1 hour time lapse animation of Pillar Prom from Oct 31st, and some partial disc images

Post by AJamesB »

Seeing wasn't that great, so I probably would have been better off using a lower power telecentric for the time lapse, but ya never know until ya try. Nice pillar/tower/castle/Big Ben prom (is there an official name for those like there is for hedge row proms?) visible though, as well as the current active spot regions. Gif is forward playing only.

Beautiful prominence and excellent processing. Lunt LS100Ha, you say? I must experiment with a slightly increased scale on my 90 mm setup.

Fantastic animation and prom James!
Are you using ImPPG for your deconvolution?
Despite what you wrote about the seeing and the telecentric power you used, I see no grain in your animation around the prom. What is your "magic" process? ;-)

Thanks! I used an asi294 (with a smaller range of interest) with a baader 4x telecentric.

Thank you. Rather than use ImPPG for deconvolution, I find that for me using the deconvolution in Pixinsight, with its combined and concurrent wavelet denoising, usually lets me get better detail with a lot less noise.

For the remaining noise, I have a few options and just use what works best for the specific scenario. Here, doing a batch process with selective noise reduction in lightroom is what worked best. Other times it can be topaz denoise AI, or using pixinsight with masks. Other times nothing works well across the entire series of images, and I just live with the noise, lol.

Using ImPPG's unsharp masking in adaptive mode could also help in this case. It allows you to selectively sharpen (in addition or instead of L-R) only the bright parts, or even slightly blur the dark ones (see the tutorial).

I've been surprised at times at what details I can pull. Even when I'm zoomed in enough to where I'm seeing pixelation effects, using the 1.5x or 3x drizzle in autostakkert works well at filling in detail that otherwise would be limited in its ability to be sharpend by pixelation artifacts.

Thanks a lot Filip!
I am using ImPPG for almost one year and had never used this way... I think I had not seen this tutorial before (or forgot it and did not read the adaptive section), so it will be precious in making a more advanced use. The fantastic example of James and that of others using PixInsight shows that this software has a lot potential, but apart the price, the time I would have to devote in learning it is also discouraging for the moment. I may try it when I will have more time. Until then I will give a try to ImPPG's unsharp masking.

It is a pity that ImPPG has not a command for equalizing the overall brightness of all frames to be used in an animation. It could complete it for preparing an animation. So far I have heard that only PixInSight does this, so when I have to do it manually it is hard long work. Nevertheless the alignment tool (when I realized it exists), together with the batch process saved my life for animations. :-)

All the best,
Alexandros

PS: Filip, I did not know or had forgotten that you are the father of ImPPG! I just saw somewhere GreatAttractor while going through the tutorial and realized that, so THANK YOU Sooooooo MUCH for making this software available to the atsro-photographer community!!!

Try Settings/Normalize brightness levels... (set to 10%-90%) — it helps somewhat in case the sky brightness changes between stacks (e.g. due to passing thin clouds), though it won't always remove the perceived flicker. I might work on that in the future.

Thanks Filip!
That would be great if you can add something in the batch processing menu, so that flickering can be removed in animations through normalization between frames to the median brightness value or a user defined value (%) between the min and max of all frames. I had tried the normalization you propose and have already in the settings, but did not help a lot in removing the flickering from animations. I was wondering if it is taken under consideration by the software during batch processing. Perhaps it is my fault and I cannot find the best way to do it.

If you can succeed that one day, then ImPPG would become the perfect and simplest tool (much simpler than any other option) for batch processing. Though it is already really precious for many of us in its current form!

Thanks once more,
Alexandros

It is, but as you say, it's not guaranteed to help in all cases.

I've also read that some people use deflicker filters from video-editing software with some success.

Hi Filip,

I've used GBDeflicker for this purpose. https://granitebaysoftware.com/Products/ProductGBD.aspx

It's not guaranteed to work in all cases, but often reduces flickering quite a bit.
viewtopic.php?t=33519&p=308793

It would be really nice to have something similar functionality integrated into ImPPG.

Arne
