Yesterday evening I corrected the settings as follows and tried to get rid of any inaccuracies:
1. The time setting was two minutes out, now it is bang on.
2. I checked alignment of my polar scope and no adjustment needed.
3. I adjusted the finderscope as it was slightly off also.
4. I believe my polar alignment was quite good as I was able to go unguided for 3-4 minutes and no movement of image nor star trails.
Now I have become aware that Cone Error is a thing, maybe that is a problem as my dovetail is not perfectly flat nor sits perfectly flat. There is room for small error there, how important might this be?
Anyway, last night I had some success for the first time since I got my mount four days ago. I slewed to Alderamin and synched to it then onto the Cave Nebula which I imaged for 3 minutes each sub. I managed to get 13 x 180s images and stacked them (I did reject a few not many). The resulting image is good and I will need much more time on the object. I am looking to get a few more hours on this tonight.
Great news! I guess you've successfully passed the "peak" of the learning curve with your mount
Now it's time to enjoy the imaging.
