a bit of work
