DSS - images are just B/W

[lukebl]

Hi,

Can anyone tell me what I'm doing wrong with DeepSkyStacker?

I've loaded my RAW files, and DSS insists that the image depth is GREY, so that the resultant stacked image is in Black and White when I know that the originals are in colour.

Am I missing something?

All RAW files are grey, you have to tell it to debayer the color information (RAW/FITs DDP Settings). Which camera ar your RAW files coming from?

Luke, the resulting image that DSS displays always looks like it has no colour. On the saturation tab in DSS you have to set between 20 and 25% to get DSS to display the colours.

I don't use those adjustments though as I find them to be rather insensitive.

I'm using a Canon 400D. Can't work out what I should set the RAW/FITs DDP Settings.

The final image is definitely grey, and no amount of tweaking of the saturation will change that. Didn't seem to be a problem with a McNaught Comet image I did the other day, but last night's deep sky targets just come out B/W after stacking.

I have played around with the original RAW images in Photoshop and the colours are fine there. Don't use DSS all that often, you see.

When you click on the stack or register options, you should see a recommended option, use the values defined in there for the debayer. Subs shorter than 5 minutes generally take the Bilinear Interpolation, longer than that and DSS suggests using AHD.

That doesn't seem to make any difference to the colour depth.

This is what I mean:

Shouldn't the depth say RGB or Color or something?

Nope, that's exactly what mine shows in the file list using a 450d. Don't worry about it, it's cos they are RAW files. Now, getting colour in globs... that's something I'm struggling with too..

Ahh. it's probably OK then. It's just that if I open up a RAW image in Photoshop and really crank up the saturation, I can get the blues and golds like this single 9 minute exposure:

As soon as I put the images in DSS, the colour vanishes. I'm thinking, if I can get a single image to look like this, then a stacked one ought to look pretty good. (Incidentally, call me a philistine, but all globulars look the same to me which is why I don't normally bother with them!)

I have to agree with you there... I don't know... I'll take a look at one of my RAW's from M3 the other week.

Here's another pic to show my problem.

The left half is a small extract from a single RAW image - nice colour and load of stars. The right half is the product of three images of the same object stacked in DSS (I only did three as I was just testing my new guiding setup) - B/W and fewer stars.

What on earth am I doing wrong?

[jgs001]

Luke, is that second image straight from DSS, or after stretching and processing ?

That's straight from DSS, but no amount of stretching and processing appears to change a monochrome image

The DSS image looks like it is a colour image on my monitor - just very under-saturated colours.

I Would tend to agree as star colour could be dragged out of the RHS of the "test" image with a bit os tweaking of the Saturation in CS....
