The 27mm Pan might be the next best option if the 35mm is no good.

My thoughts are a 35 mm Pano would be ok in a 10"Dob. If you change scopes in the future say to a SCT or Refractor then the 35 is perfect.
John has explained it well above.
But a 27mm Pano or 26 Nagler would be slightly better in the Dob.
Any high end Ep's is good.
We seem to juggle high end Ep's a lot !
To me it's a matter of personal choice and finances. A second hand 27 Pano is much better on the sky rocket.
