Thanks for the encouraging comments. Taking long exposure pics with the lx90 unguided is a challenge. The wooden wedge works well but needs some modification to its adjustments but is stable and damps down vibrations. The focal reducer is just an achromatic lens positioned in the visual back. i have given info on this forum over the last 18 months on homemade focal reducers. will post more pics as they come , moons going to be in the way when weather clears.
regards philip
