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!

Really enjoy these animations. I'm very surprised this is only 12 frames, very smooth considering. Really does spur me to have a go at one.

Well done.

      Hey everyone !
      Hope your all doing as well as you can be with this pandemic ! Im completely new to this stuff, im looking for some advice on the right telescope kit to buy. I dont want to be spending too much cause like im new and wanting to try it out, just hoping you guys have got some suggestions for telescopes for the value.
      Mainly wanting to look at stars (my stepdad passed away 3 weeks ago and my partner bought a "name a star" for him and would love to see it properly) and im interested in see the planets like the rings and stuff too
      Any help would be very appreciated ! 
      Possibly below £100 the cheaper the better at the minute but dont want it to be so cheap and tacky that i can only see the end of the garden through it lol
      Stay safe everyonr

      Little fluffy clouds.      (terrible imaging conditions due to prescription forest burning)

       
      and this nasty one

       
       
      i actually like the pink,   this is what George Washington's horse riding coat looked like.   (YES, GEORGE WASHINGTON WORE A PINK COAT!!!)

      Finally got to image Mars this year after some appauling weather in the UK. 
      This was my first time out using the ZWO ASI 224MC on a very cold eve.  I think i've probably the maxed out my equipment (Skywatcher 200p) and the location (back garden in the middle of an estate) for this image, so pretty pleased with the results.  Its 15% of 11000 frames stacked using Autostakkert, and Registax used to bring out some detail.
      Equipment used:
      Skywatcher 200p with dual speed focuser, EQ5 mount with dual axis motors Tal x3 Barlow ZWO ASI224mc with IR Filter  Lenovo x270 laptop running SharpCap  Image Processed in Autostakkert, Registax and photoshop
