Jupiter 18-Nov

[Troy]

Hi,
Here are some pictures of Jupiter and Io in bad conditions.
I have made an animation but this time it's Ganymede disappearing behind Jupiter here (http://home.exetel.com.au/celestial/html/Animation/Jupiter%20&%20Ganymede%2018-11-11.html)

Excellent images and animation Troy. That Ganymede is huge. :)

Very nice work Troy.

Nice sequence Troy. Conditions can't have been too bad, you've still got quite a bit of detail there. Thanks for posting.

Cheers Guy's. At full scale the images look pretty ugly these have been scaled down a fair bit.
I have attached the animation of Io and shadow :)

[Clayton]

That's VERY nice work Troy :thumbsup::thumbsup:

Excellent work Troy.

I wish I had those bad conditions at my place. For me they look excellent.

[Troy]

Thanks guy's,
When I rate the seeing I use poor, bad, average, good and excellent as a guide. I then compare the nights data to past images obtained at the same site and going back about 3 years. When I look at some data from the past I think bad is the category it fits into, remember full size images not scaled down version.

Beautiful images and animations, Troy. Lovely work.

It's now IOTW (http://www.iceinspace.com.au)

[atalas]

Congrats on IOTW! truly wonderful work Troy.

[Greg Bock]

Sensational images Troy, love the animation too.

[Quark]

Nice work Troy, reckon you should maybe reevaluate your estimation of the seeing though.

Even taking into account the resampling down of the images there is detail in them that just isn't there in bad seeing.

Top Stuff:thumbsup:
Cheers

Wow Mike, that was a surprise cheers. :eyepop:

[Paul Haese]

Fantastic and congrats on IOTW!

[Troy]

Cheers
First time IOTW!, pretty special. :D

Great stuff, any more info on equipment and processing techniques?

People keep bagging out SCTs, but the best planetary stuff I see tends to come from SCT owners.

Excellent images Troy. Regards Ray

Thanks Peter and Ray.

Not sure if you have seen my equipment page here (http://home.exetel.com.au/celestial/html/equipment.html)
Mike Salway has a tut on this in the articles page and another good one is from Paul Haese website how to section.
I use ninox: To crop and centre the image. This program works well for low end and midrange mounts and allows registax to do a better and faster job.
Registax: Align, stack and to apply wavelets.
Astra Image: After registax I like to apply deconvolution filter and rotate the image.
Winjupos: Image measurement and to combine my rgb channels for a colour image.
Photoshop: Adjust colour, sharpen image(unsharp mask and sometimes highpass filter) and size image to taste.
That's it

A lot of people from around the world produce very good images from mass produced sct scopes. For the price you pay they are not bad at all. Mind doesn't seem to suffer from image shift or mirror flop etc..., maybe the larger sct's suffer from this :shrug:
The high focal ratio and being a compact scope is really handy for me as I set up my equipment, image and then everything goes back inside the house :juggle:

[strongmanmike]

These are great images Troy, beautifully processed too and if this is less than optimal seeing I look forward to what you will show in good conditions :thumbsup:

SCT's and Newt's can both do excellent work for planetary imaging.

The 14" SCT's are well known across the world now as most of the world's best use them (Damian Peach among them). They have long focal length, plenty of aperture.

But there's plenty of the world's best using large newt's - Anthony (bird), Trevor (Quark) and Wes Higgins to name but 3.

They each have their strengths and weaknesses.
