My eyepieces are made from the waste product of exploding stars.

Quote:At setting 5 the Paracorr lens is two inches from the top. My 20mm ES100° has a one and a half inch insertion leaving one half inch of clearance. If one has been viewing using an eyepiece that requires a lower setting something interesting happens. Placing the 20mm ES into the Paracorr and then changing the setting to 5 results in the compression of air between the Paracorr top lens and the ES field lens. Is that what you are noticing? The solution is to set the Paracorr before inserting the eyepiece.

Quote:I think my ES 20 mm 100 degree 2 inch eyepiece hits the Paracorr 1 lens at setting 5. Anybody else? Recommendations?Maybe add a 2 inch O-ring to the eyepiece?Andy
