Bought a $40 'moon filter' that made everything look like a blue blob

Saw an ad for this special filter that promised to cut glare and show lunar details, but when I screwed it onto my old 70mm scope, the whole moon just turned into a fuzzy, bright blue circle with zero contrast. I basically paid forty bucks to make my view worse than it was with my own eyes, you know? Has anyone actually found a decent filter that works without costing a fortune?

It's the same with a lot of cheap gear, promises way more than it delivers. You end up paying for a fancy name on a piece of plastic. It makes you appreciate the simple stuff that actually works.

Wait, "fancy name on a piece of plastic" is so real. I bought something like that once and it broke in a week. You really do learn the hard way.

That forty bucks could have bought you two cheap eyepieces that actually work. It's like how people pay extra for "premium gas" in a car that doesn't need it, or spend twenty dollars on a fancy bottle of water at a concert. We all get tricked by the idea that paying more means better results, when really it's just marketing hitting us at the right moment. The moon filter industry is basically just selling us colored glass and hoping we don't notice. You learn pretty quick that the real secret is just using your scope on a clear night with steady air, no filter needed.
