Since I had dismantled it and removed the fungus (in between the two elements) I decided to go through and mod the heck out of it.
I sanded off all the paint (which was badly scratched from my tube rings anyway) and repainted the dew shield with Hammerite cream paint. The finish was not so good.
The main tube is unpainted. After I sand the dew shield again I will have both powder-coated, there's a shop in Defu Lane which is popular with case modders. Haven't decided on color..
I also shortened the main tube by 4" so that it is BV-friendly. In retrospect even a 2" shortening would have sufficed.
Finally I snuck upon a fancy William-Optics focuser on A-Mart. These are nicer than the GSO ones (more expensive too but I got it for much less than full price).
