Our large instrument rotator with 4-inch free internal diameter allows you “rotation positioning” of the connected recording equipment conveniently from your PC. Once an astrophotographer works with the Alluna instrument rotator, he will never want to do without it.
you like to display the Pleiades in landscape format, as vertically the
Pleiades unfortunately do not fit in total onto the CCD chip? What do you
do, run to the telescope, open the clamp, rotate the camera and hope that
now the angle is right, close the clamp and back to the PC .....
click an arrow key on your PC an arrow key and let your recording equipment
exactly position itself to a 0.01 degree angle without compromising the
telescope by touching its orientation. Or do you expose the desired object
further at the point where you last had to cancel by simply entering the
last used shoot angle and automatically start up using GoTo. And for visual
observation, you can also set a more comfortable viewing angle, of course.
The instrument rotator was developed specifically for our large RC systems.
The connection is made, as well as the focusing system and temperature
control directly on the Alluna Telescope Control System (TCS). There is
thus no further USB cable required from the telescope to the PC. The rotator
fits into the overall system.
TCS software includes everything needed for comfortable and precise control
of this extremely helpful tool for astrophotographers. The instrument rotator
can be positioned manually in both directions using 2 arrow keys, or automatically
via GoTo. The resolution is a 0.01 degree angle. You can easily input in
the "Target Angle" the desired target angle, e.g. 271.5 ° and then
click on GoTo. The instrument rotator now positions your connected equipment
at a maximum speed of approximately 5 °/sec. During positioning (manually
or automatically), a virtual CCD chip in the rotator monitor rotates simultaneously.
A quick glance at it and one immediately knows how the camera is positioned!
Since the software has stored the current rotator angle, a reference run
is basically only required for initial commissioning of the rotator. Any
further reference run, however, can serve to maintain the maximum positioning
accuracy over many hours of operation.
With a vignetting-free inner diameter of 100 mm and a superior stability, the rotator is also suitable for large and heavy CCD cameras and instruments
course you can also use the instruments rotator via the integrated ASCOM
interface and run Astroprograms such as MaximDL or CCDAutoPilot with the
Large, vignetting-free and accurate positioning, even for heavy CCD cameras our instruments rotator for astrophotography.
