ASTRO: Question for you guys, help..
Ok Joel - I can see it - I downloaded you gif file and messed around
with it in Corel Photopaint. If I increase the brightness I see the ring you are referring too. What I was seeing in my earlier post is not related this ring. There are a ton of artifacts in my images when I really "mess" with them but I go for my best balance on my equipment. I tend to work on images in a dark room at night and this affects the what I post and keep. However, I've never seen a ring around Jupiter in my images like this one. I'm not saying that I don't have them, I am saying I've never seen them. Something for me to do this weekend!! I'm attaching a repost of your gif file with the brightness turned hideously up. I hope you forgive me. - take care and let us hope Gustav will just fall apart - Rod rod wrote: Hi - On a couple of frames on the animation I can see something on the left side of Jupiter that might get interpreted as a blue arc but not a halo.

Yes I can easily see it on my ViewSonic 19 inch wide flat screen LCD.
It seems to intensify with the more exposed frames.

Thank you all. I believe I have corrected it with the attached gif. Now
I'm trying to determine how much differently everyone else is seeing what I see. Besides the blue halo, did the images look OK? I can see a bit of overexposed brightness near the center, but I would consider these pretty good results. Does the color, contrast, brightness etc look OK? Please don't worry about hurting my feelings! I'm going to get some monitor calibration software soon. |

Hi J. - Your animations are infinitely better than any of mine ;).
Since you've asked for scrutiny .... besides Jupiter itself I began to focus on the moon which in your animation on my screen slowly fades and slightly reddens. Maybe that is natural but this is something I noticed. Perhaps when available you might want to balance the color and intensity of an available moon. But as I said before, I tend to work in a dark room and so my monitors are rarely set to daytime standards. I did not see that halo until I really ramped up the brightness and intensity. BTW - you've inspired me to move my best monitors, the old Samsung 19 and an older Sony 21 Trinitron onto my main table this weekend. I'll probably crush the table under the weight!! Please let me (and the newsgroup) know about what you learn about your monitor calibration. I am very interested in the subject. BTW - power is still on, the center major Hurricane Gustav is a mere 150 miles from my position right now. I'm in between rain bands right now. - Rod J. Warren wrote: Thank you all.

Thanks Rod! I might be wrong, but I think in regards to the moon changing
in each frame, it has to do with the brightness of Jupiter effecting the moon as it moves away from Jupiter. The closer it is to Jupiter, the more it brightens up the moon, the further it moves away, the dimmer it gets. Each frame was processed the same and captured with the same settings on the camera, so that is the only thing I can think that would change it. Darned if I know though. Good thing Gustav is going to miss you! Not so good for LA though. "rod" wrote in message m... Hi J. - Your animations are infinitely better than any of mine ;).

Hi J. - yes I thought of that too (the distance to the moon and it's
brightness and color) - I just doubt that the brightness would change THAT much (after all we are talking about distance from the Earth to Jupiter) the but that is an "armchair" opinion that I would happily abandon. That would be great if our cameras were that sensitive. There is probably enough high quality amateur images of Jupiter to test this idea (that our cameras detect changes in brightness in the moons in their orbits). One thing is certain - your images are consistent with a moon receding from earth. If the change change in color and brightness is real, I would say you have made a truly interesting discovery. - take care - yes Gustav is a potential mess. I have hope that it will track to to the west of New Orleans and that it will weaken. We are overcast right now but I could see a few stars a hour ago. - Rod J. Warren wrote: Thanks Rod!
