No need for Photoshop, PixInsight or Star Tools. 5 to 1.įor the levels step, it is best to take fotos of a white star like Sirius or Vega at different settings, store these as presets in Gimp and apply the proper preset for the image you want to process. Substract the duplicated layer at 70% from the levels layer and merge down.įinal step, apply a selective guassian blur between. It will be filled with the background color. Next, select a rectangle of your region of intrest and crop your image, then select all the area on the cropped duplicated layer and delete it. Now with the color picker select the darkest area of the despeckled layer (any of the corners) and make that the background color. Top and bottom sliders all the way to the right, middle slider all the way to the left. On the duplicated layer, despeckle with none of the options turned on. Select the whitest star in your image at the center, with the white picker, and move it away from the center pixel by pixel until you get the contrast you prefer. Select the white picker icon (furthest too the right, lower right side of the levels menu) But if you have a version of GIMP that works directly with 16- or 32-bit images, might as well use that directly. I've often done some slight edits in RawTherapee before bringing the image into GIMP, but sometimes not.

RawTherappe is a free and open source RAW editor - same kind of program as Lightroom, basically - that also works pretty well with the TIFFs that DSS outputs. Instead, I've usually used RawTherapee as an intermediary between DSS and GIMP.
I haven't used GIMP with TIFF files my OS doesn't have Gimp 2.9 yet.

I'd try a web search for "GIMP plugin install ". I think the steps for installing GIMP plugins vary by operating system. For the wavelet plugin do you just put it's folder in the GIMP folder?

I can't afford PS or other software so I thought I would try GIMP on my DLSR pics from DSS. I wanted to go back and try restacking with DSS and using GIMP. I got a pretty good stack from Nebulosity of North American Nebula with my D5100. I uninstalled the 2.8 and installed the 2.9 and it works fine so far. I tried splitting the RGB but only got blue for some reason. Still got B&W image or barely no color at all. Under "filter" "Enhance" "Wavelet Noise reducer" and try a starting value of 0.001 and try different values from there.

Version 2.9 gimp doesn't have a wavelet denoise plugin yet to reduce background noise, but if you download KRITA (Windows, Mac or LINUX) you can use its filter for this" Canbe very handy if using narrowband on a DSLR as for instance you can decompose a colour Ha image and delete the green and blue layers so you only work with the red layer (which will be shown as B&W) If working with colour you can also seperate into each RGB layer and do teh above steps to have better control over each colour - use : "Colours" "Components" "Decompose".
If the image has a brownish tinge to background click the Black Pipette looking thing under that leftmost slider called "pick black point for selected channel" then goto view zoom 400% then move to an area of the image with no stars (just fuzzy noise) and click it and it will make that brownish background blacker - hit undo if you think it goes too far. Possibly (and most likely) repeat step 5 again to see if you can get more detailĨ. Repeat step 5 but this time instead of the middle arrow slide the left arrow to the very start of the left hand side of the histogram which will make background darker.ħ.
Slide middle triangle over to the left until the image just starts showing detail (don't worry if background is getting lighter" - hit okĦ. you can use other methods that can work better bit this will get you 90% of the way to a great image.ĥ. GIMP - OK this is a very simplistic way of doing things to get you started. Choose TIFF 32bit rational for file type (or you can opt for 16bit but I see no point) - AND MAKE SURE that you DONT tick the "apply adjustments to image" because you want to modify using GIMP not DSS.
Once complete don't edit anything, just go to the Processing tab and click "save picture to file".Ģ. Get it from here as it wasn't linked on the website:ġ. Ok GIMP 2.9.8 has been released and you need to use this to edit 16bit/32bit.
