Jerry Yesavage was kind enough to share some valuable processing tips with me. I applied these tips to my dataset and managed to tease out just a bit more detail using some revised GHS stretches and HDRMT. I suspect there's just not much detail to be had owing to the limitations of my 8" aperture. This target really screams for a big scope but all things considered, the EdgeHD 8 does surprising good with challenging targets.
I did wind up deleting the original version as for some reason, the mouse over to the cropped version stopped working.
@Jerry Yesavage has been imaging some very interesting planetary nebula recently. When he published his Astrobin debut of Planetary Nebula G156.4+01.1, I thought I would be taking a pass on this object. I reneged on the saner approach because I enjoy imaging PN and this target happened to fall within the prime area of my backyard view. More importantly, I was fascinated by Jerry's write-up for this object. I am providing the link to Jerry's image and write-up for reference:
https://www.astrobin.com/9utl03/B/Jerry indicated the presence of some weak Oiii signal in the center of the object. I'm outmatched by his EdgeHD 11 but I thought my darker Arizona skies might compensate a bit for pursuing the elusive Oiii signal. Overall, this object is extremely dim and challenging to image but I was able to detect a distinct presence of Oiii after some long exposures and aggressive stretching as evidenced here:
I believe this is the second image of this PN posted to Astrobin. The object is interesting but is probably better suited to a lot more aperture than my trusty EdgeHD 8.
