Title: Jupiter 16 March 2014 (Double Shadow Transit)
Post by: The Thing on Mar 17, 2014, 21:44:36
LX90 8", 2x ED Barlow, QHY5L_II Mono 107fps 600 of 1200 frames processed in Registax taken in Beckenham. The sky was not the best.

I know what you mean - I gave up just as the shadows reached the mid-line.  The seeing deteriorated quite rapidly.  I like your Io!

Io doesn't show up as well on earlier captures. I think I caught it at the right moment as the limb of Jupiter is quite a lot dimmer than the central area so the moon shows up well, also it just happened to be over a dark band :) Something to bear in mind next time I'm trying to capture a transit.

Ok having seen the recent posts from Mark and Duncan on the rare imaging oportunities available at the moment, what are the optimum parameters for exp nos for Jupiter regarding rotation?

Don't stack more than about 3 minutes of data to avoid rotation issues.

That's really excellent considering the conditions that night.
