MLV-App did a big part of the work in this picture. Without processing with MLV-App, I didn´t get any details:

how do you compensate the atmospheric turbulences?
when i look through my maksutov mto-11ca i quickly tend to forget all ideas about shooting photos of planets.

Mars. This is sick. Awesome.

Wow nice one!

Don't have proper reach for this, don't have a telescope.
My maximum reach is 280mm (70-200 with a 1.4 converter)
But I like to shoot the sky now and then, also happened to shoot a video of Mars last Teusday to Wednesday night.
A lot worse then your shot, but I think the result isn't that bad for 280mm maximum reach

https://drive.google.com/open?id=1RBadPYSXcnF1C5fm-ZS3SKewGmHQRqP2

Used some super resolution trickery to get some more reach.
I've resized the frames to 4x times the original size, and used pyflow to smooth things out:

after that I additionally rescaled it 2 times the size in Davinci resolve, so I guess the size should be comparible to 4 x 2 x 280mm = 2240 mm

I thought i would throw this at all of you, here is a short timelapse video
of Mars Rising with Milky Way, shot on 07/13/2018 starting around 11:15 PM Pacific Standard Time,
at McClellan View Point, Gifford Pinchot National Forest, Washington, USA. My Original purpose was
to catch the sunset and do some light painting but tourist with questions side tracked that idea and
got all this by mistake, only problem heading back home at 2:35am in the morning a snag fell across
the road almost hiting the passenger side of the vehicle, woke up real fast after that.
Canon T3i/600D DSLR Stats:

@g3gg0

Seeing and turbulences wasn´t too bad. But Mars was not very high above the horizont (ca. 14°), so much athmosphere between Mars and me.
The reason for the missing details was anaoter. Since one or two month there is a global dust-storm on Mars. And tihs storm draws a curtain over big parts of the surface.
To minimize the distortions of the athmosphere, I waited for a moment, the stars wasn´t twinkling too loud. An I did lucky imaging. That means recording a short video (18.000 frames) and taking the best of the frames for stacking.

As a worm-up for Mars I recorded Jupiter. The altitude of Jupiter was similar to Mars, about 14 degrees. I saw a nice little planet through the okular of the telescope (focal lenght 6 meter) and I saw clearly the four "galileischen Monde". See the result of this worm-up:

@Danne

ThankYou

@Levas

Hihi, that´s what I did years before, as I didn´t had a telescope yet, just 300mm tele + 1.4 + 1.7 teleconverter

Nice video.

@pnwhikerz

Thanks for sharing.

Levas · « **Reply #6 on:** July 22, 2018, 11:10:36 AM »

Always like photographs of planets and other deep sky objects, but I can't get myself to invest in a telescope and tracker, afraid that that is going to be a jump to an expensive hobby. (And photography is already an expensive one

. )

Actually a little curious how your MLV files are looking.
Are you maybe willing to share a MLV file of your mars or Jupiter shot ? (If not no problem, just curious to see the original file and see what I can do with it in post proces.)

g3gg0 · « **Reply #7 on:** July 22, 2018, 02:45:01 PM »

holy crap. this singe MLV and the resulting picture right next to it blew my mind.
didnt expect that someone could recover so much detail from such single frames...

escho · « **Reply #8 on:** July 22, 2018, 02:54:49 PM »

Hey g3gg0, uploaded the single frames just a minute ago to my websitea and you just answered. You are quicker than the light

OK, to make it officiell. I uploaded single frames to teh threads of Jupiter and Mars to show, what you can get out of such a video. Her again the Links:

g3gg0 · « **Reply #9 on:** July 22, 2018, 03:04:20 PM »

this is so impressive. wow. then i might try my cassegrain and see what i can get with it.
any idea/estimation if the MTO-11CA (russentonne) is capable of getting something useful?
or is its 1000mm focal length lost hope and i do better saving the time?

escho · « **Reply #10 on:** July 22, 2018, 03:17:20 PM »

Give Jupiter a try, the Russentonne is not so bad from what I,ve heard. But the result will be a bit small. Remember, I recorded with 6 meter focal lenght. Maybe you can add a TC to your MAK . 1000mm focal lenght is fine for the moon. And to freeze the seeing, take short exposure-times (1/64 and quicker)

Levas · « **Reply #11 on:** July 22, 2018, 03:26:19 PM »

Wow impressive post processing going on there

I actually saw the reply of Geggo and went to your linked images again, saw the single frames, thought I missed them the first time, but now I see you just uploaded them

Too bad I'm on a mac, autostakkert seems to be used by a lot of astrophotographers and giving some real good results.

escho · « **Reply #12 on:** July 22, 2018, 03:35:06 PM »

I am running autostackert (the beta version) from Linux openSUSE Tumbleweed using wine. Same with deepskystacker and fitswork.

Levas · « **Reply #13 on:** July 22, 2018, 05:08:37 PM »

Aha, got Autostakkert running under wine

Let's go to my Mars files again

Very nice @escho! You'll try to get some nice pictures tomorrow of the lunar eclipse?

escho · « **Reply #15 on:** July 26, 2018, 09:30:45 PM »

Yes, I hope the weather is fine. I´ve planned a landscape-timelape with Mars and Moon (EOS600D) and some pics with my little MAK and the 6D (1500mm focal lenght)

Danne · « **Reply #16 on:** July 26, 2018, 09:47:59 PM »

Brilliant.

masc · « **Reply #17 on:** July 26, 2018, 10:06:58 PM »

I am very interested in the results!

escho · « **Reply #18 on:** July 28, 2018, 07:49:39 PM »

Here are the results of the lunar eclipse, text is in german...

Live-Blog yesterday: https://sternenkarten.com/2018/07/27/totale-mondfinsternis-update/
Pictures: https://sternenkarten.com/2018/07/28/mondfinsternis-und-marsopposition-das-ergebnis/

The weather was bad and no chance to get the teleskope aligned in time. Timelapse wasn´t possible, because there was nothing to timelapse only clouds. But I found some nice stuff in the results. ML was involved with it´s intervalometer and the mirror lockup. Cameras used 600D and 6D. Focal lenghts 24mm, 100mm and 300mm

g3gg0 · « **Reply #19 on:** July 28, 2018, 10:43:24 PM »

didnt have much luck either.
could see the moon the last 30 minutes, but with my gear it was all too dark to capture properly.

here a 2500-image merge of the moon right after it left the umbra

escho · « **Reply #20 on:** July 28, 2018, 11:20:44 PM »

Nice!
Could you share you camerasettings, please? I had the best results with ISO6400 F 1/5.6 2s on my 6D with 300mm-lens (CR2). Video was not possible.

Levas · « **Reply #21 on:** July 29, 2018, 01:53:04 AM »

Had to work till eleven in the evening, so I was too late at home to shot the full lunar eclipse.
Since the eclipse was already halfgone, I went for dual iso shots, to capture both the bright side of the moon and half of the eclipse side.
Used MLV recording in 5 x zoom mode.
-Dual iso 200/6400
-Shutter time 1/40th seconds per frame
Stacked 8 x 16 frames together with the kandao raw+ software and stacked the 8 stacked frames together again to one frame (so a total of 128 frames stacked together) and edited the resulting DNG in Lightroom.

Danne · « **Reply #22 on:** July 29, 2018, 03:44:02 AM »

Wow, could you upload the original file?

masc · « **Reply #23 on:** July 29, 2018, 09:54:54 AM »

Ah, what a shame @escho... here some km in the north of you we have seen a very little more. We also had some clouds but I don't have the right gear to make good photos...
You all got nice shots!

1. MLV, 1920x1080, ISO200, 1/33, Maksutov MTO-11CA
2. mlvfs -> lightroom -> TIF (without editing)
3. ~4200 frames into autostakkert 3.0.14 to stack 60% of the images
4. used fitswork to apply a handcrafted deconvolution filter
5. applied some gamma correction

my first real try of this toolchain.

the total lunar eclipse was close to impossible to shoot properly.
had to use FPS override to 500ms exposure time to see a faint image of the moon with ISO3200.
then shot a MLV with 1000ms exposure time, but with the moon being imaged only partially (crop_rec)
but autostakkert has trouble detecting the motion properly
