This is the latest acquisition to my telescope bin. A Williams Optics Gran Turismo 102 with .8 field reducer and flattener. This is the rig that took all the images you will see in this tab. I also used an Optolong L-Enhanced filter.
The scope was imported directly from Williams Optics in Taiwan and came neatly protected in the soft case seen in this photo.
Every part had it's own tight fitting compartment.
The guide scope is a 50 mm helical guider with a Roto Lock at the rear. Although it is a nice guider it must use a ZWO ASI120MM mini guide scope and since I didn't have one of those I opted to replace it with my trusty StellarVue 60mm APO refractor instead using the WO rings to install it.
The adjustable .8x field flattener/field reducer came was installeed and set before mounting outside.
There is a built in Bahtinov mask for focusing in the front scope cover. You just unscrew the front cover to use and then replace the front cover and slide the cap off for imaging.
It comes complete with cradle and built in top bar for the guider.
Pictured below is the remote imaging setup by ZWO called ASIair. This little box allows almost complete control of your imaging rig from inside hte house. I can pick targets, control the mount, control the imaging camera and guide camera, focus and even shutdown. I must go out to turn the mount on and if need be focus the guide scope, but that is it.

ReplyDeleteGreat overview of the Williams Optics GT 102 refractor and the imaging setup. It’s impressive how this telescope, combined with accessories like the 0.8× field reducer and flattener, can produce such beautiful wide-field images of objects like the Horsehead Nebula and the North America Nebula. Pairing a high-quality refractor like this with ZWO imaging gear and ASIAIR control really makes remote astrophotography much easier and efficient. Thanks for sharing your equipment details and results—very inspiring for fellow deep-sky imagers!
