North is left, mirrored. 0.33 arcsec/pixel (16' by 11') Total exposure time: 457 * 30 seconds = 3.8 hours. Exposure used in stack: 187 * 30 seconds = 1.5 hours. Telescope: C9.25 (230mm aperture, f/10, fl=2300mm) Camera: IMX533 (16 mm diagonal, square, OSC) Processing: (no software sharpening used) Callibration stacking (average w/ rejection) White balance and blackground subtraction Asinh stretch Light denoising Tone curve Crop There's not too much to say about this: it's barred spriral galaxy with uneven arms. Because of it's fairly low surface brightness (as galaxies go), the image uses data collected across nights. However, it's still not very much because of the vanishingly small amount of darkness this time of year, and because I forgot the dew shield on during the second night. However, there is a nearby galaxy cluster at 12h15m37s +69°32'30": I don't think this has any names or catalog designations. Hubble hasn't imaged it, so the best references avalable are ground-based sky…
