Any one experiencing same halo issue when using L extreme? I also found bright star on the left always had this offcenter halo. There also a bunch of small orange star that had halo while other star around doesn’t had. Is this all normal? I attached stacked photo with only BGE and autostretch.

My setup is Skyrover 90SAP + Filter Wheel + QHY268C

It is normal for refractors and leaky cameras in the IR. L-Extreme also leaks in the IR so there you are, halos.
