Mars image from today dawn

LT_Ng · #1 12-08-2005, 06:50 PM

Hi Folks,

My 1st time to post planetary image in this forum.

Havn't imaged planets for nearly half of a year. Below is my 1st Mars image taken at today dawn through a 12.5" F5 Newtonian + 3x + 2x barlows + Baader IR blocking filter + ToUcam, 1285 frames stacked and quick processed with Registax + PS.
Final image not so stunning as the red planet is still very small in angular size now and the air was not steady enough, seeing: 3-4/10 & transparency: 5/10 . Moreover, wanted to start imaging as quick as possible before the sky turning bright, and so, not have too much time to check focus. Maybe the focus of this image was a little out.

Anyway, hope you would still like it, and any comment is welcome.

Thats fantastic considering Mars is still some distance away

Hi William. Great to see you out getting some imaging done. Excellent shot.

Maybe I'll get my lazy bones out of bed early enough one morning to give it a try.

Great shot, nice little polar cap on top.

William,

WOW!!! That is excellent! and you say it is not so stunning.

I can't wait to see what you call stunning.

You should see what William can do with a mediocre avie of Saturn Ken. The mans got PS skills I can only dream of.

Now that I have PS I better get practicing!

Excellent image! well done, what happened to the colour? it seems a bit blue to me...

LT_Ng · #14 13-08-2005, 10:37 AM

Some said my image is too greenish, and you said it too bluish. I think I have to re-calibrate my LCD mon.

Thanks for your comment.

No, the seeing when I took this image was not so good. Mars was dancing and kept changing its size and focus on the screen.

But I was still happy for getting this image under such a seeing condition.

Maybe it was the Toohey's Blue I was a drink'n last night, love the detail in that image though, colour could be easily fixed in PS

maybe I need to run some curves & hue/satuation on my eyeballs

Any reason you used an IR filter?

Paul,

Thanks for your kind words.

Actually, I am weak on image processing, and my PS skills are at a beginner level. There are many people like Bird here being PS experts in fact. So, I do want to meet more people in Australia to have experience sharing on image processing so that we can learn something from each other. This is one of the focus for my last time visit to Brisbane, and I am very happy to meet you. I have learnt from you how to use ToUcam for autoguiding.

Thanks Paul.

No, not you but me to run those curves & hue/satuation on my eyeballs.

I am strong in contrast sensation but very poor in colour sensation. A defect to my eyes actually.

I don't know why an IR cutting filter is necessary for imaging Mars actually. Most experienced imagers have told me to do so and I follow their opinion. Maybe Mars emits/reflects much IR than other planets.

Just that I think like the LPI the ToUcam has one built in, correct me if I'm wrong.
