Fast Dobbie ParaCor/Pretoria/Klee

[Merlin66 (Ken)]

Anyone have experience with the TV Paracorr to reduce coma in fast systems?
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????

Dave47Tuc can tell you about the UO 2 inch barlow if that helps ?

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

I have heard that the klee is somewhat restricted in maximum field available, something like 19mm aperture if memory serves ?

There's a review of the 2.8x klee barlow here.

i was looking into a parcor at one stage (till i found out how much they cost!) but realised that it was just the EP lettig the system down
