Hi Greg,

No baffles yet. The dew shield and main tube just have flat black for now. I will make them soon. I had thought that the ota was lighter than the Celestron C6-R but it's about 5lbs heavier. The tubing is not your standard "sonotubing." The tubes are heavy duty mailing tubes from Yazoo Mills. The tubing wall thickness is about 1/4". These tubes are quite precise and very straight. I have made a couple of 8" F/12 refractors using this tubing.

New scope in the works

Posted By Keith Lawson

The optics are on the way. Hope to put together something interesting (Coulter 10" F/16 Cass) in time for the moon and the planets.

We have old Coulter GLASS! Fingers crossed. Hope this works out as planned.
