Hi Doug,
I think the reducer is the root cause of the problem here. Reasoning; consider that the new baffle design prevents this ring reflection for the standard field. Your field is pretty extensive based on your tarantula shot. The field for M42 is quite large too. You can also see another reflection just near running man. How old is the scope? If it is the newer version, try it without the reducer first as you plan. If the reflection still appear send it back. The new versions don't have this problem with ring reflections. If you find the reflection disappears then consider the following:
1) don't use the reducer.
2) consider buying another reducer or perhaps a flattner.
3) do the flocking mod.
I would use that order of thinking too. Do the mod as a last resort.
If you do the mod be careful of alignment of the optical system. Also look out for loosening the primary when you unscrew the baffle. I did not have this problem but another chap did and the scope had to go back to GSO for alignment.
With collimation remember to collimate with the focus on the outer side of defocus. If you wind inwards you will get incorrect collimation.
Generally this is a good start and you will get the reflection nutted. Are you using the standard focusor or another unit? If you are using the standard focusor consider this also as the source of the reflection too.
Please let us know how you go with sorting the problem and feel free to ring me should you have any issues. My number is in the bulletin.
