Imaging Jupiter and the Full moon

Postby cwardlaw » Wed Apr 12, 2017 8:03 pm

I have been imaging Jupiter and the full moon a couple of nights ago. I simply used my DSLR mounted on a tripod imaging at different exposures to allow for the varying brightness of the Moon and the planet. I have images which I now want to compine in some way but have not worked out what to do. I have a few processing tools but not photoshop. Can you help please.
Many thanks

It isn't the easiest thing to do convincingly but if you cut out the moon from the image, and then past it on the exact position the moon would be on the Jupiter shot, that would be a start. Hopefully a dim moon will be present on the jupiter shot to guide you. You might have to soften the pixels on the edge of the moon once you've pasted it, to blend it in.
I use an 11" Celestron SCT (CPC 1100) on an equatorial wedge, housed in a 2.2m Pulsar observatory. I use a ZWO ASI1600MC and Canon 500D for imaging.

Sorry if this sounds boastful but I've done it. I took 3 shots at 300mm focal length:

1. Moon at 1/4000 second ISO 400
2. Moon and Jupiter at 1 second exposure ISO 400 (1/2 second might be enough)
3. Jupiter with moons 3 seconds ISO 6400

I then used #2 as the base and copied and pasted #1 and #3 on top of the Moon and Jupiter.

You could try imaging Jupiter with a telescope and webcam and pasting on top of #3. I've done a few like that when the Moon hasn't been close.

Why use Photoshop when you can download GIMP for free! Just go to my website and select "Software Downloads" from the drop-down menu.
How can I be one with the universe when we don't know what 96% of it is.
