AstroToaster Download


I wrote this application to allow me to Observe DSOs using my DSLR,  I enjoy watching the image develop out of darkness as the light is collected. ( AstroToaster is a newer version of the "Observing ToolBar for DSS", it is now a free standing application and does not need DSS to be runing )

AstroToaster  is a freeware application for obtaining semi-live views of astronomical images  using a DSLR,  CCD  (or any camera that can produce static astronomical images)

AstroToaster uses the  Deep Sky Stacker (DSS) Processing Engine.  It accomplish  what DSSLive does, but using the full capabiblities of DeepSkyStacker, and has a Viewer with easy to use color and light enhancement tools.

        - The camera drops image files into a 'monitoring' folder, and they are automatically processed and continuously stacked
and updated into
           a viewer window
        -  You can use darks, flats etc.
        -  Color adjustments, levels, curves are re-applied automatically
to the refreshed image in the viewer
        -  It performs a complete align and re-stacking of the images instead of a running average
        -  It uses DeepSkyStacker's engine and settings, to perform the processing
        -  You can edit and tweak, stacked images from earlier in the session, while acquiring and processing a new image 

DeepSkyStacker is a freeware program developed and maintained by Luc Coiffier, which you can obtain from his website
It allows you to add data from many faint exposures, through a process know as aligning and stacking to produce a much sharper and intense image.

Once you  learn how to use DSS and get it working nicely for your camera, and setup, there is no reason you cannot obtain the same results while using it for live viewing. In the viewer the images can be adjusted to a quality similar to what can be accomplished in a brief Photoshop session.

The screen shots below are of the raw Filelist processing page, with the colored toolbar on top, The image on the right also shows the drop down viewer and color adjustment toolThe Toolbar collects images from the camera for DSS to process, and displays the results in an adjustable viewer.

I have found this to be a fun application for astronomy,  you can download
