Abell 12

Hello Group,
Checked out Abell 12 through the telescope with the naked eye
under average seeing conditions and ended up frustrated not
knowing if I was seeing the object or not due to it being so close
to the 4th magnitude star Mu Orionis.
To slay my frustration I decided to image the star in the hopes
that I would have the planetary nebula in the same field of view.
Using my new ASI224 camera and the same telescope (7 inch Mak.)
and 140x15 sec. exposures with a gain of 210 and a couple of darks
I watched in awe as Sharpcap stacked image after image to produce
the picture below. A little tweaking with the histogram really made
Abell 12 stand out. Sharpcap and the ASI camera truely work wonders.

:)

Hi,

nice image - it would be so easy to dismiss the planetary nebula there as just some reflection of light from the bright star inside the telescope, but you clearly found your target :)

cheers,

Robin

Hi Robin,
Yes, that's what I thought it may have been
after the first few images came through, but
as the image became clearer (more stacks) all
my trepidation vanished, soon being replaced
by a smile of relief and satisfaction.
Thanks for the great software which makes it
so much easier to image faint objects such as
this.
