.....just for others following this particular aspect, here's one of the above R6 Mars wavelets (same values) using larger AP's centred more within the panet's disk and using slightly larger ones at the poles.....as Emil suggested, but now 1500 frames.

I'll work back through and (eventually!) post these nights' images of Mars and Saturn with both MAP's setups and results as well as "Edge" qualitor estimator.....I didn't bother about reducing the size of the whole box as my 8-thread machine makes mincemeat of the processing speeds anyway....!

One (small) frustration I'm having with the program: I'm finding it impossible to select certain image sizes with the width/height sliders. It would be great if there were text boxes where the numbers could be entered as well as the sliders...

[Sunspot]

I'd second that suggestion.

I'll look into that. In the meantime - and perhaps it's already good enough - if you click on the sliders, you can then use the left and right arrow keys to move the slider. It will be much more accurate then.

Once I found a particular image size that I'm going to use more often, I simply click the 'remember' checkbox, and each following set of images will be cropped to the remembered dimensions.

[Sunspot]

That certainly makes it much easier to set an image size. Thanks for the tip.

Thanks, Emil -- that's what I was looking for. It's not very easily discovered, though. Having something more standard may save you being asked the same question in the future. And yes, the remember checkbox is great, but may not help if you're going from imaging Mars, say, to Jupiter with moons...

Also a very useful feature for processing frames for animations...

I'm getting great results from this software - thanks Emil.

Awesome work Emil. AS2 works very well. Here is a little comparison I did with some data I have.

I think I am liking the AS2 / Astraimage combination best so far.

Cheers!

Interesting. Looking at the colour images, I see some parts looking better with Reg6, for instance the barge, also the turbulent trail behind the GRS as well as overall in the equatorial region. Yet, the polar regions look better in A!S. The GRS itself is a tossup to me. This is the same sort of results I've been seeing with Jupiter as well.

I agree Paul, it is a close call between the two. I will say a lot more effort went into the R6 version. Wavelets in R6, unsharp mask in PS, and then astraimage in PS, whereas the AS2 was just AS2 and Astraimage. They both do an excellent job of stacking, that is for sure.

[GreatGigInTheSky]

David,
Would you mind sharing what processing you're applying in Astraimage? I assume it's some flavor of deconvolution. I've been wondering about the possibility of skipping Registax completely when using AS2 for stacking.

[Rankinstudio]

Hi Jeff,

I am just using the wavelets in the astraimage PS plugin. I usually start with the large details then work up the finer detail sliders. Not using the deconvolution.

[Asimov]

Emil. I'm just getting around to trying AS!2 on some Saturn data. I'm finding it almost completely obliterates the Crepe ring. Only a very small portion of it is visible. I've tried stretching it of course in the low, mid & high levels in all my editing programs including Registax. Even before using Registax waveletts it is not visible. In this particular example/AVI it is there in the RAW data as well as after aligning/stacking in Registax.

Any help would be very much appreciated as it gives a MUCH superior stack to Registax apart from this C ring problem.

Hope you can take the time to look at my thread again Emil and see what you can make of my questions to you therein...

John, can't help you at all except to say that I haven't found any problems with AS!2 and Saturn's Crepe Ring.....except to say (and I'm sure you'd appreciate this already) that gamma levels influence the Crepe Ring very significantly - but AS!2 shouldn't have any influence there on what you bung in.

[Asimov]

I was about to ask you Darryl, as you're the only other guy here that (I thought) had Saturn data.

Yeah I know..about the gamma etc. Here's a registax version with all (mostly) the same levels etc. It's got me beat!

I guess I'll work it out - Gotta be something I'm doing wrong..

Could you post (or send me) the raw stacks?
Have you tried turning off the "normalize stack" option in AS!2?

[Asimov]

Can do yes.

"Normalize stack" was immediately disabled by me right from the start. I don't use that in any stacking program or procedure.

[Asimov]

Actually I have 75% solved it by stacking a final from AS!2 & 1 from Registax. I'd be much happier that it didn't happen at all in AS!2 naturally. Image sent BTW.

Hi Jeff - in defence of Emil on this point where you're referring to the use of the arrow keys on the keyboard to "fine adjust" the slider values, this is a standard keyboard operation (once you've clicked on the control) on just about every program application I know of.....not trying to sound clever, as I only discovered it about a year ago on something else and then found it was a universal operation almost.....

[GreatGigInTheSky]

Hi Darryl,
I take your point -- I've since discovered this in some other programs (Registax, Gimp on Linux...) -- I was just unaware of it. It's just my ignorance of UI conventions... :o

.....well, I was in the same boat untill I accidentally "discovered" it awhiles back Jeff - in my case, so much to learn, so little to fit it into..!

ps: talk about ignorance - what's "UI conventions"..?!?

[GreatGigInTheSky]

Darryl,
UI = User Interface. So UI conventions being the standard ways that users can manipulate controls. And you think I would have encountered this before, being a computer programmer by trade, but I work on web sites doing generally back-end server stuff, so I'll have to beg pardon on that basis.

[Sunspot]

Emil,

As you know I drag and drop bmp files onto stacking programs (either Reg or AS!2). It seems that when I drop the bmp files on AS!2, the last bmp in the stack shows up as the first one on the display. Since I use Ninox to sort, the last bmp should be pretty lousy and the first one should be pretty good. I captured a screen to show what I mean. Be sure to note the slider position and the quality of the image. If I slide the slider only one image right, it goes from really, really bad to really good. If the quality of the first image has no effect on stacking, then it is nothing more than cosmetic. Thought you ought to know about it anyway.

Interesting Paul, so how do your Saturn AS2 images come out ?

[Kokatha man]

.....wonder whether this has anything to do with the "0000" - "0001" - "0002" sequence the ninox'd bmp's are presented as Paul - but AS!2 is going to do its own thing regardless (just as R6 would also) so I think it is probably a moot point...
