Better Jupiter from Melbourne this evening

[John K]

Seeing got to 7/10 in Melbourne and starting to make some progress on the processing side.

All images have been resampled 1.4 times in Bell, with approx. 300 frames split into R, G, B and processed in Registax before being recombined in AstraImage and using ME Deconvolution and some unsharp masking. Other than a 0.9 Gamma, I did not adjust anything else.

There are 3 versions attached based on how much wavelets processing was applied before being taken to AstraImage. The first one had close to nil wavelets applied (I did try putting in back into Registax after AstraImage with very limited results).

Comments and advice as always welcome!

That's excellent John. The moon is amazing! Seeing was not bad tonight, but the haze just got progressively worse. I was really hanging out for GRS transit. Had the big dob set up and cooled but as GRS came transparency went.

Now you're cooking with gas, John! Well done!

Ganymede is simply stunning. You're making amazing progress now.

I prefer the planet in the second attachment, and the moon in the 3rd.
Nice job.

nice detail, well done! I like the third image, especially with the moon in it!

Ecellent John,

I like the third image although all are very good=colour and detail.

[asimov (John)]

Very nice mate! Well done.

Great Work John

Those images are very detailed.

For a newbie such as myself how much preparation goes into getting your telescope "perfect" for imaging, considering your telescope's fast f ratio?

this is even BIGGER than Lester's!!!

OMG what image scale and detail, yet still so smooth, even the detail on Ganymede

Thanks for the comments guys.

Ronnierigel all I do is wheel my scope out (it's on wheels) and let it cool down, collimate, focus and use. Other than cooling down, it takes me 5 minutes to set up. Being in a steel tub and open truss, the scope cools down rapidly, and I also use an air fan to cool down the mirror faster if need be.

Collimating with a Laser is very easy, and generally it just takes a few minor tweaks of the screws on the secondary and the primary before every use or after I go to another part of the sky. Having a premium laser focuser is the key.

Focusing is quite easy as I have a JMI motor focus and the Torus optics focus very precisely to the point where I am chasing the seeing most of the time. Having a 3 digit counter on the focus motor helps.
