Since three of our astro cameras are equipped with filter wheels, they can take pretty pictures -- this article shall be a short manual for this and it shall document our progress in the=is field. It shall still grow, get more details etc., so it's not considered complete so far. $>$ anonymous@undisclosed.example.com (Anonymous) Mon, 21 Jun 2021 13:16:19 +0000 https://polaris.astro.physik.uni-potsdam.de/wiki/doku.php?id=en:ost:ccds:ccdops&rev=1484357511&do=diff Controlling the CCDs with CCDOPS Preparations Mounting and connecting to the computer The CCDs can be controlled by the computer with the software CCDOPS.

For deep-sky imaging we use two QHY 600Ms, which offer, among other things, a full-frame sensor, very high quantum efficiency, very low readout noise, and a very low dark current. For these cameras we also have an off-axis guider, one filter wheel with 9 positions, and one filter wheel with 7 positions.$\mu \text{m}$$\mu \text{m}$$\mu \text{m}$$\mu \text{m}$$\mu \text{m}$$\mu \… anonymous@undisclosed.example.com (Anonymous) Wed, 01 Apr 2026 10:54:15 +0000 https://polaris.astro.physik.uni-potsdam.de/wiki/doku.php?id=en:ost:ccds:maximdl&rev=1773063018&do=diff Maxim DL Maxim DL is currently the primary interface used to control the observatory, operate the cameras, and perform observations. Interface and Basic Operation Maxim DL can be started most easily by double-clicking the Maxim DL 6 icon on the desktop or via the taskbar. anonymous@undisclosed.example.com (Anonymous) Mon, 09 Mar 2026 13:30:18 +0000 https://polaris.astro.physik.uni-potsdam.de/wiki/doku.php?id=en:ost:ccds:setup&rev=1617177208&do=diff CCDs Setup QHY600M * will follow soon ... STF-8300M First light Assembling the filter wheel and the OAG The goal of this task is to mount or dismount the filter wheel and the off-axis guider (OAG) to the CCD. The procedure in short: * to open the camera, loose the screws from the cover, see Figure 1. anonymous@undisclosed.example.com (Anonymous) Wed, 31 Mar 2021 07:53:28 +0000
