Just unwrapped and cleaned up a Jason 454 60/910 optical tube. This one is a Circle Z ,and the finder is quite different ,although still the reflex type,than my Circle T complete Jason 454.With this Z an image is still seen in the main eyepiece even when the finder is in use.After removing interior cobwebs and lens dirt it looks pretty sharp.No objective lens flaws seen.Will have to superglue a small nut over the drawtube hole for a new drawtube holding screw as there is nothing present.Focuser smooth but right side knob missing.Dew cap dented on rim. But for $14.25 I have rescued a hopefully good performing scope tube from the landfill or worse fate!Tonight we shall see if the Z is as good optically as the T.
