Borrowed from another thread...:biggrin:
Tim that sure would be an interesting challenge. I'd love to see an F50 image.

You didn't say it had to be good...:wink:
This is from about a month ago or so. With the DMK and a 5x powermate, seeing only about a 7/10.

Wow, thats huge mate. How many frames? Is it feasible to actually shoot Jove at F50? I mean can it yield great surface detail. I imagine the seeing would have to be perfect.

I believe it's possible, yes, but you are correct. The seeing/transparency would have to be at least a 9+ to probably get any decent detail.
As far as frames go, I know when I'm capturing, I always capture at least 3,200 frames when I stop the capture process and have another go. That way by the time 'quality control' in RSV4 get's through picking the best 80%, hopefully I will have 1000+ frames to stack and work with.
As you well know, if the seeing isn't good the image does quite a bit of moving around when your recording the AVI's. And believe you me this one had it's wiggle on...I think I only wound up with about 400 or so stacked frames, so the use of the wavelets in RV4 to bring out any detail was minimal.
I hope to have another attempt at this soon being it's Jupe' season.
Now about that one @ F/100?:biggrin:
