Very nicely engineered Rolf.. and the proof is in the pudding, yes definitely better results although your present image tracked better than your previous.
Always wondered about the string mounted secondary when I was researching better designed secondary holders and spiders.. I think it was stellafane which brought my attention to the idea for visual scopes a long while back. I wondered how they would hold up for imaging.
Have you tested it to see how stable it is for movement on long exposures and when advancing to the meridian.. wind/ wind gusts??
How has it performed??
Thanks for sharing
