The 32bit file is not corrupt, I have it open in Startools right now.

If you just right-click and download the file from the link here then it doesn't download properly, if you click the link then click the download button from the Dropbox page it works.

There does seem to be less noise in the 32bit file.
This is just running it through Startools.
Wipe > Develop > HDR > Contrast > wavelet sharpen > noise reduction

I'm sure with a bit more love you could get it looking great

Obviously, that's how I got the 16bit file
I meant it may have been corrupted during the download, doesnt happen nearly as offten as it used to, but still does occasionally.

Again you upload version 16 bits. But at this time the red channel is with better and clear information. It would be a good photo, but the excessive drift kill it. You loose details... and ... the photo.

I did a convertion to 32 bits and I worked with HDR curve. The red channel has much data about clouds around M 8. As I said... it would be a good photo ... sorry, it would be !

Red channel attached.

Fair enough, we live in an imperfect world

Photoshop thinks it's a 32 bit per channel image...?

Sadly
Back in my dial-up days, corrupted downloads were the norm.
The only broadband I have access to is wireless(Vivid) which, while not as error prone as dial-up was, still has its moments
I thought about attempting the DL again but it was late and I didn't have the patience.

I didn't understand the question. But the file from 6D to download is 16 bits, not 32 bits original from DSS. Probably converted with DSS.

You get better result if you load the Autosave.tif - 32 bits from DSS - in Photoshop, and convet it to 16 bits.

Photoshop CS3 with Local Adaptation option where you have an HDR curve to enhance the photo.

Photoshop CS6 is more complex. You have option to work with many sliders that act in specific area in the curve. The result is better than CS3, but I didn't like to work with it. I prefer CS3.

Sorry my fault for using a question mark in a confusing way

I just realised we're talking about 2 different images, sorry! I was talking about the 32bit 600D image D'oh

Played with the curve on my previous attempt (original 16bit file) to try and increase contrast but I don't like what it has done to the stars and it has blown the core of M8.
Would now need to play with masks and layers in PS, but I don't have time for that.
Again, all processing in AstroArt, resized in PS.

yes, pluto, I am talking about the new photo from 6D. I didn't download the 32 bits version from 600D.

Quote:
Yes the Autosave is 32bit but you can also choose to save a TIF, or FITS, in 32bit which is what the OP did.
That is true. But, warning, when you use a version saved by DSS you can do it with or without DSS adjustment features. I prefer to use the original Autosave.tif.

Thank you Yugant, Bob, Simon, Hugh, Jorge for taking the time to process these. Truly remarkable compared to the original i've uploaded

Jorge you're correct there was a little trailing in my 6D version, unfortunately. I can upload the Autosave.tif file if you wish?
