Monochrome clouds around Sadr

[tomato]

Here are a couple of images captured last night of the region around Sadr. The widefield view is 14x10 mins of 7nm Ha with the SY135 lens and Moravian G2-8300 CCD, the closer view is 56x3 mins with the RASA8/QHY268c/NBZ combination. Colour was not really an option with the moon so bright so I converted the monotone OSC image to B&W. 

My knack for bad framing continues, I notice I have managed to chop through the Crescent Nebula on the Samyang framing. In B&W these hydrogen clouds remind me of the watery ones we have to contend with on Earth.

Does anybody have any information on the filament structure that is visible in the lower left of the RASA image, it doesn't appear to be visible anywhere else in the FOV?

Gotta love Ha black and white images.  (^8

I noticed the same filamentary structure in an image I took and noted it looked pretty remarkable but didn’t find out any more about it.

Great Ha-images Steve! I have no idea about the filamets I am afraid, but they are enigmatic. And who cares about a cut off Crescent, there are enough images of that one.

Did a quick Google and found this:

The visual filamentary structures may be in the same region as described in the paper, I’m struggling to interpret the accompanying illustration, but it looks like a plausible explanation.

Great image - love the black and white.  I appear to have just managed to capture some of the same filaments in this image.  I am planning to add a lot more data to it so will see if they can be further elucidated...
