After my mixed results with recent galaxy imaging, I thought of trying something new to me. Kind of, because this is my second planetary nebula, the first one being the Helix done a few weeks ago.
This time limited integration with just 9 hours in total. I suppose a larger aperture is needed to split the central double, but other than that I think the image turned out alright.
Looking pretty good Suavi. This was the first planetary that I attempted imaging a few years ago but my result wasn't anywhere near this good
Thank you Colin. I couldn't find your attempt at it on Astrobin. It's a different target to what I'm used to imaging so it has been fun trying to capture it with my 105.

Thank you Steve. I tried other channels (Sulphur and Nitrogen) and there was hardly any signal, but if I get a chance I may try adding a bit more data.

Very nice structure shown, including the faint wispy bits of stuff around 3 or 4 o'clock.
Thank you Mike and Trish. The separation is only 3.8", which equates to about 3 pixels with my camera/telescope. perhaps shorter than 15-minute exposures would help in splitting them a bit more?

Thank you Geoff. I'm starting to gradually understand the limitations of a small aperture.
Lovely shot Suavi, great colour and excellent res for a small scope

Thank you Mike, Rodney and Paul.
Out of curiosity I picked two tightest single 15-minute subs, one in Ha and one in OIII. I think I can call it a split...
Not too bad for a 3.8" separation with only 1.18"pp and 105 mm aperture...
Before I will seriously consider a larger aperture, I may need to look at improving guiding even further and capturing more but shorter subs and then selecting only those that have the tightest stars.
Hard to do that with 105mm, but trying nonetheless. I think I am starting to develop an appreciation of fine detail in DSO images...

Thank you Lee. I was curious about this little gem myself.

Thank you Rick. Although there was not much SII signal that I could detect, I suspect there should be some around the outer edge where the shell pushes against the interstellar medium, so I may try capturing SII tonight.
After seeing this image I thought of trying collecting SII last night.
Sadly, 6.5hours worth of 15-minute subs had hardly any SII signal in it, nontheless I combined whatever little SII I had with Ha and OIII and the result is here: https://www.astrobin.com/full/367738/0/
