I have a cheap telescope from CVS. Don’t know if I’ll be able to make out much detail. Says it’s a 50x/100x.
I would think for most people, the problem is not the telescope, but the ambient light (streetlights, house lights, etc.) that blot out the stars and planets.
I picked up an old Meade from a thrift and checked out Jupiter. Unfortunately, it is so bright there is no detail to be seen, just a blinding disc.
