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").
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
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
SYS> gocat M33
The OSA can do it for you, too.
