Thanks Adam! That's perfect, I was talking about the exactly elements you mentioned. And in this unprocessed image, you the format of the stars looks not very round to me. Any clue?
-
Thanks Adam, I attached the images, the luminance has a stronger stray light, but all channels have the stray light too. Well, seems to me I will still need to rely on Clone Stamp or Healing Brush in a starless image, and maybe use Photoshop with tw…

Thank you Adam, Any advice to avoid this issue in the capture? I am using a CDK 17 and a Moravian C3 camera in Obstech, with no rotator, so is not so easy to change camera position.

The problem is I have the same scattered light in L, R, G and B channels, so I don’t have a source to copy from, as you suggested in your video. I will send you an image soon, but basically is a scattered light in the corner of the image
-
Hi Adam, my scattered light is all over the LRGB channels. Is there any video considering this situation?
-
Perfect, I will take a look
-
Thanks Adam! And what about the capture of stars, when you already did a comet tracked capture? Any special advice? Or just capture the the RA/DEC of the comet, but tracking stars instead of the comet?

Ok, so if I get it right, HDRMT may be easier if you know all the tricks, and understand the results of each parameter. Otherwise, GHS may be a easier choice, after all you have the histogram to help you understanding what you are doing, and is more…

That’s a good question. Maybe I got to little Ha in the continuum subtraction (a 2x factor maybe could have be a better idea in this particular image), and then I pushed the red too much to compensate it. To summarize, I want the red, but I don’t wa…

Sorry, silly mistake. Hot Auto check is false. I must have forgot to check the box. Right?
-
Well, looking to both pictures, and measuring them, the version with less integrated frames and lower FWHM is still sharper, before and after BlurXterminator. Not a huge difference, but visible. Any clue of what I could be doing wrong? Or that’s the…

Yeah, I decided to run WBPP just to be on the safe side
-
No, this is auto settings. Winsorized Sigma Clipping 1.8 still processing
-
Oh, sure! Sorry
-
Ok, I will try it. As I selected autocrop, the rejection image does not appear automatically. Is it possible to show it?
-
The full integration was with default parameters. I did another integration with 0.3 minimum weight, PSF Signal Weight weighting scheme. In terms of FWHM after BlueXterminator, the results were quite the same of the one with default parameters. Wo…

Hi Adam! I did a test with 2 integrated frames of NGC 3521 (Luminance). One with 277 frames, and other with 142 frames with less than 2.4 FWHM. PSF Signal Weight on default. Captured with a CDK 17 and L550 mount, full frame Moravian C3, in Obstech, …
-
Ok! Any way to define a minimum weight per filter?
-
Well, I believe you, and to be honest I would hate to discard frames just because they are fuzzier than others. And that's true, many experienced astrophotographers with big aperture telescopes in dark sites do discard high FWHM frames. It puzzles m…

Hi Adam! What would you personally consider as reasonable in terms of FWHM in a frame? For instance,!would you still integrate frames of a galaxy with higher FWHM than 3” ?
