M33 From Headcorn

[Whitters]

Chris, The A set and the B set need to be processed seperately, then combine the results of each. Then the image has to be flipped as 0,0 is in a different corner on the imaging software to that on your processing software.

Hi Paul,

Did it right this time.  I used an application I've been dying to use for some time to do the following.

Firstly these images were a stack of ten from the (a) set using Stella Magic.  

Then I put them into PixInsight for a Histogram and SGBNR Gaussian filter (astronomy specific, see http://pleiades-astrophoto.com ) and ended up with the following: -

without SNGBR filter



with SNGBR filter



I must admit the original FITS we're an educaiton because the histogram of each image was very thin but it seemed to contain quite a lot of dynamic range.

I tried not to burn out the stars.  Hope you like them.

Bye

Top image looks better to me.

[Whitters]

That's more like it. I prefer the top image too the star images are smaller and it is sharper. If you want I can send you the callibration files, but there are rather a lot of them >150 files. But they will remove the verticle bias and a lot of the grainy noise.

Greg has had a go too, here is his image, again Greg did not have the callibration files.

Na that's ok, I'll collect some more of my own soon, hopefully.  Nice pics though, I'm positive with a little more processing these FITS will give an excellent result.

Something for you to do on cloudy nights eh!  Oh thats now....

Hi Paul,

I finished off a second attempt with your M33, details as follows.  

Stacked in API4WIN, unsharp mask, levels applied in PS7, gausian blur in PixInsight.

You really should show your M33 at the next meeting.




P.S. If you ever feel like giving away the camera, I'll have it.
