Hey all,,
I ran some Avi's last night with the newly received Zwo Asi - As a testing I think the camera ran fine in Firecapture. apart from a couple small issues I ran approx 10 or Avi's to compare and familiarize with the interface.
I am posting these rather dodgy results from stacking & Processing - wonder inf any have come across this situation before ?
Appears to me that there are some remnent of allign boxes not blending into the rest of the image properly ??
Using AutoStakkert seems to produce a rather smooth stacked image Tho when stretching wavelets in either PS or Registax, there comes these box or half box artifacts, !
These are happening in different amounts and quantities, and show up in all !
May have missed downloading AutoStakkert properly, could be just an effect of bad seeing , planets were jumping around a bit, Currupted download ?? ? !!
Thanx Nik, Glad to hear it is most likely a common thing. There was a huge Jet stream at the time - I noted 225Km/h in the 250 hPa levels - wouldN't have helped, Mars was looking like an egg rolling on the ground - hence the outer areas of the disc being susceptible - I gather/guess !
Looks like something to do with settings on Autostakkert, and I don't think it's seeing. I've tried it a few times and quite often get similar results, in a way I don't typically get with Registax. I feel like I must be doing something wrong (many others use Autostakkert to great effect), but I'm not quite sure what...

Yes, this is my 1st of thoughts, the squarish artifacts size is very similar to the align box size I used - must be related in some way - could also be a bit of both, the wobbly seeing could be confusing the alignment box intensities, - I did raise the intensity value of the align boxes to bring/congregate them more to center of Mars but this didnt help if any - mmm, come to think, maybe need less intensity value as to cover the Limb further out - so to speak !
Ill must give this a few more goes, (tomoro - need early night) play with AutoStakkert settings further, only used it a few times to date ..
Cheers for all that Andy

Yes same here Nik, so, to me, is why I suggest it could have an element of the 'seeing' effecting the quality, only guessing at this stage.
I captured 10,000 frames in this Run, did a stack of 5, 10, 20 & 40%'s and the squarish artifacts showed up in all and in all the same places ?
I should try some further Radical align box combinations
try running the video through Pipp first which stops the image shift as it can stabilise the video first then use default settings in autostakkert.
Sometimes default settings are a great fallback. https://sites.google.com/site/astropipp/pipp-manual

Thanx Nik ,,
AutoStakkert has an Image stabilization process init and appears to work fine when slide through the frames or play it, just thats mars looks like an egg rolling, or should I say 'spinning' kind of !
I may try Pipp down the track if I dont give up before then
Well, how many variation can one use in AutoStakkert, Lol !
wont go there, Lol but here are some more results, over exaggerated to show betterra !
Any-which, I should try, oh, will try running alignment and stack in RegistaX see if similar occurs - if so, Then I'd be pretty safe assuming these artifacts are results of just bad seeing conditions, poor quality capture Avi !
Interesting experience none the less !
These are artifacts from Autostakkert merging multiple alignment points. Not related to seeing. Try using larger alignment points, preferably selected manually, and less of them. I found this helpful: https://www.youtube.com/watch?v=Ci_a...utu.be&t=6m34s

Yes Thanx Graeme - I watched them a few times now - just still learning the ropes. How-ever, with you now pointing it out at this time, I am assuming that the settings & parameters can be difficult to categorize for different planets, scale size of capture etc Need to dabble more - yep
Nice Point

Ok, I have run through Registax a few times and it is atleast spitting out a rounded Mars with a pretty smooth finish Though not achieving as sharp a detail as the Autostakkert stack ?
Oh, will have to downsize the Tiff files for posting - hang on
1st two are snips of the near worst & near best frames of the Avi Vid - not to great hey, but as mention, test for 1st light - camera !
3rd is a Regstack
4th is the above with wavelets
5th is another Registack
6th above with Wavelets
All quite rough as reckon the quality 'seeing etc' is just not good - just experimenting

Reason: add pics

I was thinking of manual points actually, but not for long, as thinking that too few were not advised -
If I gave 150pixel align points It would create only 6-7 of them- prob a good amount but they wereN't covering the whole planet, maybe 70% of it leaving large amounts of Limb uncovered ?
So, Ill give the manual a Go
Thanx again !
Well well, I have it sorted in AutoStakkert now ! Definitely have come to the conclusion of problem being me and my Alignment Points
Thanx due to Andy & Graeme and I believe other influences do have there place in here - Programs have quite amazing capabilities when one puts some time toward experimenting... speshly along with recommended advice & Input
Guess Im ready & Waiting some clear steady conditions again
Pics:
1) Bad Avi Frame
2) Good Avi frame
3) Align Points
4) Stack 5% of 10tho
5) Ok Final
Making progress. Just a note about your 3rd pic above, The creator of Autostakkert recommends not placing alignment points near the edge of the planet.

Cheers Graeme .
Funny that - initially when had the limb uncovered in places with align points closer in from the limb, appears to have created the mishaps, but not sure if directly related to where limb was not covered by points ?
Maybe due to being such a wobbly planet, may have needed the extra coverage ? mm , could/might try again to clarify
Thanx for the Link, Read, some good further info there, the last page has some very good insight tips
