If you read the stats, Neptune was 241.3 light minutes away at the time of this photograph. That's just over 4 light hours away. For fun here's a size comparison via the wikipedia page.
At that distance Neptune is only 2.4 arc minutes in size and the top image that I took is fairly close to what you might see in a moderate telescope at medium magnification.
After some wide-field CCD shots, I put in my high-res planetary camera and took some LRGB as well as Infra-Red (742nm) shots. Here's the aesthetically pleasing composite consisting of all 5 filters that also includes a Triton.
Finally for the detail oriented here's the full layout, including the sub channels used in derotation.
Also here's the alignment reference from the Neptune Ephemeris Generator (http://new-pds-rings-2.seti.org/tools/ephem2_nep.html)
Thanks for reading and please do some well wishes for more clear skies for me, they've been far and few between.
