Recorded with a PST-DS and DMK31AU03AS camera.
This shows about 5 hours accelerated
in
a few
seconds. Each
movie of 60s was registered with Autostakkert2!, then about 300 PNGs
were registered
with RegiStax5 and saved as a movie. This is a crop around
the filament and sunspot AR2010 showing how it disappears !

I was taking surface images for a mosaic and when done told to myself
lets have a look on prominences ! I am glad I did !
Fluorite 102/900 refractor, JMI electrical focuser, SM90 & T90 BF30,
1.6x Antares barlow, ASI120MM-S
The first part of the animation is done with 30 individual movies thereafter
I switched to 15s as I saw it was moving very fast.
Because of high clouds (from numerous spread contrails) a few
frames have been deleted : 317
Frames
out of 324
Recordings started at 12:20:45 UT and were stopped at 14:06:46.
About 570 GB of disk space have been used for this work ...
Each individual 16b AVI taken with Firecapture was registered with AS!2,
keeping 95%. Resulting images (not all the same size) were converted
to 8b with Irfanview. A first alignment was done in RegiStax5 and save
to
a
cropped
movie. VirtualDub was then used to delete bad frames and crop the black
stripes. RegiStax5 was used again using "align with processed" a few
times. The resulting AVI was loaded in Virtualdub to change
framerate from 300 to 24. "WonderFox Video to GIF Converter" was used
to make GIF files of different frame rate.

It was very nice as happening on the rim of the Sun then showings lots
of details !
Activity of AR2290 started to be intense soon after 15 UT as seen on
the top right of the B&W picture taken with the ASI174MM. I then
changed for a camera with a smaller sensor to get more details ...

NOTE : A few hours later departing sunspot AR2290
emitting a M8-class explosion almost crossed the threshold into
X-territory. NASA's Solar Dynamics Observatory (SDO) recorded the extreme
ultraviolet flash.

Magnetic Arches following
a huge X17+ flare which occured on the 09/07.
Original capture rate is 1 saved image every 20s.
The poster on the right shows the processing of
the still image in PSP :
1) Original output AVI image (resulting of internal
addition of 100 with negative guiding on sunspot in Astrosnap)
2) multiplication of the image by itself, divisor 20 to improve the low
intensity prominence
3) multiplication of the image by itself, divisor 250 to improve the high
intensity disk surface
4) Image 3 is glued on image 2 but without fusion, then using the rubber
with this configuration and care, the
lower layer appears slowly as shown (half done)
5) resulting B&W image
6) colorisation, slight sharpening and slight contrast increase.
After the colored image is loaded in Neat-Image
for noise reduction. |

Eruptive Prominence

When I installed the Perl-Vixen Fluo 102/900, Coronado
SM/TM90 just after the Sun was in view of my location, I did not expect
such a view ! Is was really spectacular. Istarted racing to put the vestaPro
and parameter AstrosnapPro ! Images in integration mode (50 frames at 10fps)
with the B&W sensor modified ToucamPro, adding automatically 1
frame to the AVI every 50 frames for more than an hour the clouds became
more and more numerous rendering the work very difficult. In the long
and complete version
you will see that the begining of the AVI is not live convoluted then
the rest is. If you are interested in precise timing here are the rush AVI
file and the text only data-file |

Perl-Vixen Fluo 102/900, Coronado SM/TM90.
AstrosnapPro in integration mode (200 frames at 5fps) with the B&W
ToucamPro + contrast baader filter, aligning and adding automatically
1 frame to the AVI every 100 frames for about 80 min. AVI has been realigned
in Registax3 and save in maximum mode then colorized using the process color
functions of Aviedit & matrix enhanced (4-3). About 120 frames (original
AVI is 126 frames from 10:45:46 every 37s but some clouds made a hole of
a few frames). |

A not so quiet prominence ! Perl-Vixen Fluo 102/900,
Coronado SM/TM90.
Looking at the telescope, there was not much to see... it was really steady
! Nevertheless as it was not so small, I decided to make an animation in
case it would change ! I used AstrosnapPro in integration mode (200frames
at 10fps) with the B&W sensor modified ToucamPro, adding automatically
1 frame to the AVI every 200 frames for about 2 hours. The lens of the 2x
Apo Meade Barlow was screwed in front of the BF15. Later AVI has been colorized
using the process color functions of Aviedit (blue to 0, green to 30%) and
exported as new AVI and Gif. On the right, a single image from the animation. |
