This is a private sale!
Before I come to the actual offer, let me explain first why I have to sell this telescope even it hurts me a lot that I have to sell it.
I own this telescope now for 4 years and it was simply perfect for taking pictures with my Canon 600D, especially after I made some tuning. (some pictures you can see attached)
Last year I had an accident which caused a dislocated shoulder and splittered several bones. Now I have a plate in my shoulder which makes it impossible for me to lift the telescope or even try to balance, it is just too heavy for me and is very painful.
