I'm not sure what was more annoying, the winds gusting to 25 mph or my wife letting my dogs out just when it looks like I will have a sequence w/o wind gusts. Needless to say, my dogs have to come visit me and my scope when we are set up. This is the first of about 6 sequences shot. Not sure how the others will turn out, but I'm very happy with this one. Europa is really shining bright and its shadow is crisp and clear. 1100 frames stacked. VERY little processing. Just one wavelet with no additional sharpening or noise removal in PSP. Comments appreciated. If any of the others top this one, I'll post them, otherwise, this is it. -------------------- Mars Watch All images taken with: Celestron NexStar 8i SCT DBK 21AF04.AS K3ccd/Registax4/PSP8 ALPO Member #4287 Post Extras:       Mike Phillips professor emeritus Reged: 02/21/06 Posts: 710 Loc: Swift Creek, NC - 35.682 N, 78...

Nothing else touched in regards to color/saturation. Perhaps I'm biased, but I think the DBK's result colors are just as good as the monochrome cameras. -------------------- Mars Watch All images taken with: Celestron NexStar 8i SCT DBK 21AF04.AS K3ccd/Registax4/PSP8 ALPO Member #4287 Post Extras:       Lunatiki Pooh-Bah Reged: 08/07/05 Posts: 1252 Loc: Amarillo, TX Re: Jupiter 08-26-08 Europa transit, excellent see [Re: Lunatiki]       #2603926 - 08/26/08 12:37 AM Attachment (15 downloads) Edit   Reply   Quote Quick Reply   This was the best of the group. I find it interesting that Europa's shadow doesn't appear exactly circular as it does in the image above, when it is closer to the CM. It is more of an oval in this one. I'm assuming that is natural due to the curvature of the planet towards the edge? First time I have ever picked something up like that. I'd appreciate any input on that. -------------------- Mars Watch All images taken with: Celestron NexStar 8i SCT DBK 21AF04.AS K3ccd/Registax4/PSP8 ALPO Member #4287 Post Extras:       Lunatiki Pooh-Bah Reged: 08/07/05 Posts: 1252 Loc: Amarillo, TX Re: Jupiter 08-26-08 Europa transit, excellent see [Re: Lunatiki]       #2603942 - 08/26/08 12:55 AM Attachment (9 downloads) Edit   Reply   Quote Quick Reply   Well, just when I think the last one was the best.... the last one I process, which happens to be the first sequence I shot... -------------------- Mars Watch All images taken with: Celestron NexStar 8i SCT DBK 21AF04.AS K3ccd/Registax4/PSP8 ALPO Member #4287 Post Extras:       solshaker Pooh-Bah Reged: 06/06/06 Posts: 1305 Re: Jupiter 08-26-08 Europa transit, excellent see [Re: Lunatiki]       #2603956 - 08/26/08 01:07 AM Edit   Reply   Quote Quick Reply   you are cranking out some great stuff, Joel! id say youre spot on with your reasoning about the shadow. heres a short animation showing the elongation on the rim. on nights of steady seeing ive been able to see this visually, also. link -------------------- My Gallery Post Extras:       isramirez scholastic sledgehammer Reged: 11/04/05 Posts: 762 Loc: Mexico City Re: Jupiter 08-26-08 Europa transit, excellent see [Re: solshaker]       #2604575 - 08/26/08 11:23 AM Edit   Reply   Quote Quick Reply   Those are really great shots Joel -------------------- Santel MK91 & MK6 IntesMicro 715 Celestron SCT6 & ONIX80 EDF Meade SN6 & AR6 Chinese 6in MakCass.Gregory DBK + DMK + NexImage + LPI CG-5 & LXD75 Mounts many EP's, Barlows and Binoviewers Great astronomic passion Post Extras:       Lunatiki Pooh-Bah Reged: 08/07/05 Posts: 1252 Loc: Amarillo, TX Re: Jupiter 08-26-08 Europa transit, excellent see [Re: isramirez]       #2604862 - 08/26/08 01:35 PM Edit   Reply   Quote Quick Reply   Thanks guys. I've been lucky with seeing (jet stream parked north). It does really make me wonder if I'm getting these results at less than 30 degrees, what would my results be if it were say at least 60 degrees overhead. I wonder how much of an improvement it would make. -------------------- Mars Watch All images taken with: Celestron NexStar 8i SCT DBK 21AF04.AS K3ccd/Registax4/PSP8 ALPO Member #4287 Post Extras:       isramirez scholastic sledgehammer Reged: 11/04/05 Posts: 762 Loc: Mexico City Re: Jupiter 08-26-08 Europa transit, excellent see [Re: Lunatiki]       #2604945 - 08/26/08 02:11 PM Edit   Reply   Quote Quick Reply   60 degrees? ... i can only have dreams with that but you know in years coming we are going to have that opportunity Post Extras:       James W. super member Reged: 05/14/07 Posts: 169 Loc: Maryland Re: Jupiter 08-26-08 Europa transit, excellent see [Re: isramirez]       #2604976 - 08/26/08 02:18 PM Edit   Reply   Quote Quick Reply   Great images Joel.

I did this animation a bit differently, mainly for the challenge and the practice. I think it is a great improvement from the one above. Mainly in regards to sharpness and noise. web page -------------------- Mars Watch All images taken with: Celestron NexStar 8i SCT DBK 21AF04.AS K3ccd/Registax4/PSP8 ALPO Member #4287 Post Extras:       James W. super member Reged: 05/14/07 Posts: 169 Loc: Maryland Re: Jupiter 08-26-08 Europa transit, excellent see [Re: Lunatiki]       #2605856 - 08/26/08 09:00 PM Edit   Reply   Quote Quick Reply   Nice job Joel! -------------------- James Meade 12" LX200 GPS Celestron C6-S Stellarvue Nighthawk II Coronado PST H-Alpha Canon Rebel XTI Nikon Coolpix 4500 Meade 8" LX-5 RIP 10/05 Post Extras:       siriusc super member Reged: 04/03/07 Posts: 184 Loc: Racine, WI Re: Jupiter 08-26-08 Europa transit *animation added* [Re: Lunatiki]       #2605937 - 08/26/08 09:42 PM Edit   Reply   Quote Quick Reply   Really great, Joel! I can tell you've been doing this for years, and enjoying every minute! I've been observing planets for 34 years and imaging for just one. It constantly amazes me how you and several of the other guys here can stack thousands of blurry images and come up with a sharp composite that has real scientific value. Keep up the good work. Regards, Dan PS: I was just thinking the same thing, that you should do a correct orientation animation... I like it!

You're also getting some wonderful color, detail, contrast and softness! I'm wondering about the faint halo around the disk. It shows brighter in the animation, but is still in the man stills too. Not a dig or complaint, just wondering! I love the photos!

Are you talking about the inner edges of the disc, not that outside? I think I see what you are talking about on the animation, a bit in the stills. If that is what you are talking about about, I think it is shadowing. I think the animation makes it look a bit weird. If you look at frame 3 in the animation, you'll see some green pixel-type flashes on the lower right of Jupiter that aren't there in the still, so some how the animation program is doing something to them. -------------------- Mars Watch All images taken with: Celestron NexStar 8i SCT DBK 21AF04.AS K3ccd/Registax4/PSP8 ALPO Member #4287 Post Extras:       Lunatiki Pooh-Bah Reged: 08/07/05 Posts: 1252 Loc: Amarillo, TX Re: Jupiter 08-26-08 Europa transit *animation added* [Re: Lunatiki]       #2611602 - 08/29/08 11:05 AM Edit   Reply   Quote Quick Reply   Well, I looked at it from a 3rd computer screen, my wife's laptop, and I certainly do see a halo when I move the screen to the right angle.
