Saturn in IR and CH4 (15/09/23)

[Kon]

I had a decent Saturn session on the 15 Sep, probably the most stable I have seen it this apparition. I captured an OSC image which is ok but the IR and methane came out nice; I created a false colour by trying to match the methane colour to its absorption band pass but of course IR is not blue 😉; more artistic interpretation than true colours. CH4 is 30 min derotation. 8" Dob, asi 462mm, 2.5xTV powermate, IR and CH4 filters.

They've come out well Kostas. Your best Saturn images so far?

I agree and I think it's probably my last imaging of it unless we get spectacular seeing.

Well done Kostas a nice sharp cassini on those think they would benifit from an upscale nicely too!

Thanks Simon. When I resized it at 120% it was losing the sharpness and was becoming softer and noisy.

Very nice images. Why does the central one appear to have a haze/fog around the rings?

Thanks Maurizio. The 'haze' is from overstretching the image to show the weak methane absorption on the globe. I think with more data it should be easier to pop and avoid this.

Spectacular!
