Question about field of view

[Rocket Pooch]

Hi,

Got me SAC8 and a new short tube refractor, I've put the details into K3CCD and its given me a field of view of (arc seconds I think): -

44.00' x 33.00'

So what does that mean then?

All I wanted was something more wide field, my Europa gives: -

19.56' x 14.67'

The meade gives : -

11.84' x 8.36'

What would this mean say for M42, how wide is that?????

M42 is 80' x 60' but thats the full object you can always try for the central portion.

The measurements given are in arc minutes
  An arcminute is a unit for measuring angles between
objects in the sky.  It's a small unit:  the Moon and Sun,
for example,  are about 30 arcminutes across,  and the
distance from the horizon to the point straight overhead
(the zenith) is 5,400 arcminutes.  A single quote mark,
or ',  is usually used to indicate arcminutes:  i.e.,
"The Moon is 30' across."  There are 60 arcminutes to a
degree.

Thanks for that, I need to know this to get a perspective when imaging.

Could you call me sometime, I need to ask you a question about imaging and a few other things.

Thanks
