First for OSC... the sensor has a filter in front of each pixel. (A pixel is the smallest sensing area/region on the surface). So your 3kx3k sensor has 9 million pixels total. But you only have 2.25 million pixels with Red filters. 2.25 million with…

I understand the marketing. For example.... read this post (you can look at the entire thread):https://www.cloudynights.com/topic/855035-antila-triband-rgb-ultra-filter/?p=12377145 Just look at the bandpass graphs for this filter. This filter will a…

Yes, WBPP already basically does this for you. It will automatically create masters for each different exposure time (unless you increase the post calibration exposure telerance). So all you need to do is specify a registration reference frame manua…

The Triband filter, if I recall the bandpasses, cuts out a lot of the light that galaxies emit since they are continuum sources. Your filter will be better for nebula in general. I do not have a tutorial to work with data like this because, for gala…

Hi Joseph, Could you do me a favor and watch the video I put together on Astonomical Image Processing? https://www.adamblockstudios.com/articles/wbpp-astronomical-image-calibration I think you are asking about darks for the flat field images and dar…

Also... I think something you might be missing is that when you work with a color image you are actually working with THREE images simultaneously. It is so easy to think it is a single image. It isn't.'-the BLockhead

You need to specify "no change occurs" for which channel?Did you see my video? At 14:55 I explicitly show and explain. You are doing the right thing...but I am saying you will not see a change by looking at the RGB/K *channel* .There are FOUR channe…

Yes, I explain this effect. When you transfer the STF of a color image- the Lightness (RGB/K) values will not change. In the HT tool if you click on the any of the color channels you will see the change in parameters just like in my video. Again, th…

Would you by chance be doing this with an unlinked color image?-the Blockhead

Sorry, I am not certain I am following your question.You seem to be referring to the asteroid trails in your data.They are partially (but not entirely) rejected. The pre-processing with "default" settings may not give you the best results. Did you f…

Good... *sigh* This is what happens when updating videos.It gets...complicated! -The Blockhead

I fixed the issue..Step 9 was referring to the OLD video!! I have now updated Step 9 with the current ImageIntegration Lesson!!https://www.adamblockstudios.com/articles/fastrack_2025_image_integration -the Blockhead

Exactly... you always learn A LOT more by looking at the data. -the Blockhead

Yes, potentially. I addressed one way to do this in the recent video I uploaded.Once you have registered the masters produced by each- you can stack them and let ImageIntegration do the weighting. (You will need to make a copy of each image for a to…

Oh my!Now I see...What everyone is seeing is the OLD ImageIntegration video!That is not helpful at all. I will fix this as soon as possible.At the end of Step 8 I explicitly say these two files are to be used in ImageIntegration! .... Thank you for…

Wait..that is all you should see is the Drizzle files when you press the button. You would have already loaded the XISF files. Can you point to a timestamp in my video where I do something that you cannot? I still think there is a misunderstanding.…
-
You can. There is a different way. You can use SubFrameSelector. I also have a series of videos that explain this method as well. However, as I explain in some videos, I think that people have a false sense of "security" when utilizing this methodol…

Hmm... a couple of comments. In my Fundamentals course (soon to be reorganized)- I explain what constitutes poorer frames.Differences in background does not mean a poor image (necessarily). None perfect round stars... is not necessarily a problem if…

HI Sam, To load the XDRZ files you need to press the special button in ImageIntegration ("Add Drizzle Files").When you press this button you will NOT see any XISF files. Can you please verify this is what you did?When you say you cannot load... I a…
