Original images:

Images M14-000.FTS to M14-004.FTS are 5 shots of M14 cluster. You can see that the quality is not high and there are lots of hot pixels - they were taken with my first camera, a low end PICTOR 208XT. Also, there is not too much detail in the images.

See one of the images:

You can see that there are small shifts from one image to another. Don't care, CADET will automatically register the images for you during the calibration operation.

Dark frames:

Images DARK-000.FTS to DARK-002.FTS are dark frames for calibration.

See one of the dark frames:

Flat fields:

Images FLAT-000.FTS to FLAT-002.FTS are flat fields for calibration.

See one of the flat fields. Background and range has been adjusted so that vigneting and dust are evident:

Dark frames for flat fields:

Images DFLAT-~1.FTS to DFLAT-~3.FTS are dark frames for the flat fields.

I will not include any of the images as they are very similar to the previous dark frame image - just to improve the speed this page is loaded.

Calibrated image:

Image M14.FTS is the result of calibration with CADET using above images. Try it.

See the result:

Dr. Okano's Digital Development Process on calibrated image:

Image M14DDP.FTS is the result of aplying DDP process to M14.FTS, using a hard Butterworth filter. It looks like this:

Deconvolved image:

Image M14DEC.FTS is the result of deconvolving M14.FTS using maximum entropy method. Chi square was set to 1.2 and Chi square tolerance was set to 0.1

Some 204 iterations were necessary. The ellapsed time was less than 3 minutes using a Pentium III at 450 Mhz.

See the final result:

Image M14DCDDP.FTS is the result of aplying DDP process to M14DEC.FTS, using a hard Butterworth filter. It looks like this:
