got tube slop/tilt

The lock screw is countered at 180° by the hexagon head tension screw. If you want to use the lock, make sure you have sufficient tension to minimise movement but remember to loosen the lateral parallel-ising screws to either side first as well as the locking screw at 90° beforehand, as well as removing the flexible (sic) o-washers from the corner retaining screws.

Whilst you're there, you may want to reseat the brushed aluminium collar. There are three grub screws. Loosen, shake/twist and tighten each with the telescope objective pointing downward gradually until home.

The combination above should get you -and keep you- as square as SkyWatcher allow.

I appreciate your help but this doesn't sound like something I want to attempt just yet. Good chance I'll make things worse

If clear tonight, I'll have another go and see if having the locking bolt loose works again.

Still trying to work out if the data I got last night is worthy of being joined with my previous data. Then I'll double check tilt/slop in the results. Maybe subs too?

this is close enough to not worry too much about?

stacked result

 

some random subs after i loosened the bolt right off.

Hi
It would be very difficult for us to say without having seen the image which was produced as a result.
My advice would be to always look at the final images. Never the numbers. Then, and only then, decide whether you  think it's OK.
You're doing great.
Cheers

ill do a quick process on the stack image just from last night. soon as i get a chance. i appreciate the encouragement. 

ok below is a process of all the half decent and better subs from last night. just a quick stretch, no starnet, no crop, etc also same version but with the sensor tilt estimator thingy showing. i think there is a slight eggyness in the bottom right had side, but i'd be happy if it stayed consistently like this. i think.
