My first astro instrument at age 24, was a pair of 7X50 Tasco binoculars mounted on a homemade tripod. Six month later (on the advice of a friend) I put $125 (1965) into purchasing a 60mm Unitron refractor with altazmuth mount and slow motion controls. That was good advice; my little Unitron has been a most useful instrument ever since. In the early 90's I added a 5 inch Celestron(Smt-Cas) and a 254mm (10 inch) Dob which all the kids call Big Red or Mr Wms. Big Red Cannon (I'm a retired teacher). My current binoculars are 10X50 Adlerblicks. Many satisfying hours spent with all four instruments, looking at the sky alone and sharing sky views with others.
Cheers,
