I tried again tonight. I think I got it, but I'm not sure. This is as high as the magnification will go with my DSLR. If that is Neptune, that little dot right next to it could be Triton?
Well it seems to have a disc versus other pinpoint lights. What is your effective focal length here?

However, CdC stars do not appear to match quite as well (?)

Maybe a longer exposure would bring it out.

I can't tell about the field, but the size of the disk and relative distance/brightness for Triton match my visual impressions in recent nights.

This is how it looks in Stellarium for my location at the same time. Seems to match.

Looked at Neptune Friday and Saturday night from Cathedral Gorge State Park in east central Nevada. It was a tiny bluish-gray disk, with of course, no details. Was a bit too blurry due to mediocre seeing at 102X. Tried 229X but didn't do it any favors. Never tried my aperture mask because I could tell it wouldn't make any difference. Still too low on the horizon both times I looked. It was still nice to revisit an old friend. Also seen Pluto for the first confirmed time. I found and tracked the dot over Friday and Saturday night. Nothing to write home about except saying I saw the "dot!"

@chrysalisI think if your image were rotated about 45 degrees to the right it would match mine.

Edit: ok, maybe not. at first it looked as though it would.

Here's a slightly better version. I realize it's nothing fancy, but it's the first time I've ever seen Neptune with my own eyes, so for me it's pretty cool. I didn't intend to go down the astrophotography path, but it is kind of fun.

I remember the first time I saw Neptune and Uranus through the eyepiece, I was floored by a sense of immensity. The Uranian light I was seeing had traveled 3 billion kilometers from the sun, bounced, and travelled another 3 billion kilometers to reach my retina. The Neptunian light had run an even longer round trip: 9 billion total kilometers.

This is a very good shot of Neptune! Triton would be inside the red oval drawn on this image.

Good job on that shot. I really had to enlarge the screen to pick up Triton.
