18th April Jupiter

[Lester]

Hi all,

There was no jetstream, but a breeze from the east and plenty of humidity, plus transpearancey was down slightly.

Jupiter looked steady, just that the detail wasn't visible when looking beyond the EQ belts. The seeing peaked briefly (5 minutes) to 5/10 and then dropped to 2/10.

Hope to get better in the next few days.

Still some good detail visible there, Lester. Is that Io? Good colour!

The background is quite "grey", in my opinion you could probably raise the blackpoint but it doesn't really detract from the image.

More fine work from you Lester. A very impressive amount of detail at that image scale. Nice to see one of the Galilean moons too.

Cheers

Dennis

Thanks Mike and Dennis for your comments, appreciated.

Yes that is Io.

[Matty P]

Another nice image Lester. Nice colour and HUGE image scale.

Great to see Io in the image aswell.

[Lester]

Thanks Matty, I had to downsize the image to keep it looking smooth during processing.

I was pleased how sharp Io came out, as it moves so fast in its orbit.

Here is an improved image from another avi. Although I captured for the same amount of time for all avis, Io is streaked in this one and sharp in the first image. I tried doing a RGB align but that didn't fix the problem. It has got me a bit puzzled.

Anyway, Jupiter looks better.

I planned on testing out my new camera on jupiter tonight... The weather, ahh... Rained on my parade so to speak...

Very nice shots, might I ask what equipment was used?

[Dietmar]

...whow! the second one is really cool!

Nice detail Lester - looks like Io is a bit stretched in the second image - perhaps it hasn't registered properly?

[Garyh]

Plenty of detail there in the second one...nice :thumbsup:

Thanks Alex, Dietz, Peter and Gary for your comments.

I use a DFK modified camera with 2x barlow and small extention tube, with 14" LX200 that has been flocked and cooled to ambient.

I was out imaging Jupiter this morning and now I think I know why Io is streaked in the last image. I had FPS set on 30 and yet it was only recording at 15fps. It wasn't until I moved the shutter slider from left to right that the camera began recording at 30fps. So this last image may have been recorded at 15fps, and as I limit my runs to 4050 frames; the avi could have been just over 4 minutes instead of just over 2 minutes.

Little bit wiser now.

Wow fantastic clarity in the second processing. Not sure what you did but it worked a treat.

[Lester]

Thanks Matt,

Different avi and the seeing must have been slightly better. I have stacked the same avi in Registax and depending on what marking it is stacking on the image can come out sharp or very mottled.
