Quote:I had the same problem with the ES100 14mm on my Orion XT12i: with the stock Crayford focuser totally extended, the image was still slightly out of focus. I could solve de problem by moving down a little the primary mirror tightening the collimation screws. Of course, you will need to re-collimate. Now it focuses with all my eyepieces.Best,Mingo
