Used SCT focusing questionPosted By Jim Nelson |
The short focus nagler is probably too much power for the scope - at over 400x, it's certainly pushing it. And your local seeing conditions probably won't allow that high of a magnification except on the best of nights, with any scope. On many nights, I'm limited to about 200x as my maximum useful magnification by the atmosphere.
