Mars in IR (Infinity camera)

Posted By Mike Wirths

Ok,

heres my Mars from this am, shot in IR passband (685nm) using my 18" Starmaster dob. This time I shot it in true 12 bit mode and processed it for the 1st time using Iris but I processed it in IP. Stack of 500. Resized 20% Seeing was 5-6/10 at times. Filter wheel is on its way!

cheers

Moretus in shadow

Posted By Mike Wirths

Hi all,

Well this ones not in the same league as Alans shot, but it does show it even deeper in shadow. I downsized it about 20% as it gaves more bite, the seeing was not coperating that night, still I think its the best shot from that evening. There seems to be strange small bumps (like small domes) visible on the crater floor, I wonder if they are volcanic in nature?

Mars in IR (Infinity camera)--again

Posted By Mike Wirths

Heres a preliminary processing I just did of Mars in 7/10 seeing (1st half way decent seeing in a while grin ) 40% resampled. Should get the filter wheel this week!

Mars in good seeing--Redone

Posted By Mike Wirths

Hi all,

Well the 1st time I posted this image was after imaging at 4:00 in the am so I was breaking the rule of processing while tired wink So heres my attempt to better use the good avis I got that morning, IMO the edge ring effect is less obtrusive and the overall detail is better... I think this is the one I'm happy with!
BTW if you look at the image 7:00 o clock on the terminator you can see a little "planetary pimple" this is Olympus Mons, almost a 3-D effect!

Fixed Mars edge effect?

Posted By Mike Wirths

Hi all,

I've been annoyed by the aethetics of the damn edge effect, last time I was out imaging I knew I had some good data due to 7/10 seeing but try as I might I could not process the final stack without getting that damn exaggerated line at the sunlit edge of Mars. I tried just interations of unsharp mask, LC deconv, and of course the usual wavelets, but I always ended up with the same effect.
Usually I use Images Plus but for a change I tried the wavelets in Registax 3 instead, they seem to ramp up with their effect a lot faster than in IP so this time I ended up with he desired sharpening but very little edge effect! I never liked the wavelets in Reg very much cause the interface was clunky I thought, but for Mars it did the trick for me!
The edge is still there faintly but since I believe this is a real feature I think its probably about as prominent as it should be.

thanks

Big Kepler splat!

Posted By Mike Wirths

Hi all,

Well seeing was pretty crappy tonight yet again so instead of trying in vain for high res shots I stuck in the 2.5 barlow and tried for lower res features such as ray patterns. This Kepler with a stack of about 120 through a red filter (I was testing a colour filter wheel).

Marius hills

Posted By Mike Wirths

This one overlaps with the Kepler shot you can see its rays off to the right of the image, there are lots of smaller domes with the Marius rille in the image as well.

Aristarchus/Schroeter in sunset

Posted By Mike Wirths

Hi all,

Imaged this one of my favorite areas of the moon in 4/10 seeing the other night, its very similar angle to one done by Alan but his was in the opposite light.

1st colour Mars shot

Posted By Mike Wirths

Hi all,

Tried out my new filter wheel for the 1st time last night, the normal 5X's barlow that I use was way to much for the seeing (which was 5/10) so I used a 2.5 which made for a very small image but it was a trail run. Filter set is a type I True tech. stacks of about 250 per RGB. Not sure if I like the colour balance but its a start. Hopefully today I get my 4X's powermate which will give a good balance of image scale. Scope was my 18" Starmaster. Camera Infinity 2-2, 36 fps.

comments critiques, ways to improve it? This is only a quick and dirty 1st version...
In the image you can see a lot of haze and dust on the sunlit limb probably kicked up by the dust storm.
