Aquila/Milkyway movie with annotations
« on: 2010 April 19 09:37:23 »
Hi,

I did another experiment with the data that I obtained for http://pixinsight.com/forum/index.php?topic=1328.msg6827#msg6827 (basically, 180 unguided 30 second shots with the 35mm kit lens of a Canon EOS 40D, shot through my roof top window).

-I created a short film from this after some basic processing (HistogramTransform etc.) using Windows Movie Maker. You can nicely see how the sky moves, and it also demonstrates the the Canon Banding noise problem  :yell:. See http://cid-c56e60845cfa6790.skydrive.live.com/self.aspx/Pixinsight/Film_unaligned.wmv (12 MBytes)
- In addition to the basic processing, I then sent the whole data through the Canon Banding script (bug fixed version, see http://pixinsight.com/forum/index.php?topic=1159.msg9587#msg9587). Additionally, I sent the whole image stack through a program that automatically labels constellations, stars etc. . The whole process ran without any intervention on a 2 GB Linux system using PI 1.6 (something that was impossible with early I 1.5 version due to memory leaks). The result is on http://cid-c56e60845cfa6790.skydrive.live.com/self.aspx/Pixinsight/Film_annotated2.wmv (40 MBytes)

You can nicely see how the Canon Banding script removed much of the annoying Canon Banding, and you can also see how the labeling program (mostly correctly) determined the picture coordinates, labeling constellations, stars, and NGC objects.

A nice result...

Which program is it that you used Georg?

(I haven't had a look at the movie yet - I'll do this back at the main machine, where 40Mb downloads are less of a problem ::))

Very nice work, Georg. Your script has worked close to perfection; I really feel guilty for not having included the latest version in PI 1.6.0 ...  ::)

No problems Juan - you said that v1.6.1 is only a few weeks away . . . . . ::)

I created an integration of PixInsight and the "Blind Solver" of Astrometry.net (see www.astrometry.net for more). This is a truly amazing program when it comes to finding the location of an astronomic picture. See the attached annotated image (just a quick stack of some of the 35 mm shots). The blind solver correctly labeled it despite the use of unguided pictures and a 35mm lens with rather bad distortions.
