Mars 1st March

Probably getting a bit carried away, but it's not often you can resize 2X & get the image to hold in this game ;-)

Plus a side by side Stellarium screenshot.

That's just amazing :) And you can clearly see the swirl structure of the ice cap, very cool! Thanks for the view.

A nice red mars. I like it.

Wow that's excellent! Is that white spot below centre, Olympus Mons?

I think it is great when Astro Photographer's get carried away. :thumbsup: Please keep the images coming. That is a brilliant photo of Mars.

[lepton3]

Another great image John. You really have this down pat.

Mike, Olympus Mons is a little further to the left. Doesn't look cloudy at the moment. The cloud in the centre is one of the Tharsis Mons, probably Ascraeus Mons. I like the fact you can just make out the lighter region of Alba Patera as well.

Of course you would know all of this if you had made a Mars Globe ;) !

Well, you might be the man to answer this question then Ivan. In all my images from this night, we have 2 slight bulges/bumps on the limb. Can't be an aligning/stacking or processing errors, as I've tried different ways of doing all three..

[iceman]

Nicely done John. I like the simulation view best ;)

Great image.

[venus]

Great imaging.

[asimov]

Looks over processed ;)

[lepton3]

I take it you are referring to the bumps at positions 6 o'clock and just after 2 o'clock. Hmm, hadn't noticed that until you point it out.

According to my Mars Mini Globe (TM) There are no elevated features at those positions. 6 o'clock is the top edge of Daedalia Planum. 2 o'clock is the left edge of Arabia Terra.

If I sqint, 2 o'clock could be clouds -- is the bump pronounced in the B channel?

6 o'clock doesn't look like clouds to me at all. It has me beat.

I wonder if anyone else has any suggestions?

-Ivan

[asimov]

Thanks Ivan. Yes I've done an RGB split & I've come to the same *suspected* conclusion as you on the 2' oclock - cloud. The other one, I have no explanation as yet.

Both are on all sets of data & I've tried aligning & stacking on different features to discount any anomalies there.

Intriguing!

Nice work Asi, a top effort for sure.

Cheers

that's a real beauty Asi - more very fine imagery. Regards Ray

Those are beautiful shots of Mars. I just put a post on the Beginners photo page about settings as I just purchased the DBK 21AU618.AS for my C11 and struggling with the settings to use, could you give me a guide please? Also what would you normally expect a single image too look like on the screen in IC Capture (not sure if I am over-exposing, etc). Any help would be greatly appreciated. I would be very happy if I can get something even distantly approaching what you have achieved.

Sweet shots master Asimov. Great level of detail without artifacts.

This is the worst Mars opposition, so it will be better and better until the great 2018 event.

[asimov]

Thanks Trevor.

Thanks Ray.

Try this, Peter > http://pdfcast.org/pdf/dbk618

Master Asimov!:lol: Hello Luigi & thanks:thumbsup:

[Matt Wastell]

Super!

[Saturn%5]

Very nice.

[asimov]

Thanks Matt, Graeme.

[John Hothersall]

Another impressive Mars with amazing detail, nice to see thew changes as Mars gets bigger over the weeks.

John.

[Clayton]

Nice going Asi:thumbsup:
Sorry I missed this earlier:question:

[asimov]

Well mate, you didn't miss it on the other 2 forums, so I'm not concerned!:P:lol:

Thanks though Rob! :thumbsup:

[asimov]

And Thank you John!

[asimov]

Sorry Peter (Helo) forgot all about that single frame, didn't I. Here it is. It's not from this lot of images however.

This is with the YUY2 + unspecified codec hence it's a colour image. It's also one of the good frames out of the AVI. There's plenty of nasty ones too.

[Helo]

Thanks for the image Asi and for the manual. I have a much better idea on the settings but not getting frames anything like as clear as yours. I get a lot of shimmering which i am thinking may be heat haze coming from the roof of ours and the neighbours house, does this sound reasonable? It looks like cloud going across and can't get a good focus (definitely no cloud though). I think I will have to do a late night in a week and see if that makes a difference. :shrug:

[asimov]

Hi Peter. Shooting over roofs can certainly have an effect yes. To find out, I'd be doing a series of tests early AM like you have already assumed. Could be just seeing though. I'm shooting over our house 11PM onwards (Mars) as well.
