Stars blurred only on the right hand side
I’ve just noticed last night and tonight that my stars are “blurred”only on one side , the other half is ok
My 6” f6 reflector collimated ok with Orion laser collimator ( I’ve done this hundreds of times before )
Checked my focus with BYEOS ( FWHM ) focus looks ok but stars blurred on one side only
Checked my sidereal tracking both with EQMOD on the laptop and my Synscan handcontroller , Stars still blurred on one side only using both methods
Tried unguided 5 sec, 20sec and 50 sec exposures , stars still blurred only on one side
Tried PHD2 guided 60 sec, 120sec , 240 sec , 300 sec exposures , stars still blurred only on one side
Pulled the DSLR out of the focuser and reinstalled again to confirm sitting hard against focuser and tight
Obviously the larger Stars are more noticeable than the small ones
Haven’t pulled the rig apart yet as I will wait for your comments and advice
Any ideas why the stars are blurred on the right hand side ??
This is the first time it’s happened to me after nearly a year using this rig
Very strange ?
Thanks in advance
