Hello,

 

A few years ago i started programming functions for astronomical image processing.

Since two years i share a software that works for Windows : AstroSurface.

 

It is still in evolution, the actual version is : AstroSurface LEDA.

There is a new version every month or so

 

You can find it in my site : ( avoid the 32 bits version that is obsolete )

 

http://astrosurface.com/pageuk.html

 

A powerful method that mix Wavelets and Déconvolution is integratred.

 

I hope you'll enjoy it.:)

Hi Lucian, I just ordered a camera and picked sharpcap and astrosurface to learn, initially had trouble opening the program but I finally got it working and just wanted to say thankyou, watched a few tutorials and plan to use it for the moon and planets , Scott

Lucien,

 

I've been playing around with AstroSurface and I must say you've done a fantastic job. You have a lot of really cool features that are well thought out and more importantly appear to work quite nicely.. All in all Astrosurface is a great tool to have in the toolbox. Well done.

Hello Brad,

Thanks a lot for your opinion about AstroSurface.

This tool is still in evolution and i'am happy to have qustions or remarks about it.

Hi Lucien,  sorry but I am not understand how to use it.     Its beyond my knowledge, I was hoping to just take an already stacked image (PNG) out of Sharpcal and try and improve it but the tutorial for your M15 example does not match what I am seeing with the program.

 

Hopefully someone might create a youtube and explain what they are doing for folks like me who don't have the background level of understanding to follow what the SW will do.

 

Thanks

Don

There are several YouTube videos showing some basic stuff but it would seem there is always a learning curve, I have 3 programs to learn to get in to this, one for capture, one for processing and this one for stacking, from what you said since your already stacked, your main interest would probably be to concentrate on understanding the wavelet part

Hi Lucian, thought of a question, so I am reading through all of the tuturals and needed an opinion, basically being told to capture the planets in Sharpcap raw8 in ser video format at about 2000 frames.... then suggested to move that file to the pppi program for debayer  and alignment.... so the question is, will the pppi program be nessasary or is astrosurface capable of doing all of that, I’m just trying to understand.... I know most people use multiple programs but just trying to get a grip on what I need.... for example I know lots of people use registax solely for the wavlet part, but since you have wavlets too then there would be no sense using that program, thanks

Hi,

 

Don,
I have this short manual to help in Wavelets-Deconvolution working.

Read it carefully and test it with some stacked images that can be downloaded in AstroSurface site.

 

http://astrosurface.com/pageuk.html

 

Come back here with some results to share if you want.

 

Here is the short tutorial for Wavelets-Deconvolution : AstroSurface LEDA.

Images to practice can be downloaded : in the botton.

 

Best regards,

Lucien

Lucien, 

 

I should be in bed right now, but I cannot stop experimenting with this tool. From what I can tell thus far, this is excellent work! As with any new tool, it does take some getting used to (everyone loves routine), but I think most of us will find it intuitive enough with a little experimentation. Again, fine work. Thank you! 

 

Regards, 

 

George

Hi Lucien,

 

Thanks for the new quick tutorial, it got me going so at least I could play around.   I used a PNG captured from SharpCap for the Eagle Nebula.   You can tell me which you like better the original or the tweaked one.   I still don't know what I am doing but at least I can do something now LOL.

I'm loving it already.

Compared to other expensive options I have attempted to use it seems very easy to use and produces very encouraging results.

The 7 page tutorial is great to get stated with.

Thanks Lucien - I am sure many appreciate you sharing this huge effort of yours.

 

And Don - I think the second image is better. It seems to have more contrast and better color balance, dark background seems a bit more black. I wonder if it needs a bit of sharpening as the stars look a bit fatter and the ones close together start to merge.

Cheers

Phil

Ok Don,

 

Images are thumbnails. But the second is better : stars are smaller and with best visibility.

 

There are many tools in AstroSurface for processing images.

 

When end processing deep-sky images, Wavelets-Déconvolution may be used with the range High (High, Std, Low).

With very fine details sharpening to reduce stars:    radio buttons 1 or 2 in Wavelets HF mainly or by Deconvolution with a small PSF (around 0.6 to 1.0 pixels )

 

Another way is to use the tool Noise : see button Noise ( or by menu Filters the Noise / Color Noise )

Here you can reduce noise and improve stars in the same time.

 

You have to experiment by yourself because Deep-Sky processing may be a complex job.

 

Lucien

Probably should make my question less long winded, is sharpcap and astrosurface all I need for a great out come on moon, planets and deep sky? , just struggling with all the overlap from all the programs available. Still waiting for my qhy462 to arrive so learning as much as I can

Ok,

 

With SharpCap and AstroSurface, you will have a lot of possibilities for Planetary and DeepSkt processing.

OK, I really like this software now.

I have spent about 20 mins and achieved these:

Jupiter 20200713.jpg

Jupiter 20200713a.jpg

 

I know these are not anything special, but like I said earlier I was not doing so well with other software options.

The thing I like about this software is I can do everything in the one package. The previews work well and for most things the mouse wheel works on sliders and spin edits and at the same time updating the preview live.

You really have done a great job Lucien IMO waytogo.gif

You should put a donate button on your website (am I allowed to suggest that?).

Cheers

Thanks a lot Phil. smile.gif

I will think about it

 

Some suggestions to improve.

Most of time the best is to do these ops  before "Wavelets-Deconvolution".

Thanks Lucien, I will try that tomorrow.

BTW - I was struggling to process the planet and its moon using other tools (probably my lack of technique), I could get one or the other but hard to get both - but for some reason this was very easy in AstroSurface.

I would be proud of those, perhaps not the most detail you could achieve but it’s a very nice natural looking image, which I rate equally important

Lucian , I have one maybe bug to report, however it could be my computer and it does involve operator error, if I click on one of the editing tools and then try to do the edit, I’ll get the normal window to pop up instructing me to draw my roi first, the bug is you can’t close the alert, or it gets replaced instantly with a new one which freezes everything, only option is to close whole program to start over, it seems to hang randomly, sometimes it will close normally.... I’ll eventually teach myself to draw the roi first but thought you should know

Hello,

 

The trouble is very strange and i can't verify it .

Try to load last version of AstroSurface.

 

What is your Operating System ?

It’s windows 10 pro running on an acer swift, no biggie since I just need to remember to draw roi to keep it from happening, I am running latest version, I can only speculate but it seems to me once you interact with the controls without drawing roi, what ever triggers that error message does not clear when you close the pop up, software loop of some sort, but intermittent, does not happen everytime

Tried Astrosurface on some recent captures and i really like its workflow, great work there Lucien!

Keep up the updates, i think it ll become my favorite one for planetary wavelets processing.

Im gonna study some more tutorial videos to improve my technique :)

I’m impressed too, I never learned the others so I can’t say much in comparison but Astrosurface gave me some very nice images my first time out so I am expecting even better in the future. I think people get use to what they have learned and don’t try new things enough, I’m guilty of this too but I am an astrosurface fan now and love it’s still under development
