Cygnus 70-Panel Gigapixel Mosaic, by Kees Scherer
See this image in high resolution
For this Mosaic I used 70 separate stacks (also made with APP) with integration times between 45 and 345 minutes each depending on the object in the frame. An all new mosaic registration algorithm was used that is capable of truly sub pixel perfect registration of these large Mosaics. And the whole process is fully Automatic. The full size version is 29320×35386 pixels giving 1038 Megapixels.
That is not practical for web use, there is a selection of sizes selectable on Flickr and Astrobin. You can download the 50% version by selecting the download link on Flickr.
Processing: only histogram stretch and curves adjustments, nothing else.
The Fits file size of the full version is 3.7 Gb.
Equipment: Esprit 100 Triplet APO f5.5 telescope and QHY16200 CCD Camera cooled to -20 C with Baader 6nm H-alpha filter.
