Imaging Jupiter and it's moons

[stevepenny]

Hi,

I'm having an odd problem when imaging Jupiter. I'm using a Canon 1200d piggy-backed onto an EQ2 mount with 75-300mm lens.

I have tried various setting but I'm finding it difficult to capture the moons without Jupiter blurring due to its brightness.

Short exposure Images where Jupiter is clearly defined tend to miss the moons and longer durations bring the moons into play but Jupiter loses clarity.

The mount is driven (small battery operated motor) so I'm limited to about 45 seconds per exposure at 300mm at which point it starts to trail.

Any guidance would be appreciated.

Normal.

To get both people take images of Jupiter, with Jupiter right.

Then images with the moons right, and Jupiter over exposed.

Then somehow remove the over exposed Jupiter and replace it with the correct Jupiter.

Don't ask how as I have no idea at all.

Same happens with M31, and I assume M42.
