Neptune and Triton - August 17 new

This is Neptune and Triton in IR. I believe the brightening at Neptune's south polar region is real. I was also able to capture that in red, but not as distinctly. Green and blue were featureless.

Hi Peter, very interesting. The brightening is coherent with the orientation of the south pole (this is missing on your image, you can use the PDS Node Ring simulation)

Pete, awesome Neptune capture! It't the first detail I've ever seen. Congradulations and it looks like I need to add the IR742 filter to my ever growing astro wishlist... Thanks for posting

Regards,
Steve

I think a Baader 685 IR filter would be better for the job. I have one on order and it should be here tomorrow! I think a 742IR filter is better for objects with a higher surface brightness. I just got lucky with having a very steady and transparent sky at the time.

Christophe,

Thank you for the link to this simulation. I resized my image and superimposed on the simulation. It matches perfectly!

Superb imaging Pete! Very solid result--- I don't recall anyone getting Neptune nearly so well with an aperture under 20" or so...

... now go get those rings!

This is a excellent result, really. As a last test, you should try again with the camera in another position; but it smells really good !

Hi Pete,

Great capture! Did you see Marc Delcroix's Neptune images over on ALPO-Japan? All were obtained using a 1-meter telescope and look almost like yours. Damian's September 25, 2010 Neptune image listed there is also worth checking out. You're definitely in the major leagues with those guys. Capturing details in Neptune's clouds with 14" telescopes, who would have thought that possible twenty years ago? I find it remarkable today, congratulations!

Clear Skies, Dan
