Having been fascinated by the nebula PCG11 as an unexpected find in my image of the
Fighting Dragons of Ara I decided to point my 10" Meade at this intriguing little bubble that is being blown by a Wolf-RayetStar as I couldn't find any "typical" amateur astrophotography images of this target (but I may have just missed them). As I have the focal reducer on the 10" Meade, I am missing out on a bit of focal length, unfortunately PCG 11 and the planetary nebula Henize 2-169 are still relatively small in the fov (the image above is a cropped version). This image, with very limited processing, is only a stack of Ha 10hrs 20mins as the moon is now loud in the night sky. My plan is to add some LRGB to this, once the moon shrinks away, to produce a colour image of these two nebulae.
In the article that Marcel Drechsler kindly provided for me
https://academic.oup.com/mnras/article/360/4/1439/1079208 , the nebula PCG11 was described as having a 'lemon shape' due to 'blow outs' at each end and that the inner aspect of the nebula was scalloped. To me, this combination of the the lemon shape and inner scalloping looks exactly like the bones of a shark's open jaw, hence the name in the title - totally unofficial of course
Watch this space (pun intended
