Quote:Is the resolving power that of a 120mm scope?
Quote:Thanks, David. I was just interested in your impressions and don't want to stray from the topic of observing Jupiter. But, the concept interests me.
Quote:Nice sketch, amateurs are often able to catch new stuff on Jupiter as Jup comes out from behind the sun to start another observation season , I think GRSJr. was discovered this way.Great sketch again.

Quote:I can promise you I would not countenance such a loss of res! Close doubles (below 0.5") are well within reach with this setup - it's aperture spacing (as indicated to Ivano earlier) that determines/maintains resolution. I am out observing in a couple of hours and will push it - seeing allowing - to get further evaluation.
