Here is protoplanetary Frosty Leo.
https://en.wikipedia.org/wiki/Frosty_Leo_Nebula
Visually in my 18" , is a small faint round nebula with irregular border and amorphous structure. Distinctly non-stellar . Visible from my urban backyard, 2475with glare from streetlights.
In infrared, very bright. Two flattened ellipses separated by a dark lane, and a tenuous outer envelope. The dust lane runs almost exactly east-west
Attached infrared image taken with handheld iPhone, cropped and increased contrast setting, The dust lane is not seen due to overexposed image (not much choice with iPhone ) Magnification approx 250x
Thanks
