Here's an image I took of Neptune and Triton (??) a while ago. Not much in the way of detail recorded for either, both come up as fuzzy blue blobs, but still interesting in their own way.

 

[edit] Based on some recent feedback, seems that it's not actually Triton, more likely to be a stray star in the background that wasn't in the SkySafari database. Sorry about that blush.gif .

 

Celestron Evolution 6" SCT, Canon 700D, Celestron 2x Barlow, Baader Neodynium SkyGlow filter, ISO 1600, shutter speed 25 sec, with a little processing and image reduced to 0.2 [edit] 0.5x actual in Photoshop Elements.

That's not Triton - it never gets further than 16" from Neptune, or something like 7 Neptune diameters.

Hi happylimpet, thanks for that, looks like I may have got a bit over-excited with that Triton call.

 

Below is what I was expecting to see from SkySafari Plus, looked very close to what I got confused1.gif so I made the call. It may well have been a star in the background that wasn't in my SkySafari database.

 

I'll update the original post with an edit.

 

Thanks,

 

Andrew

Sorry to be a killjoy. Have you tried stretching the contrast a lot to see if its there in the background?

No worries, all good. Prefer to be right any day. I've had a quick stretch of the data, but it's difficult to see anything except noise at the moment smile.gif .

 

In retrospect, it's probably also too bright compared to Neptune, even with a 25 sec exposure. I'd only had the scope for about 2 months prior to taking this, so put this one down to inexperience and over-enthusiasm.

 

Thanks again,

 

Andrew

Anyway, regardless of that, its still cool to see Neptune as a small blue disk with a star for comparison.
