voitty,
You seem to have a misaligned secondary mirror and a well aligned primary mirror. In this case, the film canister will give good results but the laser will not. The laser collimator is sensitive to both the secondary and primary alignments.
Try the following:
1- Adjust the secondary mirror to redirect the forward laser beam to the dead center of the primary mirror spot. This is an important step. Do take your time to ensure the forward laser beam is centered. If there is too much laser glow, shining a flash light on the primary mirror will reduce the laser glow.
2- Adjust the primary mirror to ensure the returning laser beam retraces its path all the way back to the source.
3- Do NOT alter the OTA ALT angle. Remove the laser collimator and insert the film canister. Does it agree with the laser now?
