Sh2-224 & Sh2-223

In this image, there is two supernova remnants!
Both are extremely faint. Exposure time was 15x1200s = 5 hours,
and in final image there was very litle information.
I wanted to try this difficult targe to see can it be imaged from the city center and
with QHY8 color camera. After tweaking the data about an hour, I was able to say, it can.
Image here is a false color image, H-alpha = Red.
Imaging data:
Camera, QHY8 - Filters, Baader 7nm H-alpha
Optics, Tokina AT-X 300mm @ f2.8
Exposures, 15X 1200s H-alpha, flats and bias
Guiding, LX200 GPS 12" + PHD-guiding and Lodestar
