NGC6188 - The Dark Storm

[cventer]

Took this one 2 nights ago.

Amazing area. So much action. Reminds me of a massive storm front or even a sandstorm approaching.

Need to get some color data for this one

Image Data: 15 x 8 min Ha Bin 1 x 1
Camera: SBIG ST2000XM with CFW8A
Mount: Paramount MX
Scope: TakahashiFSQ106 at F5
Processing: Image Processed with CCDStack 2, Photoshop CS 5.5.

Chris,

This was the first region I shot with my FSQ. I have never been able to complete it. And, it looked pretty ordinary through the DSLR.

If this infernal weather, and workload ever ceases, this year might be my year.

Thanks for the inspiration.

Wow got to love your processing and focusing :) Very impressive.

Thanks very much

the FSQ is hands down the best Telescope I have bought. Cant wait to see your version.

Thanks. Focusing is done with Focusmax, but processing is all me....

Amazing detail and sharpness.

Great shot. One of my fav. :thumbsup:

That's a ripper Chris. One of your best.

I am amazed a 2mp camera can capture that.

Fantastic part of the sky. Well captured :thumbsup:

Thanks Greg. I am pleased how well the ST-2000XM still performs. I like the Pixel size of 7.4 microns and for a 7 year old camera its still sucking in some nice photons.

What I have started doing is up sampling all my images before processing using Mitchel algorithm that preserves flux. I then do deconvolution on this upscaled image and find I get much better deconvoltuon results on larger star profiles. Before displaying after final processing in Photoshop I then downsample again using Bicubic downsampling and the results is not too bad for a 2mb camera.

Thanks peter. Point your Honda at this area. I would love to see the results with STX and that scope.

Funny I do something quite similar Chris, which seems to work for short'ish focal lengths, I do kind of psudo multi strength decon really as having better image scale in the first place is far better but it only works ok on bright areas really

Great result by the way, lovely tonal range...this area was very good to me last year ;)

Very interesting Chris.

What program are you using when doing this?

I haven't heard of the Mitchel algorithim before. Is this in the program or is it a plug in of some sort?

Greg

I am using CCD Stack. In Edit->Transform->Resize->SpecifyScale

Choose Mitchel as interpolation Method and tick preserve flux.

I only do this becuase my images with current camera are undersampled. Once my STF-8300 arrives with much smaller pixels I doubt I will have to do this.

Very impressive and a quite appropriate name for the thread. Can't wait to see the colour.

Just love Ha data! :D

Finishing it in narrow or broadband ?:shrug:
