Parracor question with bino

Just throwing this question out there: do I need a parracor?

I own a 12.5" f/6 dob, which of course doesn't need a parracor. However, I just order a Discovery 16" f/4.5. I once owned a 10" f/4.5, and only saw the need for a parracor on really wide fields.

I use a Denk II with a Power Switch, along with a pair of 24.5mm Meade SuperWides (old pair) and 15mm Expanses.

I'm thinking the only thing that the parracor would prove beneficial is my 35mm Pan, but aside from that it wouldn't be necessary. I'm looking for opinions on the matter.

Thanks,

Guy

With a Binoviewer I don't see any need for a Paracorr.
A 35mm Panoptic would have an improved edge with one, but not as perfect as a Nagler for instance. Shorter f/l EPs such as 14mm and below, will not show much coma and the Paracorr is not so much of an issue with them.
Even at f/6 a Paracorr will improve the edge of a 35mm wide field EP.
