Just out of interest how fast is your system? I am around f5.6 with the 4" and get halos on the bright stars. Do you use a fast system and do you use Astrodon filters? I am using Astronomiks which have been exchanged once already and note that your images don't have the halo problem mine sometimes do have. I wonder if it is the filters, the f ratio or if it is a combination of both.

Thanks Paul Are you using a reducer to get F5.6?
The TEC110 is F5.6 and uses a flattener as well. I find the Astrodons are quite good with reflections. Haven't much of an issue there. I generally find Astrodon overall to be of a high standard.
