Just a quick enquiry ... was strolling the lunar surface on Iroc and bumped into this area of florescence on the lunar surface.
Any thoughts anyone? (Co-ordinates at bottom of screenshot if you want to get better definition from original website).
Was struggling to see clear heavy impact crater that would account for the wide spread of surface debris?
Didn't think it was image flare - not expert on that so could be wrong - but noticed on RHS there appears to be traces of surface debris scatter?
It almost seems like someone threw a very low velocity ‘flour bomb’ at the surface of the Moon?🤨
Have there been mineral studies done on these areas of exceptional lunar florescence? ... I tapped the phrase into SGL’s Search ... but surprisingly it came up with ‘no results’??
Hey everyone. Have previously stumbled across this forum when searching for answers to questions, have finally made an account.
Last night I shot the moon for a couple of hours. I took around 10x3 minute videos and captured a little over 80,000 frames. My aim was to then create a lunar mosaic image but I have never done this before, and my technical ability seems to be adding to the confusion.
So to give some context, I used an ASI120MCS planetary camera through an 8" Skywatcher Skyliner 200p dobsonian.
I have read that ideally you would use a tracking mount to record sections of the moon at a time, however I sadly don't have that luxury.
I instead let the moon drift across the field of view and I'm pretty confident that among the 80,000 frames I have all the pieces of the moon as a whole.
What I'm now having issues with is how to break down these Avi files into frames which then can be used to create a mosaic. I need a "for dummies" guide ae thats what I'm feeling like currently.
Thank you in advance for any assistance you may be able to provide. :)
After many hours of fiddling round with Registax wavelet settings to process my own solar system images, I've always been curious as to how it actually works. In doing so I've put together my own image sharpening program which does something similar to Registax wavelets. For comparison, I've also added some general purpose deconvolution techniques which you'll probably be familiar with from other image processing software (like Wiener inverse filtering, Richardson-Lucy, etc). In choosing a point spread function to deconvolve with, one suprising result was that the typical stack outputs from Autostakkert work best with a Lorentz point spread function (with a minor modification). Deconvolving with a Gaussian point spread function doesn't really work. Deep-sky images seem to deconvolve best with a Moffat point spread function (which is to be expected - it's already well established that star profiles in long exposures are best approximated with a Moffat function).
On the whole, it's unlikely that you can sharpen solar system images much more in this program than you already can in Registax. You can see results from Registax wavelet (sharpening layers), inverse filtering (e.g. Wiener), and iterative deconvolution (e.g. Landweber) below. They all give very similar results. In all the techniques there's a similar trade-off between less noise but less detail vs more noise but more detail.
There are some quick start notes on the first page of the Readme here:
There are some examples of deconvolved images here (move mouse over image to see before/after):
Image credits are on the hyperlinks
The Windows download is here:
Example solar system tifs to experiment with are here:
And the project page is here (with Source code in the src folder)
If anyone finds it useful, do post here how it compares to other tools you use for solar system image sharpening.
The download and the source code are free, you can use it unrestricted for any purpose. The OpenCV and OpenCVCSharp components which my program use have licence information at the end of the Readme.pdf.
Recently I bought a ZWO ASI178MM for planetary/lunar/deep-sky imaging and last weekend i had clear skies so I was able to capture videos of the moon in two panels. I have already processed the videos in AutoStakkert, I used 3x drizzle because I intend to print the image so now I have two 120MB TIFF images that i would like to combine in a two panel mosaic. I tried doing it in Hugin, a free panorama stitcher but the program crashes due to the file sizes being too large. I have searched for tutorials on using DynamicAlignment in PixInsight but it seems to me that i'll need a reference image to be able to create mosaics in PixInsight. Is there any way to go about this, I feel like this should be a pretty straightforward job but I am not very experienced in PI so I would really appreciate some advice.
I tried using DynamicAlignment as you can see in the attached screenshot but the result was just a cut version of the target image, aligned perfectly to the source image. It would be perfect if it didn't cut off the lower part of the target image.
I have been really inactive here, so apologies.
Here are a few images of the Solar Eclipse, happened on 21 June 2020. It was annular, but partial from Mumbai region (around 60% covered). Maximum phase of the eclipse was at around 11:30 a.m. IST.
This is actually onset of our 4-5 months of monsoon season, so getting decent skies was a tough part. Luckily got decent cleared patches here and there with occasional rains.
I had to use whatever I had to make a comfortable view of the eclipse, thanks to the lockdown.
I simply took a box, made a whole of the size of the eyepiece on one end, cut the opposite side and attached a paper. I had to do little bit here and there attachments for perfect angle. But was really happy with the results.
One of the best experience was when I was seeing the Sun while it was drizzling at the same time.
