You were right Ray, it wasn't fully illuminated an it was still leaving an odd shape to my stars, so I took everything out of the OTA agian, spider, primary mirror, secondary mirror etc...
From a bare tube, I centred the spider in the OTA, attached the secondary mirror and blocking the reflections with blue cardboard and a box blocking the rear view out the tube. Centred the Secondary mirror using a 100mm 2" extension tube and site tube in the focuser, this allowed me to get the edge very close to the secondary mirror with only a small amount of the blue cardboard showing. Once happy with that, I screwed the primary mirror cell back on, forgetting to take the box out of the tube, disassembled box and removed through the front of the OTA, carefully not touching the mirror. Checked the view through the focuser, looked ok... Put the cheshire into the focuser and aligned the centre of the primary mirror with the cross on the cheshire. Locked down the secondary mirror screws. Adjusted the cheshire black dot until it was centred in the primary mirror centre spot. Rechecked everything and tightened up the Primary mirror locking screws so they were finger tight. Re-checked the view, looked ok still.... Did I miss anything?!?!? FINGERS CROSSED! Must admit it does look much better, like what it is meant to... but the test on the stars has to be done yet...
