Dear all
Managed to get some reasonble views of Jupiter with good magnifcation using my saxon 740mm with a barlow magnifier. I struggled for some time now to get anything other than a massive blur usi ng the barlow but a bit of patience paid off.
The resolution was still slightly blurry compared with low magnification but I could still make out the major cloud bands.
Calibrating the finder lense during daytime using some chimney stacks about a km away improved my ability to quickly find and maintain the desired target
