Sun in H-Alpaha on July 15,
Sunspot Group 0963
First astro "light"
for the modified Pro 9000 webcam was the Sun. Images were taken
with an Orion ED80 refractor equipped with a Coronado 60mm H-alpha
filter. For surface detail an exposure setting of 1/1000 sec was
used and for the faint prominences an exposure setting of 1/100
second was used.
Seeing was poor.
Open Video Capture software was used to capture
30 second AVI files at 1600 X 1200 pixel resolution and 5 frames
per second uncompressed. There were no lost frames during the
capture. K3CCDTools was used to export the better BMP frames from
the AVI files.
One frame was used for
the surface detail and one frame was used for the faint prominences
and these were layered in Photoshop for the final image.
The 1600 X1200 image was reduced
in size for display below:
