Jupiter & Saturn 24th Sept

[symmetal]

Had a go at Jupiter, Saturn and Neptune tonight. Seeing nowhere near as good as on the 19th, so Jupiter's not looking as good as the image I posted then, even though it's 2 mins worth rather than 30 secs.

Both images 5mS exposures, 120 sec videos at 200 fps, 10" LX200GPS, 2x Powermate, Zwo ADC, ASI224MC.

Jupiter gain 350 and 15% stack, so 3500 frames, Saturn gain 490 and 20% stack, so 4700 frames, Processed in AS3, Registax wavelets and Photoshop.

If anyone wants a go themselves, I've included the raw stacks. 🙂 

 Jupiter, 2022-09-25-0002, 5mS, 200 fps, 15pc of 23000 frames.tif

  Saturn, 2022-09-24-2204, 5mS, 200 fps, 20pc of 24000 frames.tif

I need to increase the offset for Jupiter as Registax creates a wide black clipped ring around the edge so I had to clip all the background. Saturn doesn't for some reason despite similar processing.

Europa is also featured. If I'd been a few minutes earlier I'd have had Io and Europa just off the right edge.

Having trouble stacking Neptune as AS3 seems to be locking on the noise, as I used very high gain with 20mS exposure and the image is too dim to separate from the noise. PIPP was able to stabilize and centre the planet OK but AS3 is causing the stacking to jump about again.

Looking good!
You get some great images with that scope. 

Thanks for sharing the stacks, much appreciated.

Very nice especially your Saturn.

Regitax wavelets and RGB balance, PS image reduced by 10%, saturation increased and adjusted to be warmer.

@Laurieast Thanks Laurence. It does give good images on the planets, though For the Moon, I find that a refractor and Powermate gives better images. 🙂 I do have to check the collimation each time I wheel it out the shed as it's likely to have gone out. It's possible the Bob's Knobs are a little looser in their threads compared to the originals or the large temperature changes particularly in the summer make them shift slightly. 

Your image looks good. You just need to set the background colour though. 😉

@Kon Thanks. In poor seeing I think Saturn gives a better image as you don't need such detail to make it look good. The rings do that by themselves. 😀
