Jupiter - Io transit and grs 17/09/22

[barkingsteve]

Always seem to struggle with planets but had a go the other night. C925 and 294mc pro with a 2.5x barlow. Stacked in AS3 best 40% of 3.5k and 1.5 drizzle, Wavelets in registax and final processing in Gimp.

Seeing is everything, keep trying and one night it will come together ... Still a good image though.

Nice image. I had a C9.25 a few years ago - it gave such amazing views of Jupiter, I really want one again   You've caught the transit really nicely there!

I caught Jupiter to about the same time.

Seeing was the problem that night for me to, my 10" SCT on good nights comes close to my big refractor but not that night, smaller aperture 6" and no central obstruction helps with seeing. I also used a blue green filter and a fringe killer, this helps to sharpen up the features as does monochrome, colour is hard when seeing is bad, each colour (RGB) moves around at a different rate, blue the worst, red the least, you can see this in your colour image as it has a blue halo and blue haze indicating seeing.

Your eye can keep up with the seeing, you ignore the bad bits and absorb the good bits to build up an image so when you get those sparkling moments you see everything and it's awesome.

Just keep taking images and hope one captures a moment of clarity.

This was my best shot, I'm no expert I prefer visual but sometimes make the effort, sadly I lost Io's disk, it was very visible early on in the transit and imaged well, no idea where it went, still leaving a good shadow though.

Cheers Rod
