Have for sale my Combo Quark , I used it with a Takahashi FS76DS scope and either a 2X Focal extender or a 4X Powermate
For use on SCTs, Maks, or refractors of F/15 to F/30. The user needn't worry about configurations. Just insert Quark in your diagonal, add an eyepiece and view.
Also included is a Energy Rejection Filter suited to I believe a 8" SCT I never used it as it came when I purchased it here on IIS .
I added a Baader Clicklock Eyepiece accessory with a built in M42 threads to directly attach a camera, I used the Apollo-M Player One camera. Original fitting also included
$1500
Pickup 2213 or post
Images I personally took with the setup described.
