A little extra info about the type of equipment used would be great.
The subs are short so it is a little difficult to see tracking error.
Keep up the good work.

Thanks Dave for the kind comment, it really was a great night for imaging
good skys here in the NT.
Equipment run down for you:
NEQ6 PRO
200mm 8 inch F/5 newton reflector
No guiding scope ..yet
No coma corrector ...yet either.
To give you a run down of the focuser setup. It goes canon <550d> <t-ring> <t-adapter 1.25"> <1.25" to 2" adapter> <2" Bintel Crayford Focuser 10:1 (2")....focus point 2.5 on side scale. The focuser/camera face downwards when facing polaris. Now how would I go about adjusting the focuser so that we could eliminate those tear drop stars.
Many thanks.
