G'day all,

 

Hella good seeing last night. So I just kept shooting. The edge persistence tanked at the end, so I stopped. But the output quality was in reality just starting to peak.

This was the best of the lot:

Super stuff BQ. What's Jupe's elevation for you there?

Thanks Kevin!

 

Here on the Tropic of Capricorn, it's way low this year. It only culminates at 81˚. This was 78-80˚. grin.gif

P.S. I've heard when Jupiter's this low, I might need something called an "ADC". Do you know what that is?

It's usually not even worth imaging when the target is less than 85 degrees in elevation.

 

Seriously, though, great images and I love the animation!

Truth be told, I'd take 50˚ over 85˚—at least under Red Centre skies. My best quality in my typical seeing is at 40-70˚.

Applying some learning (thanks to Tulloch, Borodog et al) to get maximum detail from the Mak 180, even in modest seeing:

Stereo pair @ 100% scale

 

I'm particularly enjoying the color contrast results up in the NPR…

 

Cheers!

Looking good, BQ! Tulloch and Borodog have both helped me a lot in my journey.

Thanks Tim! Among others in the AP forums, their technical curiosity has constantly made me reassess my workflows and improved my understanding of photonics and processing. It's made me a better photographer across the board—planetary, DSOs, and terrestrial. I am grateful for their queries, ponderments, and thoughtful feedback.

One of the coolest things about this stereo pair is that you can use your 3D sense to detect where the Mak 180 performance limit breaks down in this seeing. Wherever you perceive something like scintillation in the image is where there is registration error between the two frames. This is where the integrated wavefront error results in a "wiggle" in a sub-resolved detail in the image. It's particularly perceptible in the bands in the NTrZ. If you look at Hubble and probe mission images, you can see the tiny detail there that the Mak is picking up; it's just deposited in the image slightly differently in each frame. The scintillation pretty widespread at 100%, but zooming out to 50% it's isolated to just the NTrZ and inside the GRS.

Oooo…a slightly different color balance when upside down:

The colors feel a little like a Red Centre motif…

Well I'm flattered but I don't don't know what you think you've learned from me, given that I have no idea what I'm doing. Great images, though.

…I don't don't know what you think you've learned from me…

I know exactly what I learned—you put me onto an apples-to-apples with Hubble. Had you not pondered, I wouldn't have looked.

 

The forums don't just educate through an instructor → learner pedagogy.
