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
