I am offering for sale a very rare and difficult to find Borg 101ED f/4.1 scope including Borg's #7704 Super Reducer.
I have been imaging with this setup for a little over a decade and it has been a real treat to assist me in learning the hobby and receive recognition from the images it produces. This telescope is the one that was used to capture the image in Software Bisque's current advertising. I will share a copy upon request. I have traveled the world with this scope. With the Borg modular design, it breaks down small enough to fit into a carry on suitcase. I have imaged with it in Japan, Australia, Arizona, New Mexico and at my various home observatories. It is permanently mounted in my observatory when it isn't traveling with me.  

This system is nearly turnkey - all that is needed is a guide camera. I had a custom adapter made which allows for the precise back spacing required for the Super Reducer when using the QSI WSG. I am the 2nd owner of this scope and have owned it since 2009. I am the original owner of the QSI 683 WSG/WS-8 camera, purchased around 2013 which has been a solid performer and only has a single "bad" column. The bad column and the hot pixels present in the raw frames are easily calibrated out. I will share dark & bias frames upon request. I have always ran the camera at -15C, but it will go much deeper. The camera comes with both the WS and WSG adapters providing the ultimate flexibility for your specific system. The camera is loaded with the top of the line AstroDon 31mm filters. LRGB and SHO 3nm. 

The objective was recently serviced by Borg in Japan for cleaning and factory re-collimation. I have a lot of documentation available to the new owner for the different configuration options and part numbers. Ted at Hutech is also a great resource. 

I am also offering the upgraded FeatherTouch focuser along with the MicroTouch wireless motor control from Starizona. This provides for crisp focus which is an absolute requirement when imaging at f/4.1.

The QSI camera and Microtouch come with their original power sources and RJ12 cable. You will need to supply the appropriate USB cables for each. The dew shield on the scope slips down when pointing vertical, thus you will notice an elastic band holding it in place. It has been this way since I bought it. There are also a few minor paint chips on the tube and dewshield.
