Posted with Viktor's permission. We are honored to post photos of this very well built custom telescope by Viktor Zsohar. It is a tribute to Viktor's craftsmanship and certainly does iStar proud:
This telescope is a great performer in its class, and is a joy to use! It is awesome for observing deep-sky and fantastic for the Moon! CA? Yes, the CA is undeniably present on bright objects, but I think it is up to a person how much it is tolerated or not? For example, I could not take off my eyes off the Moon for an hour or so, even when CA was present, because I was immersed so much in observing the craters and other fine surface details! Is this telescope good? Yes, darn good 
Actually, this refractor may be the perfect outreach kind of scope!
I am very happy with it!
The focuser is an AP 2.7" with greased rack and pinion and I added an AP extension between the focuser and the tube so that it can be exchanged later on for a 4" AP focuser if needed. The length of the system is exactly as planned. I have 7" from the end of focuser to the focal point and it comes into focus with a diagonal even for me who wears strong glasses. The 7" back focus also makes the telescope bino friendly, however, this will need to be verified. The tube mounting is a 15" AP ribbed plate with Parallax rings. The tube is not heavy considering its size. My AP 900 is good enough to hold the refractor, but I have to balance it carefully.
