Jupiter Feb 11, 2014

Well have been spending more and more time with WinJupos - attached is my first go and derotating 3 images from three separate AVI's per channel and then doing the full combination / derotation and LRGB combo.

All in all, 500 frames per file, so 1,500 frames per channel, so 4,500 frames in total plus Luminance so 6,000 frames all up.

An IR685 filter was used as a the red channel - and considering the very flickery conditions, I am surprised by the LRGB result - I would hate to see the results under really good seeing - and my oh my, what will we see next year when Jove is 60 degrees and then the year after that!

WinJupos really allows you to take processing to a new level - all this whilst Jove is at 36 degrees this year. If you are not yet using Winjupos, cannot recommend it enough, and would encourage you to do so as it's quite easy.


Clear skies,

These came out great John. I have not ventured strongly into planetary captures and take on board your comments about Winjupos. :)

great job john cant wait for next year will be much higher for me to image

Nice images of Jupiter. I like viewing at the moment, but certainly working through the idea of imaging especially with great photos people keep posting here. Keep up the good work :)

Hi John,

Impressive result particularly considering the seeing. I was imagining down the road from you at about the same time and I can vouch for the challenging seeing.

I will have a go at WinJupos.

Do you use the Baader IR685 filter?

Best regards,
Mark J

[John K]

Thanks for all the comments guys.



Hi Mark - yes, I use the Baader IR685 filter which in my mind really is a deep red filter in any case - IR in theory kicks in at 700.

Interesting about comparing the seeing - where are you located and what scope have you got?

Thanks John,

I am in Ivanhoe and I have a 12" F5 from Bintel. FWIW, image from around the same time as you here:

No WinJupos yet...

Nicely done John, WinJUPOS has been a game changer, I generally stack 50% of my data, for Jupiter that gives me approx 7,000 frames per channel. It continues to amaze me how quite ordinary raw data can produce such unexpected results with this process.

[John K]

Thanks Trev - did not realise that you stack such a high proportion of your frames. What time period do you use per channel?




Thanks Mark - did you ever get an IR685 filter? I think this is what is making all the difference for me.

Another image attached showing only 300 frames per AVI channel x 3 so 900 per channel plus Luminance from Feb 9th with the GRS and Io in transit.

I am starting to think that in variable conditions less may be more in that there are less good frames that can be captured.

Thats is crystal clear, so much detail... whats your processing work flow to get these images?

[John K]

See at your other thread the process I follow which has al been put together with the info we all share on IIS,

Hi John,

Currently I go with 58 sec's per channel at 84 fps. My final RGB consists of RRRR, GGGG, BBBB. I only have a manual filter wheel so between my four R & four G channels I lose the time it takes to rotate from R to G and then from G to B, 20 secs all up. That gives an elapsed time from the start of the first R to the end of the fourth B of approx 12 min's. I generally go with stacking 50% of my data although I have had instances in exceptional seeing where I have stacked up to 90% of the data.
