I imaged Mars yesterday morning in addition to the effort I made on Jupiter and Saturn.  Had the sharpening done but never did the image measurement and derotation to see if anything decent emerged.  This is a 13-image derotation from the middle of my data capture effort.  I usually think my stuff is average at best but this Mars might very well be my best image of Mars in a very long time possibly ever.  These are 60s captures stacked 16% of the 18,000 frames in each capture.  Shown at 1.5x capture size.

 

 

I had the image still up on the screen so here it is at 300% of capture size.

 

 

EDIT:  Here is one more (left the rind alone on this one).  I fixed the yips my 16" scope was having (left a travel lock too snug and it was causing a stick-slip to occur in the alt. axis) so I was able to pull in the ROI to only 200 x 200 and get the frame rate up to 425 fps.  This image is 16% of 23,600 frames capture during those 60s.  5-image derotation.

WOW! Talk about persistence paying off! You deserve these results

Thanks much.  It's really about getting out there and catching the seeing just right.  With any random chaotic system you never know when all the variables line up to give you the right conditions.  I'm sure surfers experience the same thing in trying to catch a good wave.  Myriad of other similar situations.  Who knows what I missed this morning by choosing to NOT image today.  It drives me a bit nuts but I have to catch up my sleep at some point.

Ooh! I like that image very much! Great work, Don. 

[Ittaku]

Very nice! Maybe 300% is a bit too much though

Agreed but if I had done 3x drizzle that’s where it would have landed. No new information in the 3x image to be sure but it’s easier to see on my phone.

Nice shot! 

[dcaponeii]

Nice shot! 

Thank you.  13 x 18000 x 0.16 = 37440 "shots" to be more accurate.

Very nice, Don! Lots of detail. Mars is still pretty small!

[KMH]

That is a terrific result!

I know.  At something like 7" it makes me think it's worth going after some of the planetary moons after all if the seeing warrants.

That is a terrific tiny Mars!

[leoyasu]

Plenty of details, nice!

[Tulloch]

Fantastic images Don, I also prefer the first one at 150%.

 

Great colours too

[Vega700]

Very nice results. I like the small one..

[Kiwi Paul]

Fantastic Mars result.

Cheers Paul

That is excellent Don and your handling of colour balance is great.

[marvyyk]

Great images!

I've been practicing with the de-rind tool (it was giving me trouble with Mars data and I did not use it on the images above, preferring the old fashioned way of selection tool and darkening and softening the boundaries of the rind)

 

I got pretty good result in my latest effort.  This is a fresh 9-image derotation having used the derind tool on the batch of images that went into the derotation and no additional work on the rind after derotation.  I had hoped to place it beside the original image but the time limit for editing has been reached. (and I always throw out earlier processing attempts when I'm dong something new.)

Don, excellent Mars! Your de-rinding procedure will be very helpful here and will hopefully be available on the next WaveSharp version soon.

Correction.  It's Cor's de-rinding technique.  I'm just a tester in this enterprise.  In fact, although I can take a little credit for pushing some of the animation items, Grant was the impetus for getting us back on working the rind issue.  Instead of blurring away the rind, preventing those areas from being sharpened all together certainly looks to be a really great improvement.  Implementation of all our the ideas that we testers come up with are implemented through Cor's expert knowledge of processing and programming.
