still for sale

can throw in for free, a 4 1/2 inch newtonian OTA which may have usable parts for your scope build. It needs mirrors resilvered, found that thrown out. It has a focusser for a smaller size eyepiece, and a seconary mirror and spider. Dont know if you can use these for your planned 6 inch using my blanks.
