It's a nice effort. Amount od detail and general processing is pretty good. What I doo notice however are quite a few edges from stitching. How did you put the mosaic together? Manually or with some specific tool? if you did it manually, you need to feather the overlap. Nonentheless a very nice image. Wouter.

Very nicely done 👍

Hi, I made a little overview of the different steps in lunar image processing. The image was made on september 20th 2019 during a night with good to excellent seeing conditions. First the capturing data: The image was captures with a CFF CC300f/20 classic cassegrain telescope. And a ZWO ASI 174MM camera at prime focus. As a filter a Baader orange filter was used. No additional optics were used. The image scale is around 0,2" / pixel. A total of 3000 frames was captured. The first image shown is a single frame randomly selected from the original 8bit SER file. By itself the above image is not bad. plenty of detail is visible and it's quite sharp. If you'd inspect it closely though you will see that it is full of noise. At the size shown above it's hardly visible though. First step in processing is stacking. I chose tot stack 20% of the frames. So 600 images. The main goals are: selecting the best frames, reducing noise. The result is quite dramatic. This step is indispensable when processing lunar images. open the image at high resolution tho see the difference. You will notice that overall more detail becomes visible. the next step is deconvolution sharpening. For this purpose I use a Lucy richardsonn deconvolution. I used, because seeing was really good a rather small blur radius of between 1.5 and 2 pixels and about 30 iterations. The result is that more details become obvious. Just know one thing. don't overdo it. Too much sharpening will introduce artifacts also be cautious that you do not start to sharpen the background noise. (that's also a good reason too stack plenty of frames.) final processing is done in Adobe Photoshop CC. Here the effect is most dramatic. techniques used are: high pass filters, unsharp mask, camera raw filter. during the first three steps of processing the impact might seem subtle, and in fact is it subtle. However without those subtle changes it would be impossible to get the effects from the final processing. also during the final processing you'd constantly want to keep an eye on how noise behaves. Sometimes subtle noise reduction in between sharpening steps might be necessary. I hope this little guideline will come handy. Clear skies, Wouter.

A fabulaus image. Certainly well worth the effort. Well done 👍

As usual, a magnificent series of images.

Some really good images. Well done. If I have to give a little point of critique.. Maybe the images are a tad dark. But other than that. Really good. Wouter.

Those are some nice and detailed pictures. Well done Wouter;

Lovely image.

Those look really good. Well done. Detail, focus all good, as well as excellent processing.

Very nice.

Loovely images. Well done!

Quite nice. Well done!

Very nice. 👍

My first image of 2020. Finally. Click thumbnail to view bigger image. image taken with My CFF CC300 f/20 asi 174MM in combination with a proplanet 807 filter due to bad seeing. Still plenty of detail is visible. enjoy.

Some great images 👍

sweet set of images. Thanks for sharing.

Groberts, music: equipment i used: CFF CC300 f/20, ASI 174MM, orange, Baader ir-pass, or astronomic IR-pass filters processing: autostakkert, lynkeos3, adobe photoshop. Wouter.

Hi, A little bit overdue; but here it is; a summary of my images made in the past year. I made many more than what is shown in the movie; But theser are for me at leats the ones that are most interetsing or beautiful; enjoy. Clear skies, Wouter.

Amazing images as usual. well done, Luc! Wouter.

A nice set of images; well done 👍 Wouter.

Very very nice 👍

A truly outstanding series of images. I'm always astonished by your work. Thanks for sharing, Luc. Wouter.

Very nice.. 👍

I am a bit behind on processing images. hHere's one that is a bit overdue. Click the thumbnail for full image. Enjoy the image. Feel free to share your comments. Wouter.

Quite a lovely image. well done. wouter.
