• translate and extend Seite zum C8
• fill the “To be continued” (german: “Kommt noch”) spots in the Wiki with content

• fix tracking error / Mirror flop? (see autoguide speed and follow obj )
  • new tracking-test necessary
  • switch A-PEC and Dual tracking on
    • new training of A-PEC → detailed test series
    • make Backlash Adjustment
    • A-PEC seems to reduce the problem (see here) but one of the axis still seems to have a backlash
• Clean Schmidt-Plate! - How? → Maybe wait for next telescope
• complete list of problems (german: Fehlerliste)
  • observe and record behaviour/problems of the dome
• test ST-i camera with both spectrographs → Documentation!
• enhance collimation of the C14 see e.g. here
• train fine focus?
• test the new filters of the STF-8300 in comparison to the old filters of the ST-8
  • use Baader 2“ UHC-S/ L-Booster filter for C6? → filters are ready to test
• check old power adapter
• paint inner gate white
• test UHC-S filters with the ST-7 → Documentation
• clean oculars with Optic Wonder → last cleaning may 2018
• make pinholes
• tinker sun finder for C8

• bake drying granulate of the STF8300M (once a year) → next replacement: December 2018
• bake drying granulate of the ST-8 (once a year) → next replacement: Januar 2020
• bake drying granulate of the ST-7 (once a year) → next replacement: Januar 2020
• check drying granulate in the telescope – last replacement: 07.01.2019
• clean dome (see) → next cleaning: summer 2019
• In autumn, reduce the worm's contact pressure on the worm wheel of the right ascension drive to avoid the “ship horn” (see). In spring, increase the pressure again such that the right ascension axis can't be moved by hand.

• install Linux on the old Laptop to test alternative softwares (e.g. this here) in comparison to the existing installation
• SBIG: update driver and software

• extend observation lists in the svn
• revise presentation key points
• create mails for presentations → Copy&Paste
• translate svn:
  • correspondingly adjust structure
  • hints night observation
  • hints solar observation
  • short interview for S1 and S2
  • e-mail templates
  • OST manual → obsolete because of Wiki? (rh)
• clean up organisation in the svn → partially done (rh)
• add HIP and SAO numbers to the list of binary stars in the svn, because for example the CGE-Pro understands only SAO
• fill backup with observational data for students in svn
• Stocktaking of the OST and lab room 2.009 → Inventory
• fill darkarchive continuously with new data
• acquire a raspberry pi as weather cam and for weather information?
• finish bashscript for slot remindation
• create a bashscript to tweet the current weather
• update the telefone list in the dome
• add pictures to gallery
• update QR-Code/install NFC-tag for our gallery on the stairs to the telescope
• create a better/more modern first page for our server

• standardize expectation horizons
• extend exspectation horizons for interviews (only for internal use)
• N1-instructions: replace spectrum examples
• improve N1
  • optimise DADOS analysis → maybe not necessary anymore because DADOS is used with the ST-8 now which is more insensitive unempfindlicher with respect to Fringes → apparently this is only partially correct
  • optimise BACHES analysis
    • improve normalization
    • implement different possibilities for flatfield corrections
      • Flatfielding via 1D-flatfield functions
    • enable read in of FITS files also in the pipeline
• Adjust n2_add_images.pro such that it can react to two different exposure times of the Images. (different darkframe directories)
• improve C7
  • fill archive data
  • construct analysis with nightfall
• develop alternative master observations
  • rotation velocity of Jupiter using BACHES
  • spectroscopic binaries Measurement of radial velocity(german link)?
• possible additional bachelor observations:
  • develop bachelor observation regarding a new telescope alignment
  • develop bachelor observation regarding the rotational velocity of Jupiter
  • develop bachelor observation regarding the calibration lamp for the spectrographs konzipieren → is this still useful since we have BACHES?
  • additional solar observation from C2 covering solar activity
    • C2 should be enhanced → If activities on the sun are visible then observe, if not use archive data
    • Do we have a formula for the intensity profile of a sun spot? – account for influence of the filter

• create a new version of the The laboratory course computer for your home (a12 to go) and then update the wiki page (with the whole VirtualBox-thing etc.)

• set up aJabber server on polaris for fast communication? →Openfire Jabber Server
  • document the new Jabber server
• memory script can't work anymore due to the forwarding of the individual slot pages

• two wodden chairs for the dome: The metal chairs are so terribly cold in winter → < 50 Euro
• All-Sky Kamera 340 from SBIG: source: Baader Planetarium → 2240 Euro klick
• Seeing-Monitor KAF-0402ME: source: Baader Planetarium → 2910 Euro klick
• weather station → Which one?
  • or Raspberry Pi Starter Kit (~70€) with AirPi (~80€) (for example) with IR-camera (~30€) and fish-eye (e.g. this Case) (30€) (here), 26 Pin GPIO Male to Female Ribbon Cable (~4€)
  • buyable for 200-250€, has to be set up, but it shouldn”t be a big deal. With that we would have an All-Sky-camera, Seeing-Monitor and an ultra-mega-super-duper weather station in one thing!

• memory update für a12
  • 1TB for the Backup

• P Cygni (as soon as possible with the BACHES - V = 4.8 mag)
• observe M4 or a similar globular cluster with the BACHES – just put the slit on the central region for Martin
• M97 (Owl nebula)
• Mars, Saturn, Jupiter, Venus with the DSLR
• NGC6939, NGC7789 with the STF8300M to compare with the ST-8 (N2)

• Algol, RZ Cas, V1016 Ori, U Sge and U Cep for the C7 data archive
