Description

This is part of SH2-224, a supernova remnant in Auriga. The whole object about twice as large as the section shown here. What I've learned is that (1) I need to learn to do mosaics, and (2) I need to look at my instrument/sensor response and figure out the relative sensitivity of my sensor at O-iii wavelengths vs Ha wavelengths. I feel like the blue should be a little stronger, and am wondering if the sensor is just less responsive in that part of the spectrum and needs relatively longer exposures.
