My first image of Neptune, 10" dob + DMK
Hi all.
Here's my first ever image of Neptune, captured on Friday night 15/09/2006, in good seeing and good transparency. The left hand image is at captured resolution, using the 3x barlow with my 10" dob, EQ platform and DMK21AF04. The right hand image is resampled 150% in registax. I captured Luminance at 1/8s (7.5fps), and stacked 200 frames, and the RGB channels were captured at 1/4s (4fps) and 180 frames of each were stacked. I captured for 1 minute on each channel. The RGB channels were aligned and combined in AstraImage, with Luminance layered in Photoshop. Levels were adjusted for brightness. I'm quite pleased with my first ever image of the (now) farthest planet  Ideally I need to use 1/2s exposures or longer (more like 1s) to be able to use the 5x powermate, but my tracking platform is not accurate enough for long exposures. Maybe in the future.Thanks for looking.

Not bad at all.

This is great and really inspiring. I have always passed on imaging the more distant planets -- but I will pass no more.
Mike, you set the bar really high -- great work!

Thanks for your comments guys, it means a lot.
I'm happy to have got this image of Neptune, because I probably won't try again until i've got a more accurate mount. It really needs a longer exposure and I can't do that with my setup.
