Short answer.... I don't know. I suspect my approach would be different in that I would like more control so I would use the ImageBlend script. However, I have not yet investigated these in depth. -the Blockhead

You are correct. There are two uses for a bias. 1. Calibrate Flats2. Scale/Optimize Darks Do not do #2 in general and don't do it without understanding the effects of doing so. Never optimize darks to calibrate Flats. With respect to #1- if you have…

64?That seems excessive. When you take multiple frames you are making multiple measurements. It really depends on how noisy your camera/sensor is. Today sensors are not *that* noisy. So you are really looking for good statistics in minimizing the no…

Well... the issue is some content is derived from other places at other times. It is tough when I re-record content to accommodate new features or methods...but some older videos remain because they are references. So here are some points: 1. I will…

Yeah...OK. Again, this is from memory. Please check the official forum..I am pretty sure I saw a note about this.-the Blockhead

Please search for this on the official Pixinsight forum.I believe I saw mention that this is a bug (and either was fixed or will be fixed... I do not know if you are up-to-date). I believe WBPP is actually doing everything correctly...but the warnin…

Yeah... you might need to post a series of screenshots... The previous step is DBE... 1. It is possible that you introduced bias..but I find that hard to believe.2. You forgot to reset your STF. Remember after DBE (and carrying through to SPCC) you…

So... I do not know.You have the same numbers... the numbers should come out the same.Computers obviously will not give you different answers for the same input. However, we need to definitely agree on something- because you kinda called me a liar. …

The graph you show looks OK to me. There is some scatter... but the fit is likely OK. Tell me more about the "blue tinge." 1. Did you choose an appropriate background neutralization area?2. Did you select the sensor AND the filters for the Sony stuf…

Good. Because that isn't how you would using grouping and I would going to suggest approaching the issue by looking for a different related grouping criterion. -the Blockhead

I think this is the third time I have seen the request. Yeah, ImageBlend is basically Photoshop pulled into Pixinsight a bit.People tend to forget... I used to be the go-to-guy for Photoshop info as well! lol So a course that highlights all of the t…

Yes.If the original values in the image were 0.96, 0.9, and 0.95 ...and after you perform an operation they all become "1"...that is white clipping. Same at the bottom end... where you make all values zeros. In some recent videos it is useful to c…

My opinion is- given enough time and all of that- OSC is fine. BUT- the issue that people do not understand is that OSC is imperfect in some subtle ways that require *more* attention and *more* time on the processing side of the equation. You learne…

Yes, this is because the dark frame method of CC is part of the image calibration process. Literally ImageCalibration... which is why it is just _c . -the Blockhead

Hi Zak, There isn't a difference.... the workflow is the same.You just use one filter in DBExtract instead of two. In addition, you just do HOO.Both of these topics I demonstrate.Does this make sense? -the Blockhead

John, On the oops page... below the video you will find links that have the original video:https://www.adamblockstudios.com/articles/ooops-messed-up-kinda-like-it -the Blochead

By the way... the brownish red is actually a better color rendition. The Ha actually fills this field... my Oops version, for reasons I explain, loses color. -the Blockhead

Yes there is.... You will need to watch the "Ooops" section for an explanation. The second image you like... I kinda like to... but it is not "standard" and so I cannot spell it out as a normal workflow. However, with regards to the instructions on…

I know more today then I did back then. In NB FastTrack I demonstrate that Linear Fit will do a majority of the work and NB Normalization (with its additional adjustments) does the rest. I do believe it is the best way to proceed to ensure optimal r…

I guess I disagree. It isn't a step. It depends on the data and what you are doing. I do certainly use it and show using it many times in the demonstration videos. There may be a pattern- but I think it is more nuanced then any simple set of "rules"…
