low power 1.25'' wide field

Hi, I would like some input about what kind of 1.25'' wide field eyepiece at low power I should get for a short tube scope (I newly acquired a meade etx60 as a gadget). All my scopes are f/5. My next higher power ep is a Celestron Axiom 19mm (70*).

Candidates:
KK Magellan Widescan III 20mm (84*)
Televue Panoptic 24mm (68*) [and 22mm]
Antares Wide Field 25mm (67*)
Speers-Waler 24mm (67*)
Meade Super Wide 24mm (67*)
Celestron Axiom 23mm (70*)

Your suggestion? And if you have one available, post your price and condition.

I have a 19mm Panoptic that I use in my 10" f/4.7 Newtonian.
I have tried lower power eyepieces and most of them are not as sharp to the edge. I was going to go with the 22mm Panoptic, but I like the darker sky backround and slightly higher maginification of a 20 or 19mm widefield eyepiece for hunting DSOs.

I have never tried any of the other eyepieces that you listed. I have heard nothing negative about the 24mm Panoptic, other than the price $$$$$. My 19 I got at the NEAF brand new for $220.00.

Cameron,
The only eyepieces you have listed that will be sharp to the edge in your F-5 scope will be the panoptics based upon my experience with some of the eyepieces on your list and reviews on the others.

Rod is right. I have looked through an SWA and a Widescan III - they suffer from off-axis astigmatism in fast scopes (stars appear as "seagull" towards the edge of the field). The Panoptic does not have this problem. I haven't used the Axiom or Antares, but have read reports that they also suffer in fast scopes. I have heard that the Speers-Waler actually does pretty well (but not seen one myself). The other ones you haven't listed would be a Pentax XL 21 or XW 20, both of which will be able to handle the fast optics, but are quite pricey.

Hope this helps,

Jarad
