Celestron Ultima Eyepiece compatable with Digi-T?

Last night I had the best view of mars in the 1 month I've owned my scope. I was using my brand new Ultima 10mm eyepiece. I decided to try for a quick photo with my Canon G2 and Digi-T adapter. The digi-t was too small to fit on the 1.25" eyepiece! Has anyone else experienced this? Am I missing something? Is there a work around? I am impressed with the eyepiece for the money and was planning on adding a few more Ultimas to my collection- but if they will not work with the digi-t I might have to look at a different line.. I have used my lesser quality Celestron eyepieces and my standard Meade 26mm 4000 with no problems.
