I have an old meade Rg 8" f/7 fiberglass tube. it comes with the aluminum end rings and vinyl caps. It has a 9.7" O.D. Has some crazing or small cracks. It has various holes from the components that were mounted on it. The current focuser hole accepts the astrosystems 2" low profile crayford. This tube would probably be best suited to use as an f/5 or f/6 dob. I also have a pair of the discovery adjustable side bearings for the tube. I would like $75 for the side bearings, caps and end rings - the tube is free. I do not think the tube is worth shipping so I would like a local pickup fo it. I will ship the balance of the items for the asking price however. If I am asking too much polease feel free to make me an offer. I would also consider a trade for a f/6.3 SCT focal reducer.
