    Having just got my monochrome camera (QHY 294M Pro), I went out on the first clear nights I could and I got great data. Then I had to face learning the beast that is PixInsight. Thanks to you making this video, I've finished my first ever narrowband image, and my first ever image in PixInsight! I couldn't be happier with the result! Thank you so much!

    PSF is Point Spread Function. It describes the spread function of star light that should be a point source but in your image has spreaded over a certain area. Decon uses the PSF to reverse that spreading of light.

    @christoph4977 3 роки тому

    Again, superb video Cuiv. For anyone reading this, I have a suggestion, that you not accept the winsorized default settings. I found, that the default values, especially sigma high, very often clips way too much actual detail. I would suggest to always inspect the high rejection map and increase the sigma value, until you are not clipping nebulosity. For me, sigma high has the biggest impact and it just feels wrong rejecting actual detail. Sometimes I can get away with 4.0 other times I have to go as high as 6.5. Every image is different. So I will run the default setting, and if I am clipping too much, I will increase sigma high incrementally by 0.5 or 1.0 until I see no nebulosity being clipped and only satellite trails and noise.

    Cuiv, if you were really really lazy you would take up Star Tools. Nevertheless your tutorials are appreciated. I am sure you will have short-cuts in Pixinsight. I have set up all my Newtonian OTAs in my observatories like you do: Focuser pointing down.

    • @CuivTheLazyGeek
      @CuivTheLazyGeek  4 роки тому

      Hahaha, I think to each their own! I've tried out Startools again recently for a few hours while following some tutorials, and couldn't get results I can get in PixInsight. Lack of skill and just not used to it no doubt! But with the EZ Suite from Darkarchon in PixInsight, the post processing is pretty much click and wait, so it doesn't get much lazier than that! :-) if you have some time and the impetus, I'd be super interested to see what you would get from Startools with the raw data in the description, as well as steps followed! No obligation of course, I am truly curious!

    Nicely done... but I am super lazy... I just throw everything into deepsky stacker for the pre processing and then move the stacked images into pixinsight for post processing.
    Might make an interesting video.. pixinsight batch processing vs deep sky stacker. Does the extra effort of calibrating separately, then running through sub frame selector really pay off?

    • @CuivTheLazyGeek
      @CuivTheLazyGeek  4 роки тому

      Hahaha, I completely understand that James! I can answer in the affirmative, yes it makes a huge difference, unless you exclude frames manually. Frames through the smog, or with clouds that get included at the same weight as others introduce lower SNR and worse gradients to deal with (from having tested in the past). Good video idea, I'm taking notes :-)

    I followed your method on my own data of this same target, although using a OSC and a refractor. On inspection after the EZSoftstretch I noticed some halos around some of the brighter stars. Did the EZDeconvolution do that? Were your values too aggressive for my data or too little?

    • @CuivTheLazyGeek
      @CuivTheLazyGeek  4 роки тому +3

      I also have some small halos as well! If the stars are not well masked, deconvolution could cause artifacts a bit like that indeed - one way to avoid them is to widen the stars in the star mask some more. My solution is more simple: I choose not to care :-)

      Excellent question! Yes, I really dislike the parameters used for weighting in the WBPP script. SNR is particularly problematic as it tends to have a higher value the more LP smog or clouds are in my image. Stars is a much better criteria to me, as it gives a summary of the image. Poor focus? Fewer detected stars. Wind and elongated stars? Fewer detected stars. Light pollution or clouds? Fewer detected stars. It's a catch-all that I really like, but is not available in WBPP...
