What Filter Do/Would You Use With A 150mm F8 Achomatic On Jupiter?
Hello There
A few days ago I observed Jupiter comparing a yellow #8 filter against a four inch aperture mask. At the time it looked like the mask did a better job with color. This evening I noticed the filter showed more resolution and there was no great change in color. The atmosphere was much better than the last time out allowing 200 mag. Perhaps the sky conditions made the difference. There was observed swirls around the Great Red Spot only visible with the filter. I also compared contrast and resolution with and with out the barlow at 120 mag. I will not be using barlows any more. I am happy with the #8 yellow on Jupiter but curious what others use. Thanks to you all.
