Jupiter 15May C11

Hi all
I've just registered after seeing the great images in this group. Looks like there's a lot of expertise out there. I've been doing some Toucam imaging for the last year, but would love to produce results like these.

Attached is a montage of Jupiter images from last weekend. Seeing was unusually steady. You can just make out "Red junior" to the upper right of the GRS in the last 2 images. I'd welcome some comments, especially about colour balance, brightness and saturation. Most of the other pics seem to have a more natural look.

Hey Graeme and welcome.

I reckon you have the colour spot on. Now, do you have a good 2x or 3x powermate or barlow?

ROughly how long do you capture the avi for and at what frame rate.

Great entry to the forum!

I use a 2.5x Televue Powermate with the f/10 scope. They were about the best 600 of 1000 frames at 10 frames/sec (100secs). I was interested to read another comment about reducing the frame rate when the seeing is good.

Hi Graeme!

Welcome to the forum! Great first post, some nice detail there and the colour is great.

I'd suggest trying to stack less frames.. 60% of frames stacked is a lot! I'd go for 10 or 20%. The image can be a little bit noisier, but you just have to be careful about what other processing you do.

Can you explain your processing routine?

btw to the forum! how did you hear about us? I notice you're from ASSA - there's been more and more adelaide guys signing up lately, great to see!

yes, 5fps does not compress the data as much as 10fps. raw mode / optimised colour mode is also very good (http://www.astrosurf.com/astrobond/ebrawe.htm )

Chris Go in the phillipines has great seeing with his c11 and collimates on the moons of jupiter for brilliant planetary.

If your mount tracks beautifully, it may be worth giving that a go next time the seeing is right up there with the moons staying relatively still

Westbourne Park - inner southern suburb. Hopeless light pollution, hence the planet photographs.

Hi Graeme,

Welcome.

By looking at your shots you have some experience with processing, very nice indeed.

I don't think there is many if any others in IIS that are regularly imaging Jupiter with C11. The C9.25 seem to be very popular. So It will be great to see what yours can do at optimum seeing.

Thanks for the welcome and feedback. I think I orignally found this site by chance when I was Googling for equipment reviews.

For image acquisition, I'm still using the original Philips capture software. Processing was in Registax 3. I'm just sort of winging it here, not really understanding what the various options will do at each stage. Mostly I just use the default settings. A comprehensive manual would be nice. On the wavelets page I've just used the last 3 sliders, at about 10%, 40% and 90% on this occasion, backing off when the noise and processing artifacts become too noticeable. I always use the RGB alignment tool. Then a bit of tweaking of brightness/contrast, colour balance and a bit of unsharp masking in Photoshop. Although I combined a lot of frames for these, the final images are still not too smooth so I suspect that I've overdone the processing.

Graeme

i would move to qfocus or k3ccd so you don't have to swap out of 320x200 everytime!!

Oops, I may have the date or UT wrong. I looked them up retrospectively after I'd done the processing a few days later. It was about midnight Sunday 14th into the early hours of Monday morning 15th. There was in fact a very light layer of high thin cloud but it was exceptionally still and good viewing for planets.

Hi Graeme, and welcome. There's some lovely detail in here. Processing might have been pushed a bit far as you've picked up which is bringing out the grain, but still impressive stuff. Well done
