Tutorials and Processing Examples / Re: PI Tutorials from Warren Keller and Rogelio Bernal Andreo

« on: 2013 March 26 13:02:36 »

I just bought the DVD and it arrived a few days ago.  After over 12 months of rain and cloud i have had no imaging done but i am sure to put this to good use.  its great to se the positive results from the tutorials - it shows promise for some one as thick as me!

wow fantastic work - this would be so good showing people items you can capture.  Look forward to a finished version

dont worry - i found a video from Harry where he did a HDR and noted he did a registraition process for it.  after a few attempts i worked it out

General Discussion / its been a while - how can i get my images all the same size/registration 4 hdr

« on: 2012 February 28 12:49:11 »

This incessant weather on east coast of Australia is driving me nuts.  There were two clear nights last week when i was able to test my new Meade 14" and titan mount.  I was going to do eta Carina but then changed my mind and went after M42 before it was out of reach.  I had to image it at least once this summer.  My problem is that during the image gathering process the images i gathered for 5sec, 15s, 30s, 60s, 120s and 300s were all over the shop - guiding errors that i discovered were introduced when the dome covered the guide camera -( moving the scope when it went for a search) so my images were slightly out of sync.  now with this new version i know that you need the hdr component images to be the same frame - which i haven't got - exactly.  how can i crop/align all of the images to be the same size and alignment?  the shots are samples only to show the delema i have (LOL i picked a bad one for the longer exposure - sorry)

Tutorials and Processing Examples / Re: Dynamic Range and Local Contrast

« on: 2011 September 25 00:43:25 »

Hi all,

I've just published a tutorial about processing techniques concerning dynamic range and local contrast. Although it's an advanced tutorial, I think some sections can be easily followed. In this article I describe some techniques that are extremely important for me at this moment. I recommend to take a closer look to the star dynamic range compression section that speaks about the techniques I am using now to restore the Gaussian profile of the stars. Follow the below link to read the article:

Hope you like it!
Best regards,
Vicent.

great article and hints but i cant get the mouseovers to work Vicent?

New Scripts and Modules / Re: Gradient Domain Operations, take 6

« on: 2011 August 17 11:59:25 »

to be fair i havent watched the video yet, but i did assume it would be similar to doing a mosaic the old way where the orientation or size isnt that a problem.

With this version of the tool, GradientMergeMosaic leaves the task of finding the correct positions for the mosaic tiles to the PI StarAlignment tool. The aligned tiles can then be merged using GradientMergeMosaic. Harry's video (and the online documentation, try the help button on the bottom right of the GUI) should be helpful to understand the workflow.

Georg

thanks Georg, will read up fully

Hi,

after doing StarAlignment as shown in Harry's video, you should end up with identically sized images.

The code explicitly checks that images are the same size. It is not clear to me how the tool should handle differently sized images: At which position of image 1 should image 2 appear? Or should one of them be rescaled? Which one? For the moment, I would prefer to stick with equally sized images (just as ImageIntegration does).

fantastic work guys, however i found a bug, it doesnt like different sized images form the same camera (cropped the stacked images)

Workshops and Conferences / Re: PixInsigth workshops and presentation at AAIC (not AIC, the "AA" is not a typo)

« on: 2011 July 13 02:52:44 »

I hear that Rogelio was a hit and a half!!?

Where do you hear those things?  All I heard is that it went well, which to me, it's good enough!!

The Sunday talk was a trimmed version of my talk at AIC 2010. The Friday workshop was brand new and rather improvised, believe it or not (proof of that was when I tried to do the HDRComposition and Mark's PixInsight's version was just old enough NOT to include that module ).

The "thing" that went on towards the end of Sunday... Well, that was just silly. I accepted because I didn't know how to say no. Of course, it would have helped if the data hadn't been pre-stretched (and seriously posterized) 

from a few who attended the event - since i couldnt be there.  i am not sure what you are talking about the "thing" - is that the event?  Anyway from what I can gather you have made a very strong impression on quite a few people - so if you wish to measure success with influence and knowledge i think (from what i heard) it was extremely successful, dispite the wardrobe malfunctions!

Yes, I'll be at AF Sat through to Thur night, packing up Fri David.  Will hopefully get time to play developing some days.  I'm no guru just for watching, but a quite a few things made me pricky my ears up.  For example, I've always struggled to get the things I wanted masked propertly in PI, and little things like watching Rogelio select/deselect layers in ATWT with the Preview turned on were a bit of a d'oh! moment.  Surely some people must have been gobsmacked by HDR wavelets and mosaic functions too.

Like most software I guess, you generally learn something watching a proficient user at work.
I wasn't video'ing myself sorry.  There is supposed to be a DVD but R was working fairly adhoc by his own admission.

great news.  hey i wonder how many people will have downloaded and bought PI after the conference, I hear that Rogelio was a hit and a half!!?

Well I'm happy to say I WAS in the front row watching Rogelio do his stuff for 1.5hrs this afternoon, and man does he know his stuff.   
I think more than a few copies of PI may have been "sold" today too actually.... 

Hey Rob i so wanted to be there this weekend, did you get a video of the session?  I am glad that a few people managed to see how an expert handles this package rather than the simpleton like me when i was at astrofest last year.  will you be at Qld Astrofest in 2 weeks?

thanks Carlos - very quick response.

for a newbie how would i go about weaving the magic?
