This almost edge on galaxy is a spiral galaxy. I took this image under very clear conditions with no moonlight and stars visible down to magnitude 5.
I was using my 10 inch, f/4.8 reflector, a Vixen Atlux mount, PHD auto-guiding and an Atik 383 L mono CCD camera.
I captured 5 minute sub-frames with matching dark-frames and used flat-fields to reduce the effect of vignetting in the final image.
The camera was set to x1 bin mode for the luminance data using an IDAS filter. For the colour data, the camera was set to x2 bin mode.
The total exposure times were 60 minutes using an IDAS filter, 5 minutes using an OIII filter, 5 minutes using an H-alpha filter and 5 minutes using a blue filter.
