I piggybacked my Williams Optics GT71 on my ED127 and picked up an Astro modified Nikon D5300 to put on it. The D5300 has the Sony sensor in it. It’s actually the same sensor ZWO is using in there 071 series.
I was using the GT71 on my Ioptron Sky Guider Pro but I picked up a Williams Optics Zenith Star 61 for that rig.
When I’m not using the GT 71 for imaging I can use it as a guide scope.
