10th April Jupiter and Ganymede

[Lester]

Hi all,

The seeing wasn't as good as yesterday, but still okay. There was high humidity this morning, where as yesterday humidity was very low.

Captured with DFK21af04 and 2x barlow. Processed in Registax 5, Astra Image and Photoshop CS4.

Great image Lester. I have tried planetary and it is not without many challenges. Hard work from focus to processing isn't it?

Ganymede looks fantastic. Good colours on-planet.

Baz.

Thanks Baz for your comments.

Another nice image Lester,

The seeing does make a substantial difference, doesn't it.
Lester, just a thought, in Astra Image try doing an alignment just on Ganymede. With such a nice image scale I think you may find some detail on Ganymede. I mean some colour contrast, darker and lighter areas.

Do one alignment on Ganymede and another version of the same image but concentrating on the alignment of your RGB channels with Jupiter.

This should give you the best possible Jupiter and Ganymede on different versions of the same image. Then cut and past the good version of Ganymede onto the best version of Jupiter.

Just a thought
Cheers

Hi Lester

Another good effort although the poorer seeing has robbed you of the crispness and finer detail recorded in your previous session. However, it is nice to see the pairing with Ganymede once more, sort of puts the scale of things into perspective!

Cheers

Nicely done again Lester, make the most of the good seeing!

Just a question about the moon - Ganymede is pretty much grey in colour, are you sure this isn't Io which is yellow?

cheers, Bird

[Lester]

Thanks for your comments everyone.

Trevor thanks for the tip of aligning on Ganymede, I will try it.

Anthony, I am just going by the Jupiter2 program that had Ganymede closest and Io second out from Jupiter. Unless there is a error with the Jupiter2 program.

Nice image Lester, you captured the NEB outbreak too.

Well done!

[Lester]

Thanks Mike; the NEB outbreak, I will remember that and watch it with interest.

Trevor I tried the alignment on Ganymede in Astra Image but didn't get any improvement. I enlarged the image 200% but couldn't get it any better as the 1 pixel movement was too much.

If I get good conditions again and use the extention tube, that will help to get a bigger disc, and perhaps some detail.
