  • Fits 115mm ID mounting rings (optional)



First, I’d like to thank to the people who have been patiently waiting for this announcement. This is my first BORG telescope I was deeply involved myself, as a decision maker, mainly in mechanical sections from the early stage of development time. So you might feel something different from the classic BORG style.

I’m sure this should be a very unique 4″-plus airline transportable telescope, which is the perfect for the overseas expedition. Personally I’m wishing to take this astrograph and Fuji GFX 50R camera to the southern hemisphere some day. That is my current dream. As shown above, a carrying bag is wide enough for a motor unit or guide scope setup.

The price of F3.9 conversion kit for existing 107FL users will be announced shortly. Also I will write up the recommended mounting rings. I’m sure this ring size is widely available at most of astro shops, including Hutech. So far, no BORG-made rings are scheduled yet.

BORG and I have made the dream machine for you at present our maximum efforts and “at the affordable price” (I hope you agree….). I really wish you will enjoy fluorite-created high color contrast and transparent images at F3.9 speed anywhere on our globe.
