I'm preparing to make my first mirror and I've started gathering the supplies I need. The only problem is with the polishing pitch. Since Gugolz optical pitch is mentioned everywhere, it seems to be the go-to material. Unfortunately, there is no way of obtaining Gugolz locally where I live, and there is no way to ship it here. I was wondering if there were any alternatives or a recipie to make a MacGyveresque optical pitch.
I've also read online (from wikibooks: https://en.m.wikiboo...lescope_Making#) that pine resin can be used to make optical pitch. (I understad that if pine resin was a suitable material there would more references to it online, maybe can someone explain why it wont work and what properties should I look for in a suitable material).
Thank you and clear skies,
