April 4th UT Mars & Saturn in good seeing.

[Quark]

Hi All,

Imaged Mars last night in reasonable seeing , have good coverage from CM 138 to CM 160 which I think is the region of interest for Wayne’s cloud.
Have attached 1 RGB & 807nm IR data set along with animations of all RGB & IR data covering 90 min’s of Mars rotation. Olympus Mons is well resolved as is the Propontis Complex and the clouds over the Tharsis volcanoes. Reckon this is about the best resolution I will get at this alt as Mars continues to shrink.

Moved on to Saturn and the seeing was good, this is the best 807nm IR data I have ever captured of Saturn, such a shame that there are no SED’s active now. Have attached 1 RGB & 807nm IR data set along with animations of the best RGB & IR data. In the RGB animation there is some nice structure along the Southern edge of the great storm remnant and there are some faint clouds in the NEB, this is also remnant material from the great storm that has been distributed further South by the interactions of the various opposing jet streams that frequent the Saturnian atmosphere.

The IR animation at first glance looks a bit bland but of interest is the ripple along the edge of the intersection between the EZ & NEB. A closer inspection shows movement of spots within the NEB that are associated with the features appearing in the same region in the RGB animation.

Thanks for looking.
Regards
Trevor

wonderful set of high res data Trevor. all excellent, but the nearIR images are outstanding and show exceptional detail. thanks for sharing. regards Ray.

Wow, stunning. And the animations are great too!

Impressive set of data Trevor. Great detail on Mars, and nice cloud action on Saturn.

You sure are getting some nice shots Trevor :thumbsup:
Very nice work as usual:)

[Paul Haese]

Nice Saturn animation Trev, heaps of storm detail and nicely rotating around the planet. Interesting deviations in the NEB at the junction closest to the equator. Like that belt has a large disturbance in it.

Wonderful detail resolved in your images Trevor. Thanks for the views. All the best.

Lovely work Trevor. Mars came up very nice. I'm sure you won't take any of my comments the wrong way other wise I wouldn't bother, but my personal preference for colour balance on Saturn is a bit less green, & this IR image/animation looks a clipped around the edges on my computer. I'm guessing the clipping (mainly at the pole) is unavoidable perhaps in IR..? Love the ring details you are squeezing out on Saturn!

Thanks very much Ray, it has been pretty full on over the last few days for sure and congratulations on the stunner that you produced also.



Thanks very much Werner, appreciate your comment.



Thanks very much Ivan.



Thanks very much Rob.



Thanks very much Paul, the ripple is interesting, not so noticeable in the RGB as it is in the IR, be interesting to hear Leigh Fletcher's thoughts on it.



Thanks very much Lester.



Thanks very much Asi and off course I appreciate your comment, I only know one person who I would just rather not deal with. Now that you have dabbled a bit with the DMK I reckon you would have an appreciation of the work that goes into capturing 3 channels of data. Regarding the colour, it seems to have changed a bit over the last couple of apparitions, depending on the tilt of the rings. To my mind the colours of Saturn should be creams and browns and the rings should be neutral, grey or white. At the moment I have been basing my final balance toward achieving whitish rings. As you have mentioned in another of your threads, the lighting makes a big difference when processing and I find I get different results if I do it in natural light with the blind on my computer room window open to having the blind shut and the room light on. With reasonable seeing I am starting with Mars at 9pm and going through to 3:30am local with Saturn, so much data. I always try to get it processed to post it the next evening before I start over again so my initial processing is pretty quick. For sure, all of my best data will be reprocessed as I get runs of crook weather.
Regarding the IR & the North pole, I think it is just how that region relates to 807nm IR, it does block a considerable amount of light. As you know, with good seeing everything just fall into place and much lighter applications of sharpening are the go to reveal fine detail in the rings & within the atmosphere.

I'm hearing you, regarding the one you'd rather not deal with. Same, & I've given up posting there altogether due to him & a few others. Anyhow, enough time spent on that.

Yes, certainly appreciate the work with Tri-imaging. Could be my monitor as to why I could be seeing a bit too much green in the Saturn image. I do note though, that if I choose 'auto white/colour balance' in IC Cap. with the DBK it does turn slightly green so you may well have spot on colour afterall..

Thanks mate:thumbsup:
