Hi guys.

Had a crack at Jupiter last night because I wasn't sure when the next opportunity would be with the weather closing in.

This one's from around midnight.

The usual: Gain 40%, gamma 30%, 10fps, 1/30th sec, brightness around 50%, saturation 50%.

Humidity a problem again last night, at 75%, with seeing 3/10.

Just a little wavelets in Registax. Couldn't be bothered with any other post-process. Don't think the data's worth it

But just had to get out there anyway, eh!

Sorry about the Mitchell 75% resize. It's the only way I could get it to look any good.

Oh yeah. This is with the 9.25

That looks great Matt, nice and round and good colours. At that size it could probably do with an unsharp mask. You should try just doing a split/LR/recombine in AstraImage.. it could give it a sharper look too.

I'd like to Mike, but my skills are simply very average.

I've performed the process you're talking about on other images but it never seems to do much for my images. Must be something I'm doing wrong

You wanna have a crack? Would love to see what someone with your skills can bring to one of my images.

One question I do have regarding AstraImage.

After splitting the colour panes... and clicking on them to perform LR or ME convolution, the new panes appear as if an automatic histostretch has been carried out and the image is too bright. (simple terminology).

Can anyone help? Is there some kind of default histostretch setting which can be ticked off/ unselected?

Cheers

i'd be happy to have a go, Matt.. send me one of your avi's (your best?) or upload it somewhere?

They zip up pretty well.

And yes, when you convert to greyscale it does an automatic histostretch. I can't find any way of NOT doing it.

Hi Matt, it's a great view of Joop this face isn't it, the swirls following up the GRS, red jnr and so on. Nice capture

That histostretch thing... I find sometimes it just turns itself off, I don't know how and don't know why it happens sometimes and not others. If I shut the program down and repeat it often comes back on. Maddening! It might have something to do with whether you have the histo stretch and intesity balance check boxes checked during the Registax process, but I'm merely guessing. If you find out let us know
