I haven't published any pictures for quite some time. This is primarily down to spending most of my time alternating between asteroid and supernova surveys. However while rooting through some data I remembered this which I had captured but not finished.

NGC2841 is a lovely tighly wound spiral in Ursa Major. It has an integrated magnitude of +9.2. It's 42 million light years

Here's the pic (be sure to click on the image for the full size)

The image itself contains 3hours of luminance combined with 90mins each of RGB. The colour was then G2V calibrated.

Equipment was C14 @ f/5.0 (Optec Nextgen focal reducer), AP1200, SBIG ST8 and CFW9 filter wheel with Astronomik LRGB filters.

Hope you like it.

Exquisite detail, the "knots" in the spiral arms are beautifully defined. Thanks for posting!
