(yet another) Jupiter, July 25

Making the most of the weather while it lasts...

This is from last night, more excellent seeing. This is not the finished image, this is an intermediate that I use to go back and refine the raw data before I make the final image, but I wanted to post it anyway, the end result will be noticeably better :-)

edit: replaced this image with the final one.

regards, Bird

Stunning bird, and that's just the intermediate image

I, for one, would love to know some of your processing tips. What do you mean by using it to refine your raw data?

Yeah, the moon had finished transit about 30 minutes earlier and is off to the lower left (outside the scope of the image).

Here's the refined version, made by the "morhping" option to ninox, this is where you provide a reference image and ninox morphs (distorts) all the raw frames so that the major features all line up with the reference image. The end result is a sequence where all the primary features are in exactly the same place.

One day soon I'll write up a page about it, but it's described on the ninox page (http://www.acquerra.com.au/astro/software/ninox).

So anyway, here's the resulting image, not that all these images are resampled to 150% of original size.

This image is larger than previous images because I added more extension onto my 5x powermate last night, getting to about 14.3m focal length. Jupiter almost filled the height of the ccd :-)

regards, Bird

Paul, the last bracket in the link has been hyperlinked - you'll have to cut-&-paste.

And amazing stuff Bird!!!

aah, ok - I'll fix that shortly, looks like an old copy of that page has been put back in one of my updates a while back and is missing some extra stuff.

Ok, it's fixed now.

The morphing stuff has been there for about 18 months, originally written for processing lunar images, but if you have good quality planetary data then it seems to work ok on it as well.
