Mars in IR + animation. Morning of Jan 18th

Quark (Trevor) · #1 18-01-2010, 04:12 PM

Hi All,

The seeing this morning for Mars was pretty crook with very strong gusty winds and little assistance from the jetstream, however, I was able to capture some IR 807+nm images that have some detail.

Have attached a labeled IR image. I am pleased that as bad as the seeing was, the inverted "V" extending north from Oxia Palus is fairly well defined and I have labeled the legs of the "V" which are named after rivers from the time when it was thought they may be canals.

Have also attached an animation of 4 IR images acquired at approx 30 min intervals that came up a lot better than I expected.

Hoping for an improvement in seeing for tomorrow morning.

Thanks for looking.
Regards
Trevor

You can see how it's seeing affected, but the IR still reveals heaps of detail.

Nice work Trev.

Cool animation Trev. Nice details.

Lovely images Trevor, even with the slight loss of resolution due to the poor seeing. The animation appears remarkably 3D compared to other planetary animations I have seen. Great work again, you astro-imaging trooper!

Cheers

Dennis

Great imagery. Even managed to get an upside down Australia in there,LOL. Hang on a minute, it's MARS,LOL

Great work and thanks for sharing.

Cheers

Thanks Duncan, orientation of the images is a personal thing, whatever looks best will do.

I always present my planetary images with South on top and West to the right as that is the IAU convention for planetary images.

Thanks Dennis, glad you liked the animation, it turned out better than I initially expected.

Nice work Trev.

Thanks Mike, the seeing this morning was quite reasonable for several hours a lot better than this imaging session. I have 24 avi's to process, RGB & IR and hope to post some descent images, maybe by late this afternoon.

Hi Trevor,

Awesome work, always a treat to stop by and see the latest from you. Well done.

Quick question, I see this is in IR. Does this mean that you are only letting through the IR wavelengths or filtering them out?

The reason I am asking is because I want to have a go at Mars but its very bright and I am not sure if an IR cut filter (such as a UV/IR) or skyglow filter would help bring out the details? Visually I can see the polar caps but not much surface other than RED?

Thanks

Chris

Excellent images and animation. Really like seeing work like this - so cool

The animation really shows up just how quickly Mars rotates. Something you don't pick up in visual observing.

Thanx

Great animation Trevor, it's a nice way of seeing Mars.

Alex.

Thanks Chris, I am only capturing in the IR part of the spectrum. My filter passes from 807nm and longer. I have attached the performance graph for my filter. Hope this helps.

Thanks Alex, yes I think animations of the planets add something.

Thanks Rob, the rotational period for Mars is 24hrs 37min's 22 sec's so to make a descent animation requires imaging sessions of several hours.

Thanks Alan, but I am about to post better ones from the morning of Jan 19th.

Very nice images - I especially like the animation

Thanks Trevor, that clears it up a lot.
