Finally, the ED astroscopes can compete with photographic leses. (4 Viewers)

Hi everybody, I have been using ed astroscopes for 10 years. I love their image quality and low weight, but I was annoyed by how difficult was using them handheld and focussing efficiently. Now I have found the solution. In fact two different solutions. There are a couple of 360mm ed doublets from TS Optics and Tecnosky that use drawtubes to focus, and with a bit of practice and the correct camera you can nail focus with great speed, enabling you to make photos ot rapid moving birds anf birds in flight. It’s very important that the viewfinder of the camera have high resolution. I use Panasonic Lumix G9 an find it sufficiently detailed to nail focus. In the past I’ve used a Sony a7r2 but the viewfinder’s resolution wasn’t enough to focus correctly. Beside that, I can use te combo as a very useful telescope thanks again to the very large and detailed viewfinder of the Lumix and the fantastic image stabilisation. The total weight is 1600gr. I think very low for a 720mm f5.9 objective.

The other solution works with every scope with a 1.25” holder. You can attach an adapter and use it as a draw tube. This way you can focus very fast and accurately as soon as your camera has a high definition electronic viewfinder of at least 3.6 million dots.
