Feedback on turrets?Posted By James Brown |
I can detect no optical difference at all between my TEC turret and my Televue diagonal (dielectric coating version). This is with a TEC APO 140 (f7).
The turret is a breeze to use. One "bonus" benefit of the turret is that the indexing mechanism unlocks so that the active eyepiece can be rotated to whatever position is best for comfort. This is nice when compared to a regular diagonal, because there is no risk of dropping everything upon loosening the diagonal set screw. It works like a camera angle adjuster.
The quick magnification adjustment and "eyepiece angle adjustment" capacities of the TEC turret make it great for use sharing the telescope with kids or novices. It is a beautifully machined piece of equipment too.
If I had to point out a downside, the only thing I can think of is that the fully loaded turret is heavy. It is hard or impossible to properly balance a short telescope like my Sky 90 with the turret in place. Also it would not work at all with a Newtonian, unless you are a contortionist! I live in a dry climate so eyepiece dew is almost never a problem.
