Best video I could find on this process after viewing several others. 😊

@alistairfrith7772 9 месяцев назад

Really clear description of the whole tool, this should help me use it with understanding of what I am doing, instead of blindly putting in magic numbers some bloke down the pub once told me.

@padraigfarrell7150 Год назад

Others have already rightly said, how great this tutorial is, thanks. Liked, subscribed and SAVED !!!

@PhilippeNoth Месяц назад

Very useful info, thanks Sasha. Due to cloudy nights in 🇨🇭, I have been imaging with a Seestar lately. While the device is amazing and produces surprisingly good subs, the background - gradient and edges - can be tricky to clean. Will try Normalize and the extended options.

@astrobri Год назад

Wow, Thank you so much. This is the most informative tutorial on DBE I have found. Like the rest of your videos I have come out knowing so much more. I will highly recommend your that everyone watches this and I hope after has the same learning experience as me …. Thank you again for your time and effort. Clear skies from Brian Nova Scotia.👍

@terrydanks Год назад

Another Nova Scotian here that found this extremely helpful.

@TheMje1963 Год назад

Awesome video, You have explained DBE better than anyone I have watch thus far :) Great Job

@MrPedalpaddle 11 месяцев назад

Very helpful, especially addressing the tools for vignetting

@croenan Год назад

Great video! Looking forward to watching more on your channel. Great explanations.

@georgebokovos Год назад

Very useful information and a great series on PixInsight, thank you and clear skies!

@bokvaj Год назад

/bow .. thank you for deep explanation of this tool. Never knew there is anything like circular/linear selection of points :)

@rickbria8420 Год назад

Thank you, very well done video. Organization and presentation were fantastic. Very helpful. I really appreciate your efforts.

@Claude_Astrophoto Год назад

Sorry, forot to say the most important thing : VERY interesting video and Yes, very helpful !!!!

@anata5127 Год назад

That last part is well described in Adam Block’s video. He showed more complex situations than yours.

@viewintospace Год назад

Yes he does - that is for sure ;-)

@janeclark1881 Год назад

Very helpful, thank you. 🙂

@jonathanpearceff Год назад

Great video and lots of useful information. I guess you can spend hours playing with the settings. One question, is it a good idea to run another DBE if the first didn’t remove the issue, or is it best to just do one run? How about a second run with different sample points? I am not talking about doing a division then subtraction. Thanks, and a good series of videos.

@viewintospace Год назад

Thanks! Sure, it can and should be done iteratively like stretching. So attacking for example first the vignetting and then a general gradient makes a lot of sense. If you approach each run as a individual task to remove a specific part and adjust the settings based on it, no harm can be done - it might even be much less destructive than trying with overly aggressive settings to remove everything at once.

@Calzune Год назад

What about doing DBE after doing it starless (unstretched)

@viewintospace Год назад

This is in fact how I do it. I do the star removal as the very first step in my workflow, and all other steps incl. DBE afterwards with the stars already removed. I believe the less complexity a picture has, the better DBE runs - and stars surely are an additional complexity.

@Calzune Год назад

@@viewintospace i agree! But are there any downsides doing it? If not, why does i never see this on youtube?😅

@viewintospace Год назад

@@Calzune I do not see any downsides. Even Russ writes in his instructions to STX: "Use StarXTerminator as early in the processing flow as possible, ideally right after integration, with the data still in a linear state". If you have not seen it in YT, wait until I do a tutorial about star management (in pipeline) and you will see it ;-)

@Claude_Astrophoto Год назад

I don't recall you saying it - what is the normal POINT qty we need ?

@viewintospace Год назад

I assume you mean SAMPLE qty. And the answer is 42 ;-) Again, there are no absolut answers and no magic numbers. As a rule of thump, the more complex the background issues are, the more samples you need to set so that DBE can calculate them out. So don't count - just put samples at every place where you feel it makes sense for the process to have this information.

@Claude_Astrophoto Год назад

@@viewintospace Yes that was the question !!!! Thanks ... keep the good work - I really appreciate what you are doing.

@Claude_Astrophoto Год назад

a good one to check : ExtractWaveletLayers - i saw a video that the guy use this to sharpen image.
