Hi guys.

2 clear mornings in a row! Who would've guessed it!? Very tired today though, after my daughter Abbey was up half the night with tonsilitis pain, I was then silly enough to get up at 3:30am for the last half of a GRS transit, and the first half of a Red Jr transit. An Io shadow transit was coming up, but the seeing deteriorated and I had to shoot off to work.

It was a rather frustrating morning, as the seeing was mostly average (4-5/10) followed by moments of 7-8/10, and then back down again. Out of 11 avi's, I think i'll only be able to salvage 1 or 2 decent images - here's 1 of them.

The version on the left is after usual registax and astraimage processing, the image on the right also includes a run through NeatImage for sharpening, noise reduction and contrast enhancement.

Shot @ 10fps, 107 frames of each channel stacked.

Feedback welcome.

Very well Mike.
Thanks for share it.

Two for the price of one! Excellent, Mike, if there were Jupiterians they'd be very pleased with how you show off their planet. Alas, it's just we who are amazed.

Hope your daughter feels better.

Great shots. What kind of telescope and camera are you using?

Thanks andy.

I use a run of the mill 10" GSO Dob, on an EQ platform with a ToUcam webcam.

This morning, I processed a different avi from the same session.. I think it turned out better.

If you don't mind, some more detailed questions...

How long do you take each AVI? I originally started taking 500-600 frames but am now tarketing 1,600-2,000 (about two minutes).

How do you evaluate an AVI? Is it only after running it through Registax to see the result or do you have a short cut evaluation process?

Do you realign your image with a processed version? Or use the feature to create a 50-frame or so sharpened master for optimization?

Thanks and hope I'm not being too demanding,

--Andy

Mike: congratulations on the APOD!

Oh cool Mike! You deserve an APOD spot. Or APOD deserves you.

Thanks Wolverine for being so alert.

Thanks a lot!

I'm very pleased to have had my jupiter image/animation on both spaceweather and APOD!

For Jupiter, 90 seconds only. At the image scale i'm working at, any longer and there'll be rotational blur. The number of frames depends on the frame rate - I use 5fps in great seeing, and 10fps in anything less.

Basically registax.. I can usually tell from the raw frames if the seeing was any good. After the initial alignment, it sorts the good frames to the left, so I drag the slider all the way to the left to see what registax thought was the "best" frame. Experience tells me, if I can't see good detail in the raw frames, there won't be good detail in the stacked image.

I use the "Create Reference Frame" function before optimising. I use the default 50 frames usually, and do mild/medium wavelet processing and then use that as the base for optimising. That usually does a good job of ranking the best frames first, so I can drag the stackgraph slider down to stack 100-200 frames.

Hope that helps!

Mike,

This is great info. There is nothing better than understanding the details from someone who is doing the work well!

Thanks,
