Don't know too much about this Supernova Remnant, other than I haven't seen many images of it besides IR and X-Ray. I thought it would be cool to see if I could capture it. This is in the constellation Cas and is very close to the Heart Nebula (IC 1805) and the Fish Head Nebula (IC 1795). In fact, if you look in the upper right-hand corner, you can see the outline of the Fish Head.
With the weather here in VT, I started this project in November 2023 and didn't take my last image until January 2, 2023! All that, and I only wound up with about 9.5 hours on the target. To top things off, I must have rotated my camera prior to my RGB stars session, so I couldn't even use those beautiful RGB stars without having to crop a lot of the SNR out! I'm still hoping to get a bit more time on it, though, but I was growing a little weary of the same target.

Beautiful image Greg... I don't know anything about it but it seems a fine AP target. Like the colors and the contrast of the object. Very cool!

@terri Thanks, Terri! I was anxious to see what I had after almost two months! More detail in there, I suspect, with additional time.

I finally was able to get my RGB stars for this supernova remnant last night, so I updated the image. More natural stars, I think. I added the capture date and exposure time for these RGB stars to the list below.
I also eliminated the extra brightness I added to the image initially, so the colors appear more saturated.
