hello folks. the rebuild is going along quite well! took an old orion deep space explorer Dob apart to clean and fix what ever, found the old focuser to be of little to no value so bought the GSO crayford 1.25. from Agena and decided to rebuild the whole thing! (lot of help from different people, including "Newts for the net") bought some old criterion 6" parts from a very good fella, and when they got here the shipping company had dropped it and broke the mirror cell. (bummer) any way, got my sonotube at lowes and went to work. used a bar of 1/4x1.25" aluminum, cut the old cell apart and made a cell for the new scope. everything went together fine. dropped a ton off the scope. from 13lbs down to 8.4lbs. not quite ready for viewing but here's the project so far. thanks for all the help!

A little midnight blue paint on the outside of the tube and nobody will know that OTA didn't cost $300.

Nice job,
JT

thank you Jay! i was just thinking a nice cobalt blue would be a good color for this one! think i'm going to put a ring around the top end to stiffen it up a little as well. rings are the next project. should be fun on the SVP mount. might be a bit long but it's pretty light. we shal see! lol.
