Anthony Ayiomamitis

Dear Group,

With Cygnus slowly getting into good position for imaging, there is a
wide variety of goodies it provides for the interested observer and imager.

Given the plethora of Barnard dark nebulae it offers, I thought I would
try my hand with one of the largest such objects just north of the
bright star Sadr.

More specifically, I pursued B343 which lies within a couple of degrees
just north of Sadr. For an image based on four hours total exposure, I
kindly direct you to
http://www.perseus.gr/Astro-DSO-Nebulae-Dark-B343.htm . This is my first
attempt at a dark nebula and I would welcome all feedback. I have
checked around and cannot find any reference images for comparison B343
.... if someone has pursued this particular object, I would love to see
your results.

Clear skies!

Anthony.

Nice. Here is one I found on google images:

I found this interesting image of DWB41 & B343 with poorer resolution than
your excellent image, Anthony.

Thanks George! It confirms my suspicion that the result needs some H-a
data to improve the luminance portion.

It certainly does and I thank you!

Thanks Sam! The fellow strictly used h-alpha which confirms my
suspicion about needing the same. In fact I have the same h-alpha filter
he used and which I will put into use (probably this evening).

To the rescue once again. :-)

Hi Anthony

I'm not a fan of diffraction spikes, especially when they turn red

However, it is a very, very nice image with great subtle detail. I must
have looked at this area and overlooked this DN many times visually

Looking forward to more. I find that looking for DN brings out the detail
in the surrounding area alot more.

Regards
Paul

Hi Anthony,
I rather like diffraction spikes regardless of color.

I have viewed it several times. It stands out right easily
against
IC 1318 in the background.

6888 is only a couple of degrees South. Are you going to try it?
It's a splendid but difficult object. Anyway your capture of B 343 is
just ominous.

Great looking image and those dark nebula take plenty of exposure time
too. The web address I provide here is of the Ha region with Sadr in
the lower right hand corner. This was a total of 90 minutes in Ha and
45 minutes total in RGB with a FSQ106n and ST-2000 camera at Palomar
Mountain last year. I plan to return this year with a ST10XME and re-
shot that area for more detail and a little large field of view.

It is one of those things which you either like or dislike. There seems
to be little middle ground. I also do like them as well.

In fact I took some test exposures about ten days ago in h-alpha ... WOW!

I expect a very nice result with the Crescent Nebula. I suspect I will
pursue it aggressively a few days after full moon (this lunation) since
it has been a "to-do" item for some time (similar to the Bubble Nebula
in Cas which will have to wait a bit) and I have a good idea of my
exposure times for both h-alpha and RGB.

Back at it again this evening for another Barnard dark nebula. :-)

In fact I took some test exposures about ten days ago in h-alpha ... WOW!

I expect a very nice result with the Crescent Nebula. I suspect I will
pursue it aggressively a few days after full moon (this lunation) since
it has been a "to-do" item for some time (similar to the Bubble Nebula
in Cas which will have to wait a bit) and I have a good idea of my
exposure times for both h-alpha and RGB.

Back at it again this evening for another Barnard dark nebula. :-)

That's it! When I retire it will be in Greece! On the western slopes
of Dirfys, Evia, I think.

Themi,

There will be the annual national star party on Dirfy next month ... I
think it is around July 20-22/2007.
