TMB APM 8”F6 achromat OTA CHROMACORR Feathertouch ex. Condition is Used. Shipped with FedEx Ground or FedEx Home Delivery.

Razor sharp. Near new, in storage for years, retractable dewshield, 2” Feathertouch focuser on 5” extendable drawtube, make this incredibly compact. 42”L, 40lbs. Handles like a C14 OTA, worked great briefly on my Atlas/EQ6

Yes I am including the Chromacorr (approaching $1000) and 2” diagonal. N-type.

Rings, Vixen rail, has that European instead of Vixen finder adapter bolted to the tube but not the finder bracket shown in pic1. You will need a bracket and finder.

When tilted and spacing adjusted correctly provides ED doublet color correction. When spaced for a longer F# vingetting occurs, as the Chromacorr is designed for F7-F8, but then the correction gets better and better. The Chromacorr color corrector is sensitive to adjustment, like collimation. I added longer radial screws of the 3” drawtube where engages the Feathertouch so centering color is more easily performed, rather than Yuri’s concept that you loosen the whole backplane to fine adjust.

only issue is some paint missing from metal cap, way it was received from APM

I expect shipping on CONUS $175. I will bulletproof package, 3” foam rubber, which will be shipped by Fedex. Of course you can pick up in SoCal, I can hold for someone coming a distance. I am not set up for a big mount currently.

Check my AstroMart article in the 7/17/2006 file TAMING THE WILD ACHROMAT for history.
