Like FWHM, I find that people get overly concerned about this. Being oversampled will have small S/N hit in terms of sampling. However- hasn't everyone claimed just how low noise CMOS sensors are? Now there is a question? I do not understand. The …

No... you are not losing anything. Somewhat of an arcane bit of math. -the Blockhead

I think this is the nature of the Amazon edge servers. Once more people start watching them- they will live on more servers and will be delivered more effectively to widely separated locations. (I am assuming you are having issues watching new video…

Yes.On the members page I post videos as I create them...but they might not be sequential within a given collection/course. Kinda multi-tasking. You can see I have uploaded two new videos since we last corresponded. -the Blockhead

Oh... I think you are talking about my latest videos on narrowband processing.I made an announcement to say I am creating these videos in realtime and will probably make a separate course for them. However Horizons subscribers are privy to watch the…

There are a couple of reasons- but one is that is has a handful of methods that are not all compatible with WBPP. You implicitly desire the automatic method of hot pixel removal. I do agree, it would be a convenience... but this is one I didn't feel…

What video are you referring to?(I have a few videos Victor! Include a link to your question!) -the Blockhead
-
Yes... that would definitely do it. You need to "oversubtract" and just allow only the HII regions. Remember... screening will always result in a bright pixel taken from both images... EXCEPT if one image has small (or black) values. That is the key…

In general you are correct. Optimizing a dark to better match light frames that have variations in temperature is a good move. However, it comes with so many caveats. The main takeaway from my lessons is that the use of dark optimization comes with …

Remove red is the answer- but the issue is probably more fundamental. Why do you have excess red?-the Blockhead

Yep.It says you made an instance... but did not light up a method.-the Blockhead

Hi Harry, I just want to point out I think you are asserting that a published value "different from THE telescope focal length" is different than what Image Solver calculates. However, if the calculation is valid and there are no issues... the calcu…

Perfectly expected. I would be impressed if you could tell the difference when zoomed out.But the question is a ratio... There would be a benefit is S/N in including the poor frames with respect to faint nebulosity. That is the game. 0.4 pixels for …

(You could just run on the registered data with ImageIntegration.. you do not need to run WBPP again if you know what I mean.)-the Blockhead

And this is with 1.8? (You can see how fuzziness is being rejected which is good.)-the Blockhead
-
The output still includes the non-cropped masterlight correct?This will have the rejection map.-the Blockhead

Winsorized Sigma Clipping with 1.8 as the High rejection value.Show the rejection image as well. -the Blockhead

You forgot to indicate something important.What were your rejection settings? Quoting from myself above... "why aren't you letting rejection take care of the bloated bits and still benefit from using these weighted frames which will help with the S/…

The forcing is only for the input (if I understand the question). When you look at the log you are looking at the results of a successful (calculated) plate solution. This is the output and indeed it will show you the new actual focal length as deri…

Hi Matthias, Sorry, I need more information.Are you talking about ZIP files?Are this ZIP files from my site? (can you show me an example?)Can you show a screenshot of it not having "Extract all" ?This issue is independent of PixInsight. (You do not …
