Some Solar System Activity
Which is more than I can generally say for us, considering the
COVID-19 shelter-in-place order we are now under. I have tried to
image more, but the clouds remain stubbornly close by, or in the way.
What I have this time is 2 images of the sun and one of a close
pairing of Venus and the Pleiades. Sun first.
Filament and barely visible plauge (very light area) above left of center |
In this image, which is a black and white image falsely colored
yellow, there is a filament, which is a prominence seen face on, near
the top, about the 11 o'clock position. It is the dark-ish line
that's not very big, or dark, for that matter. BUT, and that's a big
but, it's there. That's pretty much the 1st thing
I've seen this year on the surface of the sun.
Prominence on right. |
This image, shows a small prominence on the right side on the sun, as
oriented. Believe it or not, the yellow is the same as in the
previous image. However, I had to considerably lighten this image to
be able to see the prominence, so the true yellow color shines
through.
Venus "in" the Pleiades. Taurus and Aldebaran to upper left. |
And finally, last night, April 3, 2020, there was a close pairing of
Venus and the Pleiades. This is a single photo with a small amount of
“correcting”, basically to make the sky a little darker. This was
shot with a Canon Xsi DSLR, which is a fairly old camera at this
point, especially for an “astronomy camera.” It's a 5 sec
exposure using the 18mm-50mm “kit” lens. Viewed like this, it's
not too bad. However, I have an extremely hard time focusing the
lens; extremely small movements of the lens changes focus. Add to
that the extremely small image of Venus (by far the biggest and
brightest object seen) on the camera screen, even at 10x, and focus
is not seen until the image is out of the camera and on the computer
screen. Or, in this case, “out of focus”, is not found until the
image is viewed on a computer screen where I have the ability to
really zoom in on it. A good solution would be to have a different
lens, but I can't justify that at this time. Maybe later; much later.
By the way, if you zoom in really closely, you can see that the stars
are out of focus and that Venus has a slight halo around it from the
high clouds in front of it. Thicker clouds are just off to the right
of Venus in this picture; I darkened the photo enough to hide them;
well, almost, it is just barely visible. Also, in the upper left
corner is the constellation of Taurus. The uppermost orange looking
star is Aldebaran. The “V” shape is the asterism called “The
Hyades”, which is an open cluster of stars. A longer, guided,
exposure would show many more stars in this open cluster.
