  • Hi Burno, Since you areworking with Narrowband data... please watch the video concerning the use of a Pedestal...  https://www.adamblockstudios.com/articles/wbpp-21-pedestal-usage-narrowband-imagery This is certainly something to check since it can…
    in WBPP Fails to work Comment by BlockHead July 2022
  • Yeah... I would only be guessing. I think the zero level background could very well be part of the issue.-the BLockhead
    in Star Detection for Generated Star Fields Comment by BlockHead July 2022
  • Hi Wade, I do not know. Based on your description I assume you disabled (put to "never") the PSF fits. This is the only parameter that I would think would control this behavior you are describing. -the Blockhead

  • Regarding the precision, John knows that I know the answer to that question.Whether that precision (here we really mean the photometry) matters to the average user is a different question. There was a reason I was an early adopter of NSG.-the Blockh…
    in NormalizedScaleGradientScript and WBPP Comment by BlockHead July 2022
  • Well... it is unlikely the globular cluster will completely go away. The rest of the frame looks perfectly normal. You likely have few enough star residuals that the GAME tool might just make the masking easier. My technique is really for the case y…
    in Comet processing using Star Exterminator Comment by BlockHead July 2022
  • Darn it... no, I was not aware.It appears I have a missing video file...and I no longer see it!I will need to re-record. I am not certain of everything I was doing...so it will take me a little bit. Thanks for letting me know. -the Blockhead

  • HI Mike, Did you use my residual masking idea/technique to reduce them?Residuals are a thing- but what you are left with is much better than the standard way by rejection only.  -the Blockhead

  • Ah... I see. Yes, that might do it too.Good job!-the Blockhead
    in Red Halos around some Stars Comment by BlockHead July 2022
  • Hi Mike, The transfer curve of LRBG Combination is something you will need to experiment with. The simplest answer is that your color data is fuzzier (stars have larger halos) than they do in the Luminance image. This could be because you sharpen th…

  • Hi Reggie, What you are describing is a situation where the sensor (or data) is not actually 16-bits...yet you are telling me it is! So I do not know an easy answer based on your description of the issue. -the Blockhead
    in Flat Frame Problem in PixInsight? Comment by BlockHead July 2022
  • I think in principle there isn't an issue and no special steps need to be taken. I would assume the calibration data (the darks) would need to be taken in the same way as the lights in order to get all of the noise sources to be the same. I am aware…
    in Integration of stacked images. Comment by BlockHead July 2022
  • Nothing wrong at all. All of this is relatively new and ultimately requires many people doing this to see how things go. Seems like you did your homework. -the Blockhead
    in NormalizedScaleGradientScript and WBPP Comment by BlockHead July 2022
  • Hi Matthew, I am curious... what did you conclude?I may need to make a more concrete statement on things in a more relevant way..somewhere.  -the Blockhead
    in NormalizedScaleGradientScript and WBPP Comment by BlockHead July 2022
  • Hi David, Yeah it appears you have out-of-focus stars and a bit of a collimation issue. Deconvolution will not help this.In StarAlignment under the Star Detection you can set compute PSFs to Never. I believe this will force to find stars based on ju…
    in distorted stars Comment by BlockHead July 2022
  • Hi Gary, This isn't the approach I would take. When you integrate 72 subframes in one panel and 40 in another (for a given filter) there will be a slight difference in signal to noise- but is likely will not be noticeable. The average of 40 frames w…
    in WBPP question about Mosaics Comment by BlockHead July 2022
  • Hi Brian, With regards to light pollution let's talk about the statement you said above that applies: " DBE takes care of gradients but seems to wipeout the background color that should be there in this image. " I think this is a very good point you…
    in Battling light pollution Comment by BlockHead July 2022
  • Hi Brian, A light polluted image is one that has a bright background with elevated sky counts. When the moon is in the sky, this is a form of light pollution. Many imagers have other issues in addition to the light pollution.So, if you have a good e…
    in Battling light pollution Comment by BlockHead July 2022
  • Hi Kevin, Yeah, I had to choose what kind of data would be my example for FastTrack Training- and most beginners start with OSC. If I had chosen the mono route- many people would have been turned off. I figure the mono imagers (such as yourself) get…
    in Thanks for the WBPP update videos Comment by BlockHead July 2022
  • You should definitely not be "scaling" (that is dark frame optimization if that is what you mean).You are right, it shouldn't be hard- BUT you need to be careful and PRECISE. You will likely need to start over and do *everything* just so. The game i…
    in Amp Glow Comment by BlockHead June 2022
  • Hi Steve, A couple of things.... 1. I show a method- one of many- in my Horizons NGC 6250 example: https://www.adamblockstudios.com/categories/ngc6250 2. There are different ways of handling the blending of this kind of information. One way, as I di…
