Re: what is SNR impact of 2x2 binning of bayered images?

Hi Ivo, Very good. I will switch to your new version 1.5.366 of Startools, and stick with dcraw -h superpixel debayering before DSS and then Startools! I have info here for DSS-4.1.0. Based on the announcement for DSS-4.2.0, I don't believe anything has changed with regard to white balance for raw f...

Re: what is SNR impact of 2x2 binning of bayered images?

Happy-kat, It looks like DSS 4.2.0 still does white balancing when processing .CR2 files, either Daylight or Camera settings. See the DSS announcement here -- https://stargazerslounge.com/topic/337878-deepskystacker-420-is-now-available/?tab=comments#comment-3676948 So I'll still be using dcraw firs...

Re: what is SNR impact of 2x2 binning of bayered images?

Hi Ivo, Thanks for the explanation. I wonder if when I use my Path B) dcraw -h to create superpixels with values (R, (G1+G2)/2, B), and feed that into StarTools and choosing "Data was bayered and not white balanced", how the SNR compares to my Path A) dcraw -q 0 to do bilinear debayering, then Star ...

what is SNR impact of 2x2 binning of bayered images?

Hi, I use a Canon T6 DSLR, and then follow either path A or path B depending on how big my target is. Path A for smaller targets 1. convert all .CR2 to full resolution .tiff with dcraw bilinear debayering 2. Deep Sky Stacker 3. Star Tools without any binning. Crop smaller area of interest. Path B fo...

Re: Color Module questions

A very minor complaint is that clicking on the individual help setting description icons does not show help text in the Develop module in either version. I'm running Windows 7 64 bit on an i3-540 processor with 4GB of RAM. Star Tools is the 64 bit version for both 1.3.5.289 and 1.4.340. Hmmm.... I ...

Re: Color Module questions

Hi Ivo, Thanks for your response! Here is the improved result with 1.4.340. https://www.flickr.com/photos/stevestargazer/46139955444/ In the Color Module, the AutoMask with Fat Stars gave me a much better color balance right away. Unfortunately I never saved the mask I used in the Color module in 1....

Color Module questions

Hi Ivo, I've been exploring different ways of processing some M31 images from my Bortle Class 7 skies with a DSLR, 300mm f4 lens, and a Astronomix CLS light pollution filter. pass 1 No DSS RGB Background Calibration, StarTools processing log in BLUE at bottom of post. Color is off, noise is comparit...

Re: DSS 4.1.1 - can white balance be disabled completely?

Thanks Ivo! I did take a cursory look at the DSS source code in RAWUtils.cpp (function LoadRawFile at line 879), and see that when it calls dcraw, it leaves out the -w and -a dcraw options if they are not specified in the DSS options. However, it DOES NOT feed dcraw the custom white balance of "-r 1...

DSS 4.1.1 - can white balance be disabled completely?

Hi, I'm aware that this is a Star Tools forum, not a DSS forum, but I'm hoping someone knows the answer to this. I recently upgraded to DSS 4.1.1, 64 bit. Now that DSS 4.1.1 has been out several months, I wondered if anyone knows if DSS 4.1.1 white balancing can be completely turned off if using .CR...

Re: Help Buttons not working in Development Modules

I spoke too soon. Started processing another image, Autodev, bin 4x4, crop, wipe (color correction), AutoDev (cancelled), the Develop (help question marks do nothing).
I have 4GB of memory. I'll just print out the help screens from the window 8.1 machine and move on.
