NGC2403 is a very low surface brightness galaxy, and is an outlying member of the M81 group. My skies will never show the true glory of this galaxy, which extends beyond the frame here.

A touch of deconvolution has sharpened things up a little - as some optical gremlins and naff seeing had conspired to make things a tad blurry.

Total integration time is a little over 4 hours, spread over two evenings.

Here is last years image of NGC2403 I doubt there will be enough clear nights to get extra colour this year, so one cloudy night soon I might try combining the two.

Captured in ArtemisCapture, calibrated in ImagetoolsCa, DDP and deconvolution in maxim, thuggery in photoshop.The grey bar at the top is a processing artifact, and didn't want to go away. Git.

This image was autoguided using my 400mm focal length refractor and my black and white SC1 webcam.
