What about the ( unavailable!) Pretoria eyepiece Ex-UO or the Klee Barlow.
I'm using a 49mm field flatner lens ( can't remember where it came from, TV or Lumicon?) seems to be OK.
With the HUtech filters, which one is recommended for DSO photos????

Hi Merlin66(i'm sure we have met before
)
The TV Paracorr is very good and very expensive. My friend uses one in his 18". I can't see a big difference, but it is there and we use high end EP's which helps. I have been meaning to use it in my 10" I have not as yet.
I had a klee barlow and now I have the 2" UO Barlow. Both are very good.
I would recomend either.
I reviewed the 2" Barlow here
