Hi finished this the other day I thought this was a interesting area with the pair of interacting Galaxies in Eridanus. I had a very uneven background that I think is stray light from the laptop screen getting past the open truss of the telescope. I put the laptop in a box since then but now it over heats and shuts down in the middle of a imaging session.

Also, in the 10 o'clock position next to the bright star in your image, there is a red ring. Is that a planetary nebula or is it something left over from the image capture or processing ?
Thanks for the replies Trevor, Dr Paul , Geoff I would think the red ring is a reflection from the bright star not sure why it is only on the red filter?. Paul I had this Galaxy pair on a list I have that is well placed at the moment in the sky, when I started imaging it looked very interesting then I realized it was the same object that Martin Pugh had done a great image with a little time ago.

Thanks for the reply Humayan, the seeing from my site is usually poor and the heat in the observatory was high, making conditions less than ideal but overall I am pleased with the image.

What an interesting and beautiful image! It is in my list for 2012.
The curiosity bug: you are binning 2x2 and your scale is about 1 arc sec per pixel. Have you tried to apply drizzle to your images while stacking even though you are not oversampling?
Thanks for the replies John and Peter never herd of the Woomera galaxy but the name suits. Enrique I don't know much about Drizzle I just doubled the image size for each colour layer before stacking. With my average seeing and tracking 3x3 binning might have returned the same result in less time.
Clear Skies Ken.
Thanks for the encouragement Colin I usually get out every clear night.Rich get that colour data while you can, and Marc you have a frog fetish
