Quote:Ok, this was an abject reminder of why I don't don't use these little toy telescopes for planets.
And the binoviewer for the first time may have worked against me.
Not that the view was worse than mono-vision, but I don't think it was better.
These little scopes just don't have enough brightness in mono-vision to allow very much high power observing, but the binoviewer for me dimmed the image enought at this aperture to work against me.
Now there was a fair amount of detail visible. I tuned in just as GRS had rounded the limb, and I could see the vorticies that trail it, and I could resolve three of the Gallileen moons as disk but Io was more point like. But I can do that in Mono vision too.
But the problem was the image was just to dim at 150x.
To be fair, I usually get my best planetary result at 1mm exit pupil, and at this power, the image was just acceptably bright, but I think I have seen it at least as well using mono-vision. and I think that the added brightness in mono-mode made up for only having one eye to observe with.
This is the first experinece with the binoviewer that has been less than great, but it was not at all bad.
It just wan't better either.
But again, I just am not a fan of little telescope for planetary observing. Just wanted to give it a try for the fun of it.
