Viewing Mars, Extra Disk--The Eyepiece Factor

Viewing Mars with the Meade 25mm provided eyepiece with the LXD55 AR6 gives something like two
disks, one brighter than the other. I've seen this before with SCTs and other scopes. Possibly it
has something to do with the brightness of Mars. I've seen it with Jupiter. I've been told that the
effect is reduced by using shorter length eyepieces. I noticed this effect with an 11" C-11 f/10
last night and going to a Televue 9mm eyepiece helped somewhat. I'll try it on the AR6 tonight. Any
thoughts on this? Maybe a Barlow would reduce the extra circular glare?
