Last night was the best seeing around this way for almost a month... Here's an image from about 3:37am this morning.

cheers, Bird

ooooooo yes, this is gold!!!

anything different processing with this one, it is fantastic on my laptop.

is there any way to rgb align different areas in say photoshop???. ie align the blue on ganymede,

Gee with this one, Dennis, Rob, John, Paul & Chris go with surface detail on callisto, this has been an excellent day for jupiter. Just like xmas

Awesome Anthony, it's been a while coming from you! You've had bad luck with the seeing, same as me for the past 2 weeks.. nothing!

Shame you missed red and jr, but you got a great ganymede. Well done.

I was out in time for Oval BA at 1am, but the seeing was very bad until about 3am. I have some data recorded but I doubt I acn do anything useful with it.

The seeing was probably about 7.5/10 for this image.

cheers, Bird

ok, i am now at my crt and this image is officially the best looking one for both monitors of mine ie my dell laptop and a crt. Before that, it was one of mikes in his photo gallery

both of these when full size have glare in the middle on my laptop, but on the crt are fine.

Bird, are you able to do a 1.5 resample at some stage, so i can compare all three of these world class images?

Goodness me, dont think I have seen so much detail in an amateur image before of Jove! awsome!

Hi Anthony

That is a very impressive Jupiter image, nicely resolved detail and with the bonus of features clearly visible on Ganymede. Well done and kudos for persevering with the seeing conditions in Canberra.

Cheers

Due to a bug in registax I can't use resampling with 16 bit data...it causes registax to lose its lunch big time.

There's always the option of resampling the images before I feed them to registax, but I've found problems doing that, it makes it harder for registax to lock onto features if you make the image bigger.

I'm hoping for much better conditions on my trip in a few weeks, the seeing wasn't really all that good last night.

Thanks for the comments, I'll keep trying for some really good conditions.

Lovely detail on Ganymede Bird, and Jove ain't too bad either :thumbsup:

thanks bird,

I spent about an hour last night alternating between my latest, chris's, yours and one of damians last year. Now I know damian may bust free from the pack again after this trip after throwing the c14 at jupiter, but as I mentioned before at full size, it is only that final smoothness / slightly better naturalness that damian seems to beat everyone at.

It may be artistic skill, or something technical like unsharp mask / wavelets etc.

I cannot wait for end of april for damian's results and then yours to make some more detailed comparisons.

This is so much fun. By the way, if money is kind to me, I wouldn't mind adapting a 16" GSO dob with active cooling for next years opposition etc, not sure of their focal length though

Well, I think Damian is stil the man to catch. Where I get fleeting moments of 9/10 seeing or better he's travelling to places where 9/10 and higher is normal. And I'm sure he has some secrets in processing as well.

I've been eyeing off some of those small pacific islands like Vanuatu etc. Would be an interesting experiment to spend a month or so on one of them with the scope.

Be careful about wanting more aperture - I'm finding 13" to me much harder to get right than 10".

Well done Anthony, excellent result.

no, too much glass, exaggerates any thermal problems and also exaggerates bad seeing...

Yes, bigger aperture will do this to you won't it. :doh: Just another factor why I Have not done too much imaging with my 12.5" Parks newt & went the C9.25" route instead.

Hi Bird, what can one say. Detail within detail within detail. I've been pretty happy with some of my jupiter shots lately, but this is just in a class all its own. Great stuff!

cheers,
