Thanks for that John.
I've measured the inside of the focuser which is threaded. I also found a 52mm thread and it did wind on. I then found a 52/48 step down ring on eBay for $1.80 delivered. I'll see how this ring goes before taking it further.
My first idea of a 2"/1.25" adapter still does interest me as it would again reduce the need for multiple filters. I wonder if anyone knows of someone who could machine one? Please let me know & I'll contact them.
