CCDsharp with DSLR images?

[michaelmorris]

I've heard several people recommend using CCDsharp software for deconvolution of DSO images. My set up for DSO imaging is a Canon 1000D DSLR. I do my initial processing (flats, darks stacking etc) in Deepskystacker software. Try as I might, I can't work out how to convert the colour output from DSS into anything that CCDsharp can use.

Help!

I don't know if you ever resolved this but I'm tackling the same issue right now and got my image into ccdsharp from DSS via PixInsight LE by extracted the L layer and saving it as an unsigned 16bit fits (wihout the profile box ticked).

Sam thanks for the reply. No, I haven't yet got this resolved.

Thanks for your suggestion, I'll give it a try.

CCD sharp needs 16bit fits in integer (as opposed to floating point) format. May well need to be mono.

Sam - thats great - I hadn't thought of that for those that don't have a fits proggy - good idea!

It does need to be mono for CCDSharp - so maybe the best way is to desaturate your image first, and then make a blend of deconvolved data and the desaturated data - use this as a luminance layer, with the original colour data - it should sharpen things up considerably,

Good luck!

Cheers,

In PixInsight LE I split out just the Luminance layer, deconvolve that layer in ccdsharp then open that result in PixInsight LE and replace the original luminance layer with the deconvolved one - seems to give a pretty good result.

All my images are colour. What is the simplest way to split a colour 16 bit TIFF file into three (RGB) 16 bit mono FIT images?

[RichieJarvis]

Cut n paste each channel in your image editing proggy into a greyscale image.

Came across this old thread trying to find out how to get an image from Deep Sky Stacker into CCDSharp.

PixInsight LE no longer seems to be available. The free Iris seems to work for me:

Iris software

Load the image from DSS into Iris, choose "Digital Photo / 48-bits to 16-bits", then save as a FITS file.

[Luke]

Sorry, it doesn't look like Iris to CCDSharp works after all as described above.

Although the FITS file will load into CCDSharp, on closer inspection it looks clipped and missing data!

On the plus, Iris can do deconvolution directly.
