Another great looking image Yue.  It looks like you might have a little room on the black point (can lower it slightly) to gain a little more contrast.  This was the last target I shot before the Summer clouds moved-in.

Another nice 6992 Network. Are you imaging through a diagonal?

Thanks guys!
Jason,
No I didn't use diagonal. I don't use diagonal at all.  :-)
For this one I also didn't use flattener, so the field curvature is obvious. Even I cropped you still can see that at corners.

Eric,
I'll try your suggestion with PhotoShop then - my PixInsight has passed the evaluation period, and I'm still not convinced to buy it. Somehow I feel it was not so easy to use.

Yeah, and the clouds seem to never stop rolling!

I only wondered because the object is inverted from typical presentation.

I see.
Actually, the same inverted view in all my 3 images here, and now I remember I've noticed that the image is changed when opens in FITS Liberator.  Interesting! :-)

Ok, in FITS Liberator there is a checkbox as "Flip Image" the default is checked. That's why my image has an inverted view.
I guess the application assumes the use of a reflector, and I didn't notice that checkbox until now.
