NGC 891, an edge on galaxy in Andromeda

Broadband imaging is already tricky in the suburbs but I perhaps didn’t help myself by trying to image this lovely galaxy with an almost full moon chasing it across the sky and haze. But still, for 4 hrs of data this RGBHa image is okay. The star field is aggressively clipped to remove the psychedelic rainbow mottling which I think is just pure moonlight.

For the rest of January, I had two more nights where I attempted to capture this target, luckily no moon glow just LP. So here is take 2, this time about 1 hr each of RGB and only 40mins of Ha. But you can easily see the improvement from by the better seeing and lack of moon – more fine details in the galaxy and lots of smaller galaxies sprinkled throughout the image.
