Guiding in Maxim DL with a Finderscope Guider

At last my guiding seems to be working, after using a finder guider for a couple of years with mixed results, I think I have it cracked.

I originally used to expose my QHY5 camera on my Skywatcher finderscope every 2 seconds for guiding, and have aggressiveness setting of 4-5. I also used to use my finderguider un-binned with a calibration time of 25 seconds.

This is now my Maxim DL autoguiding set-up:

2x Binned QHY5 camera
5 second exposures
Aggressiveness of 6 and 6.5
Calibration Time: 40 seconds
Waiting time between frames: 65 seconds

These are the settings when imaging through my Altair Astro 80mm Triplet at f4.8 at 3.46 arc seconds per pixel. These settings may change when I image with my 8″ RC scope.
