Hi all

Got about 10 minutes of good seeing this morning, after Saturn rose above 24. Luckily I was out there, ready to capture, with no jetstream over coastal NSW!

It seems I may have captured some storms/spots as seen on the red channel (and highly processed cutout on the right).. It may be artifacts but who knows :) I'll check some other avi's and see if it appears on those too.

Captured for about 1:20 for each colour channel, with the 10" dob, 5x powermate and DMK21AF04 @ 15fps. Gain was at maximum (100%). Stacked 300 frames in each channel for the final result.

Wavelets processed in registax, followed by mild ME deconvolution in AstraImage, and final curves and levels adjustment and noise reduction in Photoshop.

Really happy with this image, it's by far my best Saturn image, especially given the low altitude and brightening sky (30 mins before sunrise).

Thanks for looking, comments welcome.

Beautiful Shots!
Awsome detail that you have captured.
I cant seem to distinguish the spots in the red Channel, it may be that my sight is failing me or that my Monitor settings are not set to optimal.
It really doens't matter though, they are impressive indeed.
Have you done Jupiter in the past?
with the detail that youv'e captured on Saturn you shots of Jupiter must kick some A**!

Thanks Dennis and Phil.

Dennis, I've done a lot of Jupiter :) We're lucky to have had it up high in the sky this year which helped a great deal.

Here's one that made APOD :) http://antwrp.gsfc.nasa.gov/apod/ap060318.html

and i've attached a few others..

There's also some animations I made, at the bottom of the article I wrote on planetary image processing:

Thanks!

Beautiful Saturn, Mike. :dance:

Dennis, you can see a bunch of Mike's animations on this BAUT search page: http://www.bautforum.com/search.php?searchid=247532

Those were pretty cool, too. Definitely worth looking at.

OMG!
I am completely Blown away!
The detail that you have captured is stunning and beyond words,
I am Jealous, and I wont even attempt to post my miserable result of Jupiter that I took a couple of years ago with a 4 inch Achro and the DSI one shot
totally awestruck,
Dennis :)

Ooh nice. Once I save enough pennies Im going to get a dobsonian and start doing some photography too. Currently getting to know the sky with a meade etx-90. Of the planets Ive only seen Saturn well the rest have been to low on horizon. Guess I picked the wrong time to buy my 1st scope:wall:


So you can take decent pictures with a Dobsonian. Could you give me more info on the mount you use I.E cost wise

Fantastic Work Mike!!
Your images look as if you have been floating in space above the atmosphere!
Congratulations again.

Those are great!
That's the first shot of saturn I think I've seen this season so far. Those rings are sure closing up from the last time I saw it.
I really like your Jupiter image. Even though I had a lot of clear nights here last summer, Jupiter was just too low to get through the atmospheric crud on most nights.
Here are my best attempts:
Yes, I know....it's kind of a strange color.

Wow! I am really just blown away by these images. I feel like I am doing a fly by when I look at them!

Thanks for sharing!

That's incredible detail...

I tried using a Meade LPI several years ago and I could get nowhere near those results (see attached). I can't wait to get my new scope (10" LX200R) which will help with polar alignment and tracking. ;)

Hi Mike.
Great work. Your Saturns and Jupiters are the best. Thanks for sharing.
