Finding Heart Nebula
The Heart Nebula lies to the left hand side and slightly south of the big “W” that is the constellation of Cassiopeia. Imaging *UPDATE* Now that I have a reducer/flattener I decided to have another go at the Heart Nebula due to its size. What the reducer/flattener does is to 1) reduce the focal length, which in turn gives me a larger field of view, 2) It makes the telescope “faster”, this means that I can shorten my exposure times and or amount of exposures taken and 3) It flattens the image. This means that I do not get elongated stars around the edge of the image. As you can see by comparing the image above to the one below with the reducer/flattener, the entire Nebula is in the image as opposed to only a little bit of it in the image below, also the stars are round to the edges. Also, this image was taken during a 99% Moon and it looked like daylight but with some heavy editing I am happy with the result. *Original Post* Once again I didn’t realise quite how big this Nebula is and low & behold, it was too large to fit the whole nebula in to the field of view. Either way, I am happy with how this image has come out. I will be spending some time on this Nebula and i will image the whole thing and “stitch” them together to show the complete Nebula. Watch This Space.

*UPDATE*
Now
that
I
have
a
reducer/flattener
I
decided
to
have
another
go
at
the
Heart
Nebula
due
to
its
size.
What
the
reducer/flattener
does
is
to
1)
reduce
the
focal
length,
which
in
turn
gives
me
a
larger
field
of
view,
2)
It
makes
the
telescope
“faster”,
this
means
that
I
can
shorten
my
exposure
times
and
or
amount
of
exposures
taken
and
3)
It
flattens
the
image.
This
means
that
I
do
not
get
elongated
stars
around the edge of the image.
As
you
can
see
by
comparing
the
image
above
to
the
one
below
with
the
reducer/flattener,
the
entire
Nebula
is
in
the
image
as
opposed
to
only
a
little
bit
of
it
in
the
image
below,
also
the
stars
are
round
to
the
edges.
Also,
this
image
was
taken
during
a
99%
Moon
and
it
looked
like
daylight
but
with
some
heavy editing I am happy with the result.
*Original Post*
Once
again
I
didn’t
realise
quite
how
big
this
Nebula
is
and
low
&
behold,
it
was
too
large
to
fit
the
whole
nebula
in
to
the
field
of
view.
Either
way,
I
am
happy
with
how
this
image
has
come
out.
I
will
be
spending
some
time
on
this
Nebula
and
i
will
image
the
whole
thing
and
“stitch”
them
together
to
show
the complete Nebula.
Watch This Space.
