Re: A Blue Jupiter

The image seems to have a higher than normal resolution. Some have mentioned that it is incredible considering the filter used. I believe it is because of the filter used. People should realize that at 400nm violet, the resolution of any telescope will be 39% greater than at 555nm green. That would make your 9.25" aperture equivalent to a 13" instrument. Add to that the largish central obstruction of the C9.25, which increases the resolution slightly more at the highest frequencies, and your scope might be working at almost 14" effective aperture.

Hmm...makes me think I should try my Magenta filter on Jupiter tonight...

Hi Roland -

I think it is superb seeing that let this resolution be realized.

In RGB Jupiter images from my location, the image is far more affected by seeing conditions in the blue than in the red with the green somewhere in between. I have not yet had an experience where the blue image did not serve to reduce the resolution of the final Jupiter image when I try to incorporate it into the luminance information.

This may be one reason why we are not seeing a big migration from Barbados to Buffalo?
