Hi: A couple of years ago I bought a WO ZS 66SD to replace my Pronto as I was getting frustrated with the chromatic aberration in my bird photos. I have only recently gotten the 66SD properly balanced on it's mount and I am beginning to enjoy the views.
I am using the stock 1.25 inch dielectric diagonal which makes for a handy scope but I am contemplating acquiring a 2 inch SCT diagonal so that I can use 2 inch eyepieces. The clear aperture of the drawtube is about 42mm, probably adequate for a 35mm pan with its 38.7mm field stop. This would provide a generous 5.7 degree TFoV.
So, I am looking for others who have tried this, thoughts, experiences, recommendations, what can you tell me?
Thanks
jon
