Solar Video, April 3, 2004 with Sony TRV25 through ETX70
|I hoped that video may help to workaround bad seeing conditions in a day time. It didn't work to my expecations. A rather windy day was not giving a break: the image was shimmering all the time, the scope was catching quite a bit of wind and was shaking. The entire assembly with the MaxView and the camcorder was too long and heavy. It was bending enough to distort field of view and the camcorder was catching some of the internal reflections. So the session was not very successful as far as sun spots were concerned. However I accidentally got an image of a plane passing between the scope and sun.|

Below is what I pulled out from the Canon G3 images shot on the same day. RegiStax failed miserably when I tried to load five 4 megapixel 16bit tiff images. So I did some manual processing in Photoshop. Stacking turned out to be a bad idea since the images were distorted by atmosphere pretty badly so the features were not lining up well enough to bother. The resulting image is not as good as that one shot earlier, in October last year (see Gallery).

|Registax showed quite a bit fo limitations when I tried to process Canon G3 hi-res full depth images. The area to track the feature was not big enough. On few loads the program crashed. Wavelet enhancement on hi-res images didn't work as well as on low-res images. Manual stacking was too tedious on hi-res images so I gave up and picked one image that looked somewhat better than other.|
