Seimei Telescope User’s Manual
In this manual I explain the Seimei Telescope usage procedure step-by-step.
Procedure starts with manually setting-up the telescope mechanisms from the 3rd floor
of the building. Process in this manual should NOT be used blindly without supervision
by any means!
oTelescope Setup
1-) On the 3rdfloor of the building, just acrossthe entrance hall, check themechanism.
Correct shape is an “L” shape. If the mechanism is like this “_ı”, it must be switched to
the “L” shape.
You can easly understand if the position is correct by looking at the stickers at the
image below (they must be on same/close vertical line)

2
2-) There should be 15cm distance between the Kanji Seal and ZeroPoint as shown
below. From the stickers on the below image, you can understand if the position is
correct or not.
3-) The two arrows, the one on bottom showing the Home position, shown below must
be close to each other.

3
4-) On the control panels, power must be switch on as shown below. There are 3
units(2 bottom, 1 top). When switching on, the procedure should start from bottom-
right -> bottom-left -> top-left. When switching off, top-left panel is accessed from
computer so, we only need to close bottom panels manually.
5-) If the telescope is on, on the left-side computer we will have the screen below.

4
6-) On the middle computer, type “./telescopeM5 ” to start the screen shown below
where the user and location is : develop@localhost
7-) Take the controller shown below and push “All” -> “Down” to close the curtains.
There is an automatic panel to move the curtains on the Main computer as well.

5
8-) Go down to the 1st floor. Type cont380 on the left-side computer.
9-) Upon typing cont380, a new screen will appear. You will be asked to enter the
proposal ID. Here the “K” letter is for Kyoto. Choose the Proposal ID and type the
observers name and click “Go ahead”.

6
10-) Zero Point must be set for all (position of telescope and mirrors). The process is
now automatic. Under the Dome control, click Setup and choose the zeropoint searchs
and click “Start”.

7
11-) On the top middle screen, we have the Feedback. Simply click “Start” under the
Feedback Control section. As long as we don’t see any errors on the right side of the
screen, everything is okay. Difference around 500 is okay.
17-) On the second bottom left screen, we need to open the KOOLS software. For that
we need to type “ ./KOOLS_obs_GUI.py”. we use the terminal with
“messia@kools2017” name. NOT “seimei@SeimeiConsole1”.

8
oCalibration Images
18-) Upon entering the script, a new screen will appear. Here we first click “Start” on
top of the screen and then “Initialize all motors”.

9
19-) Choose VPH-blue from the “Filter and Grism” option but DO NOT start exposure
sequence yet.
20-) We go back to the big screen on the left side and from the Main Controller panel
we click “Flat”
21-) Under Main Controller panel, on the right side of the screen, from “Instrument
Select”, we choose “Flat&Comparison” and click “Change”.
22-) Under Instrument Select, from the “Lamp Control”, Click “Flat-lamp” & “ON”

10
23-) Back to the second left bottom screen and write the Exposure time as a value
between 15 to 20 seconds. Click “Start Exposure Sequence”. Wait until it finishes. We
will only take 1 exposure first! Then if everything is okay, 4 more exposures.
24-) Open the created .fits file with ds9.

11
25-) Check if there is any oversaturation. We can check the Value across the image
quickly. Any value below 65000 is good. Over 65000 means oversaturation. Therefore,
image can’t be used and taken again.
26-) If everything is okay, take 4 more exposures with 20 seconds exposure time and
check all for oversaturation as well.
27-) Back to the big screen on the left. From Lamp Control section click “OFF” for Flat-
Lamp.
28-) Again from the same Lamp Control Section, choose Ne-Lamp and click “ON”.

12
29-) Go back to the screen with KOOLS and choose Exposure time = 1 second and
Multiple exposure = 1. Then click Start exposure sequence. The .fits file should be like
the image shown below.
30-) Back to the big screen on the left. From Lamp Control section click “OFF” for Ne.
31-) Again from the same Lamp Control Section, choose Hg-Lamp and click “ON”.
32-) Go back to the screen with KOOLS and choose Exposure time = 5 second and
Multiple exposure = 1. Then click Start exposure sequence. The .fits file should be ike
the image shown below.
We can also use the Scale Parameters from ds9 to quickly check for oversaturation.

13
33-) Back to the big screen on the left. From Lamp Control section click “OFF” for Hg.
37-) When obtaining comparison images finish and the lamps are closed, it is time to
get the BIAS images. For that, from KOOLS screen choose VPH-blue and set the
Exposure time to 0(zero) seconds and Multiple exposure to 1. Repeat it for 4-5 times.
! NO Dark files are needed because the CCD temperature is really low.
38-) After taking the BIAS images finish, go back to the big screen and click Home to
set the telescope to home position.
oObservations
39-) From Dome Control, open the Dome and make Rotation Auto and Shutter OPEN
40-) Connect the ZWO Camera from the menu below. Choose the camera, MONO 8
and 5496 x 3672 and click “Connect”

14
41-) Make the Rotator “in” and Rotator Tracking mode “Star”. From the “Instrument
Select” under the “Main Controller” section choose “Shack-Hartmann” and click
“Change”. Enter the values before and turn Power to “ON” and Start the M1 Alignment.
Check the feedback for difference (~500 is acceptable).
42-) From the “Instrument Select” under the “Main Controller” section choose “ZWO-
Cam” and click “Change”.
43-) From the “Main Controller” section under “Useful Interfaces” click the Catalog and
open the .dat file with a bright object (sh3.dat etc.) and click “Go Tracking”.

15
44-) From the “Main Controller” section under “Useful Interfaces” click the “Control Pad”
and a new window will open where you can move the aperture to the target star. Here
if the aperture is not on, from “Markers and Guides” open the aperture. If you can’t see
the star, try increasing the “Gain” or “Exposure time”.
If the star is not focused, from the “Main Controller” page try to adjust the number.

16
45-) Now go back to the catalog you have opened. Change itto the observation catalog
and your targets (with sky and near object) will appear.
1. Choose the near object first! (For example, n2019qtk) Since our actual target is
too faint, we will calibrate our focus with anearby bright object. After you choose
the near object click”Go Tracking”.
2. Make sure your ZWO-Cam is on. Again, get the object to the middle of the
aperture with the control pad.
3. Then go back to the catalog screen and choose your actual target (2019qtk)
and click “Go Tracking”.
4. From the “Instrument Select” choose “KOOLS-IFU” and click “Change”.
! Before you start the observations, check all the conditions; Lamps are closed, Dome
is open, shutter is open, your KOOLS-IFU camera is selected, target is well focused,
the feedback is within acceptable range and there is no error message anywhere.
5. From the MESSIA, with VPH-Blue, write the exposure time as 600 seconds and
multiple exposure as 1. Then click “Start exposure sequence”. You can open
the sound if you want to hear when the observations finished.
6. After taking one spectrum, go back to the catalog screen and choose the near
object and click “Go Tracking” and switch your camera to ZWO-Cam and again,
get the star in the middle of aperture. Then go back to catalog, choose your
target and start the sequence again. Repeat this until you have the desired
number of spectrums.
7. After finishing taking the enough number of spectra, go back to catalog menu
and choose the “sky”, we will be taking spectrum of the sky now. On the MESSIA
change the exposure time to 300 seconds and multiple exposures to 2 and start
the observation sequence.

17
! From is the process for how to close the system:
46-) From the main screen, Upper Light = ON and from the Initialization and
Termination window, click “END”.
On the new screen Choose All except “telescopeM5 Quit” and click “Start”.

18
47-) From the KOOLS screen, click MESSIA = STOP and close the screen.
48-) Go to the Feedback screen and click Feedback = STOP
49-) Go to the control panels on the 3rd floor and push “POWER OFF” button starting
from bottom right and bottom left panel.
50-) From the controller open the curtains by pressing “ALL” -> ”UP”
NOTES:
*If the messia login is not open, write the code below to open it. Password is Kyoto3.8m
*Taking lamp images after the observations (1 before the observation, 1 after
observation) will improve the calibration quality.
*If there is rain outside, rain detectors will show it like below
