Hi Anthony

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



Hi Anthony,


Hi Ben,

I rather like diffraction spikes regardless of color.


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.



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



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


Ditto here ...



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



6888 is only a couple of degrees South. Are you going to try it?


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

It's a splendid but difficult object. Anyway your capture of B 343 is
just ominous.


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. :-)

Anthony.
