Object List
If you have many objects, then create a simple
target list before your observing run. It can be fed into the telescope
control computer and saves you from typing coordinates late at night.
- Write your object list in the format:
name ra(hh mm ss.ss) dec(dd mm ss.ss) equinox
where name can have up to 20 characters and equinox specifies the epoch of the source coordinates ("B1950", "J2000" or "APPARENT").
Example:
M33 01 33 51.02 30 39 36.70 J2000
NGC157 00 32 14.40 -08 40 20.00 B1950
GJ398.2 10 39 36.74 +43 06 09.25 J2000
- The list file must have extension .cat (e.g. mylist.cat).
- Once you are at the telescope, copy mylist.cat into the directory /wht/cat/
- Tell the observing support assistant (OSA) to include mylist.cat as an user catalogue into the TCS
- Now
you can move the telescope to each object loaded into the TCS, by
typing this command into the window that also accepts all the other
observing commands.
SYS> gocat M33
The OSA can do it for you, too.
