just offhand,try (cloud permitting) offset at 50, and try 100x30sec exposures. If you can autoguide your scope, set the quality at 80% or higher, and you might have to use drizzle if you are not polar mounted. What should happen is a few exposure sequences will be discarded while the scope adjusts tracking as required, but it works fine; 70 mins to get 50mins of guided images without a dedicated guide camera is not a bad trade.
gotta go out, will catch up later

That is from memory so may not be 100% acurate.
I did a lot of stabbing at the settings that night  |
