Mars rotation time-lapse 2020-09-22, UK, personal best!


Recommended Posts

Hi everyone. Thanks for looking. I know we're inundated with Mars pictures at the moment but I've not seen buckets of time-lapse and this marks a significant personal best for me so I really wanted to share it. I've not had seeing this good for a long time, especially with a planet this high above the horizon (I'm looking at you Jupiter & Saturn.....).

Only 12 frames spread across ~1 hour, but nice to see some movement. One single still as a bonus too :)

Edit to add acquisition & processing:

  • Skywatcher Skyliner 200P reflector (off my dobsonian), 1200 mm, unbranded 3x barlow for 3600 focal length, f/18
  • Skywatcher NEQ6 Pro mount
  • ZWO ASI120MC-S - gain 33, 20 ms exposure, 2000 frames per video

 

  • Each video recorded with 5 minute spacing. 12 recorded in total.
  • Stacked in Autostakkert 3, best 30% of frames. Wavelets, colour balance, and tweaks in Registax 6. GIF assembled in Photoshop with a few final contrast and levels tweaks.

That's a superb animation, really well done! Loads of detail and can barely see any difference in the frame quality as it goes, the seeing must have been nice and consistent. Is this with the 200p in your signature? The frames of the animation look slightly more detailed than the singe image.

Thank you! Yes, the seeing just seemed... brilliant all the time I was out there and I couldn't believe how stable it was across the ~1 hr of the time lapse.

You're right about the single still detail being less than the animated frames - that's probably just my own processing though. I think I took a lot more care with the animation (in fact, it was my 3rd go that I actually uploaded). I just love the movement though so I couldn't focus on the stills 😄

Edit: Forgot to add, yes, it's the 200P reflector in my sig that came off the dobsonian. It's a nightmare to locate objects with it at that FL but once you do, it really shines.

That's a superb animation. I was imaging Mars at about the same time, but with mono RGB&IR filters, the jumps between stacked colour images makes smooth rotation animations difficult. I must try to work out how to do that; I think WinJupos has a tool for it but not sure....

Great animation and nicely processed too.

Thanks, that means a lot. I am often guilty of over-processing a lot of my astrophotography data (especially of deep sky) and I'm trying to bring it back a notch, do without a little detail but keep it looking "real". I'm just so pleased with how this turned out given the awful seeing / low altitude I've had with Jupiter for the last year or 2 of trying!

      Ingenuity has just taken its first successful up and down flight on mars!
      Amazing considering there's almost no atmosphere to fly in.
      Only a couple of pics so far at the end of the broadcast but I'm sure more to follow.

      This image is a compilation of my captured images of Mars during this years (2020) opposition season of Mars. All of the images were taken using a 8" SCT at 6764mm focal length (f33.3) with an Celestron Skyris 618C CCD. All of the images were taken with the same telescope at the same focal length so shows the size of the martian disc as it was closer, at opposition and further from Earth.

      I was very pleased to have captured this.  Like a whale breaching the surface of an ocean this sunspot floated to the surface for a short breath of life  ; awake for just 20 minutes- it decided to fall back asleep under the ocean of boiling  ionized calcium plasma-
       
      Thanks for looking!

      Hello all. I’ve tried a few times in the last month to image Mars but have had very little success. Although a decent size, Mars is very blurry and wobbly. I am fairly new to the hobby, but I would say it appears to be poor seeing conditions. 
      I am using a Celestron 6SE and Canon 600D. I have tried 2x and 3x Barlow. I focus using a bahtinov mask (on stars). I used movie crop mode on various ISOs and exposures, stacking at least 3000 frames (keeping the best 1%, 2%, 5%, etc).
      Is Mars too far away now? Or am I underestimating how rarely you get a night of good seeing? How do you find out when the best seeing will be?
