General / Re: Why does WBPP use ConvertToGrayscale?
« Last post by astro_nic on 2019 November 21 22:24:30 »
I should mention that past that stage, I do see ICC profile embeded: 'sRGB IEC1966-2.1', 3144 bytes. However, the final light image/master is shown as: Gray 1:3 light_binning_integration | m42_master_light_60s_BINNING.xisf. But I can't convert to to colour once the WBPP has completed.


**UPDATE: I've made a few attempts, but looks like I got it in RBG form this time, although the quality is not very good. I will continue looking into the WBPP options, as I'm unsure why there is/was such a discrepancy between certain runs.

However, if anyone could explain the ConvertToGrayscale function, I would be interested in the benefits of it while batch processing.

Hi Steve,

Great image!  Have you done a Deconvolution on the Lum and/or Ha, cos that will bring out faint detail.

General / Why does WBPP use ConvertToGrayscale?
« Last post by astro_nic on 2019 November 21 22:10:18 »
I've been trying out the new Weighted Batch Preprocessing, and so far the results have been nice. However, I've noticed during the process, it uses a ConvertToGrayscale process which prevents me from gathering any colours out of my integrated image. Along with the ConvertToGrayscale process, it's also performing StarDetector, and DynamicPSF during this stage of the script, I'm assuming it might be choosing a registered image to use?

What is causing the script to run ConvertToGrayscale, and why is it being converted. Does it have to do with finding a good registered image? Could anyone shed any more details on this process, and if I can use WBPP and still have my RBG from an unbinned image (BIN set to 1).

Sorry but I can't see any obvious problem in the video you have provided. Anyway, we cannot observe any problem related to cursor movement over images on any platform, not even on Windows, and not even on relatively slow machines (4th generation core i7 for example).

It's hard to visually see it via video and not in person, but I have made a new one that shows this bug extremely clearly. It was recorded in 60 fps and slowed down by 56%. I used a macro to record my mouse movement and the video was synced to the exact frame. It is clearly shown that the cursor in the frame above is lagging behind the other one once it reaches the image window, but it is able to catch up when it goes outside of it.

Having one of the tabs open in the top menu removes it completely for some reason. The cursor lag is also still present even when PixInsight isn't the active window.

i have GTX1050 on macosx that does the same thing. it seems to be triggered by videos which are being displayed on webpages in safari. when i close the tab, the cursor starts working properly again.

Unfortunately this doesn't fix the issue on my Windows 10 PC (GTX 1060).

Bug Reports / Pixinsight v. 1.8.8-1 RAW format gone
« Last post by jnarro on 2019 November 21 20:01:25 »
New version installed two days ago, worked perfectly, today I found that the DSLR RAW format in the Format Explorer is gone, so Pixinsight canĀ“t read my RAW images, an error window appeared, the Repository has a problem, so I uninstalled and installed a couple of times and the same result, so I proceeded to install an older version i.8 and the same window error about the system unable to find the Repository but the RAW option is there.
No window with new updates appear in this oldie one, so something must be wrong with my license.
Please help.

General / M76 Narrowband and LRGB Data
« Last post by sreilly on 2019 November 21 19:15:07 »
So I've got a ton, well a fair amount, of data on M76 with the following:

16 - 15 minute red
16 -15 minute green
23 -15 minute blue
71 - 15 minute luminance

42 -30 minute Ha
41 -30 minute S2
40 - 30 minute O3

I have followed Karyon's tutorial at https://www.lightvortexastronomy.com/tutorial-narrowband-hubble-palette.html and came up with the S2HaO3 as attached.

The LRGB of M76 is also attached. What I'm curious about is if the data can be combined to show more detail in the nebula. I'm as green as they come with narrowband processing and maybe M76 wasn't a good target but.....any suggestions? I mean this is 61 .5 hours of NB data and 31.5 hours of LRGB. What could be done with 93 hours of total data. Just for the record, these were imaged with an STL-11000 CCD through a 12.5" OGS RC telescope on an AP1200GTO mount.

Suggestions, links to tutorials, anything?

Thanks,

Steve

I have noticed the same behavior in my setup (little "slow" pan), I think since version 1.8.6. Do you have an Nvidia video card? (mine is a GTX 1060)

Greetings,

Enzo.

Yes I have an Nvidia card. It's also the GTX 1060. It's incredibly annoying, and the first time I encountered it I thought it was intentionally since it doesn't depend on how large the image is. The behaviour happens the moment you hover your cursor over the window, and gets removed if you have anything else on top of it.
