M-13 re-processed

[daryl_lincoln]

I posted a image in another post but have re-processed the data and wanted so show the difference.

For people who are new to imaging even in what you think are bad images there is hope in processing

My 1st image (Top) re-processed (Bottom)

Fabulous!! That's the diamante cluster I know well, well captured!

Definitely an improvement there, well done. I think you can get even more out of it if you avoid making the background totally black. Best to process the image so the final result has a dark background, but not totally black.

Thanks pll

I find that a black background is my only option as i have bad LP and the red channel is too red. If i remove the red the other colours suffer and the background looks strange

yep, heck of an improvement in that.

Massive difference there, well done on the re-process. I can clearly see the 'propeller' in the bottom left quadrant of the cluster.

Very nice reprocess. Just as a heads up there is a good article about processing globular clusters in this months Astronomy Now by Nik Szymanek.

Well done Daryl, just goes to show that processing is half the battle!

I think there is more available there though, if you dont mind, may I have a go at the data?

If so Free File Hosting Made Simple - MediaFire is a good place to upload the unprocessed stack

Stacked images are here 1st time i have done this so hope it works

Feel free to use them but dont pass them off as your own on this or any website as it a good way of learning for both you and for me

post your images back in this post so i can see either good or bad

Hi Daryl

I couldnt improve on your image. Found it really hard to balance the colours, as I am unused to mono cameras (only just recently purchased one myself).

You definitely need to get better focus to improve things though

Have you tried a Bahtinov mask?

[daryl_lincoln]

Hi image with a meade DSI-II colour. I use the focus function on Meade's Evisage software which i think is great.

This image was taken more as a test image for my new roll on/off shed :-) to check polar allignment and guiding but always worth processing any images you get.

Hi Daryl

I had a quick go and like the background a bit lighter

As said I think the focus is a bit soft

good luck with the new shed

Nice...processing is more than half the battle sometimes I think.

[daryl_lincoln]

thanks harry

As you can see in ur image the battle i have with the red part of the image. This is the reason i prefer to have a darker background, this does help to correct this problem with colour uneveness

Hi Daryl,

What did you do to get such a big difference in your re-processing of M13 ?

[daryl_lincoln]

Hi Paul

The main differance was being alot more selective on the images i stacked but also different settings in ESA fits lab for photoshop (controls pixel math) then just playing with different levels and bits

Good guide to fits editing here FITS Liberator Tutorial

Cheers Daryl, have added it to my good advice stash. Paul
