Do you actually recenter the object at the center of the field of view of the eyepiece?  Or do you place the object at the edge of field of view, and let it drift all the way across?  That's the way to do it.

At the edge, as you describe, allowing more drift time. My original description was imprecise. Having eyepieces that are sharp to the edge help here.

Some of the best views I got of Mars last summer and fall when the skies were steady, we’re through a NP127 that you are familiar with, and 3.7 or 4.7 ethos eyepieces in the diagonal.

Im very glad to hear that from you. The 3.7 comes in today.

I use the Ethos 3.7 with my NP127is on planets (and sometimes on Globulars and planetary nebulae).

 

I find the sharpness to be excellent, and I've had wonderful views of Jupiter these last few months. 

 

I do notice some issue with contrast when the planet is dead center in the eyepiece.  There are some internal reflections happening. 

 

I do wonder if a Powermate + longer focal length Ethos might spread any reflections over a larger area.  I also think I'd like more than the 178x magnification given by the 3.7 Ethos.
