Great site
I have had comparable views of Jupiter and Mars with my 6mm ep and 2x barlow on rare occasions when the seeing has been excellent and plants near, or on meridian.
It's pretty rare that seeing is good enough for me to use 240x mag with my current setup tho'. I find my 6mm ep with my f5.3 reflector (133x) give pretty good results with the planets, the images are small but very clear.
One day I might be able to afford a high quality short fl ep
