This is not my data it is a vid from the youtube and I want to practice processing as I am getting a mount soon fingers crossed that is goto and tracking and I am going to start gathering data. So here is my process of this video. Attached is a screenshot of the vid and the processed results.
Hey Warren,
I've been wondering about this for a while. Using some vid of youtube and having a bit of a practice!
I have not done such a thing yet, but this has given me a kick.
The only thing I can think that would be a negative would be the quality and resolution. You are working with "second hand" data.....me thinks....
So the final result may not be as good as what you might want it to be.
Up side is that when you do do it for real.....and process it with the experience you have gained, it will look and be better I guess!!!!!! ))
Just my 2 cents
Cheers

I ran the vid through Virtual Dub to make Bitmaps than stacked the bitmaps using Registax and processed in Gimp.
I look foward to seeing if I can get anything off the SD card. Hey how come you haven't put any photo's of your trip that you had on your laptop on IIS for us to look at.
PS ...
And my appointments in the Townsville Base are 10.30 am for an MRI and 3.20pm at the Medical and Cardiac Clinic on the 27th of Jan hope to catch up while I am there.
Hi Warren, very good result there. Is there any reason you cut the vid up in Virtual Dub first. Does Registax not do a similar thing? Or is there some secret process you are harbouring?
Cheers

GIMP, OK, never had much luck with that either. I would love to be a better processer .... one day.
Ha, no piccies from trip = very slacko!!!
Bugger, no, will be in Victoria for your appointment.
Great idea Warren, I am going to use the same method. I am in the same boat as you, I do not have videos of my own to do it. I have only done stills to date. The other thing is I am new to Astro Image processing, used film to date, and I am totally confused by the number of packages I am trying.
Nebulosity – which I hate, sorry maker I am sure its good, its just me !
Registack – which is indecipherable
Gimp
Maxim DL – almost out of the trial license and have barely scratched its surface
Iris
Virtual Dub
Canon Digital Professional
Deep Sky Stacker – which seems easiest but does the least.
I have been using just the built in settngs not changing anything and just loading the bitmaps then clicking on align then limit and optimize and stack and googling for registax tutorial vid's. And I am using SuperC a freebie to convert the video's into avi files with mp3 sound as it is what Virtual Dub seems to like

Nebulosity is actually my favourite program, but for deep sky, not for planetary.
Registax is a better bet for the planets, and is hard at first, but maybe this will help to decipher it. Have a go at the Jupiter video.
1) Open the video in Registax and align on Center of Gravity with a threshold of 20 using Gradient2 and keep the best 70% of the frames.
2) Create a reference image using the best 100 frames and use slight wavelet adjustments to bring out the finer details without making image noise too appearent.
3) Optimise. Do not Optimise & Stack, just Optimise.
4) When complete, go to the stack tab, show the stack graph, and limit the stack to about 1200 frames limiting the differences mostly, but sometimes limiting the quality as well.
5) After stacking is complete, sharpen using Linear/Default settings, increasing the level 1 wavelets until noise starts showing up, then be conservative with the higher wavelets.
6) Download a Hubble or similar reference image of Jupiter (Just google one up). Use PhotoShop's Match Colour feature to make sure your image has accurate colours. This can really bring out the detail. Not sure if GIMP has a similar function.
This is the method I've been using, based on a technique from Jason, who gets great shots of Jupiter.
It is really good to be able to practice while you are waiting to be able to gather your own data. First on is the processed result and the second one is one of the bitmaps.
My first attempt using Registax and Maxons user guide. Pretty grainy needs lots of work, but i gotta tell you with all the options on wavelets alone it could take all day and night.
I had a go at all three, was really fun, I would have posted my results but I didnt save them. Ill be going out Friday night with the telescope so maybe i post my own data , bad seeing forecasted though :/
