The constellation Musca is a southern constellation bordering Centaurus and Circinus. The surrounding neighborhood is home to many popular DSOs and asterisms, but Musca itself contains many very interesting never before imaged deep-sky objects. This field features three newly discovered PN candidates, all three being Oiii dominant objects. Fal5 being the target of interesting for this image.  I encountered Fal5 in the process of capturing my image of the Theta Muscae SNR, which is a very insane structure! My 135mm survey images showed some hits of a circular object in the periphery, which I initially thought to be reflection nebula before doing some more digging. What I ended up finding was an object of peculiar similarity to my first discovery, Fal object 1. [img]https://cdn.astrobin.com/ckeditor-files/9294/2023/55957065-30a2-427f-ab1c-70ff4f0a20c7.gif[/img]  Comparing this nebula to Fal obj 1, there appears to be some analogous structures. Particularly a small inner shell bubble surrounded by a greater envelope with a bright leading edge, full of sharp ridged structures:  [img]https://cdn.astrobin.com/ckeditor-files/9294/2023/cc4331d9-f6bb-4664-9310-81b00756dfb6.jpg[/img] as for an explanation of this similar morphology, your guess is as good as mine!  While imaging this nebula, two more turned up after doing a lot of exposure, Fal4 and Fal6 Fal4: [img]https://cdn.astrobin.com/ckeditor-files/9294/2023/aa38f90b-5008-44c5-b60b-3963cef6ea03.png[/img] Fal6: [size=50][img]https://cdn.astrobin.com/ckeditor-files/9294/2023/744f57a9-16cb-4c19-beb7-94bb60077c4a.jpg[/img][/size] Image capture was done this last June from Hakos!
