Test images taken with our 12.5" PlaneWave
Astrograph
In spring 2016 we
started operating a 12.5" Planewave astrograph in the 3m chameleon dome. The
11" Celestron HyperStar telescope mounted there until then was moved to the
transportable mount outside the dome.
In the last two years we have been
able to take many beautiful DeepSky pictures with the PlaneWave telescope.
After a collimation test, which was done with a video module, we took some test
images of the moon. The telescope has a focal length of 2.540mm (f/8) at 314mm
aperture.
All raw avi files were
exposed in primary focus with a Celestron video module SkyRis 445M and a Baader
IR passt filter for calming the seeing conditions 18 September at 22 o'clock
UT. 144 of 1,500 raw images were stacked.
Despite the large obstruction caused
by the secondary mirror, we find the picture results extremely convincing. All
pictures can be enlarged by clicking on the thumbnail. |
