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. |

Sony TRV25 camcorder, telescope Meade
ETX70, MaxView adapter with digi-T and stepping rings
from Scopetronics. A still frame from a video,
deinterlaced in Photoshop. |
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).

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. |
