Inspired by Mark and his excellent Mars opposition image, I thought I'd have a crack too. I decided upon a double spiral arrangement, which added another layer of complexity, and couldn't be bothered to put in all the dates. It's really quite amazing how much it changed in size smile.gif

This is amazing. 

 

Almost is an optical illusion if you stare at it a certain way too :)

Good work! You got a very consistent colour tone throughout too.

I like the spiral. In 2018 I tried to capture the pro- and retrograde movement as well in my assemblage but there was too much going on in the picture and it collapsed under its own sophistry!

Thanks all for the comments and the likes :)

Thanks Mark, the colour consistency is easy when you process the images with the same colour settings :). However, I was surprised when I created my Mars map and the individual frames didn't match up colour-wise.

Very nice work and presentation! waytogo.gif

 

The spiral pattern is almost hypnotic. Eyecrazy.gif

Nicely done, looks good in a spiral like that. That ice cap really shrank in size from what it was earlier in the year.

D@mn - I just found an error in the original image (and now it's too late to edit my original post frown.gif). There was an error in the size of the second last image, and I still have no idea where it came from. It looked wrong when I first created the composite so I checked and double-checked the original frames I captured, and the size difference was present. However, it was still bugging me so I just did a proper investigation, linking the captured size of the planet in pixels and comparing this to its actual size in arcsec and found the error. Something must have happened in the optical train configuration while collecting the video from Dec 18, but I have no idea why as I capture the same way every time (or so I thought) ...

 

I have gone through a selection of the other images and they seem fine to me, below is an updated version with the correct size (and an extra image from Jan 31), apologies for the mistake ohlord.gif ohmy.gif .

Very nice image! Diameter of Mars changes quite obviously! May I ask what telescope did you use?

Aah, sorry about that. I took these using my Celestron Evolution with a C9.25" SCT, 2.5x PowerMate and ASI224MC camera.

Great sequence, Andrew!  To have almost a whole year of Mars images is really impressive.

Thanks, Tulloch. I think it's really great imaging result with C925 :)

That's excellent, Andrew.

Imagine if Paul Sunspot did that, it would look like an orange snowstorm or something!
