Processing Planetary Images: Sort, Stack, Sharpen
Вставка

- In this video we are going to process images of Jupiter to reveal loads of fine details - using freeware.
The approach is to use a high speed camera to capture thousands of frames of Jupiter, reject those blurred by the atmosphere, stack the good ones and then sharpen them to bring out all the surface details.

Excellent tutorial and image Mark thanks for sharing your work mate
Cheers Anthony.
Great video Mark. Thank you
Thanks Craig.
Thank you! Very helpful!
Mark this is what I admire about you! You do it for the love of Astronomy! and want to share the knowledge You are like me trying to help better the community!
Thank you for your kind words, Steve. Looking forward to meeting you next weekend!
Excellent tutorial
I will try this
Thanks
Have fun
Amazing
Thanks
Great Video Mark. Your tutorial videos Are Fantastic. I look forward seeing Your workflow on Mars. Especially with Softwares like 'Winjupos'. I used the Cartography tool 'Lambert equivirectangular projection. Though It doesn't really show much Detail, perhaps the Resolution of my mirror limits it. Cartography with Jupiter is Pretty cool, in Fact I want to Compare how Jupiters Surface changes in Just One Year!
That would be a great project. Have you measured the size of the GRS? It’s really shrinking now isn’t it?
Wonderful. I hope to see more videos from you Mark. Have you reviewed any new cameras?
HI Craig - thank you for your kind words. I have my new Player One Saturn-M. Very pleased with it for both solar and live stacking. The problem is the venerable ZWO ASI224MC still works really well so I am loathe to spend more money upgrading when the old kit still works fine.
In meantime, may I ask what camera you have?
@@RefreshingViews I have the ZWO585MC. I haven’t tried mono
Thanks nice talk through.
10mS exposures and grainy images?
So a big aperture 480mm f6.7 cdk would give less noise?
Equipment didn't develop over last 20 years as I hoped. DIY telescope covers too small area for current affordable camera sizes.
200mm secondary is going to reduce advantage of large primary, but is it worth finishing and mounting?
each frame at 10ms is grainy but of course 1000-off 10msframes stacked together are not so noisy. Good luck with your CDK project - a 480mm scope sounds wonderful!
I am just starting on my planetary imaging journey and I have all the gear assembled. I also have a grasp of the processing steps. I am unsure on one aspect of it and that is the capture format. Is it RAW or AVI etc. Thanks Mark.
Hi AN - thank you for your message. You definitely want to be shooting in video (rather than 1000s of stills). I would suggest using SER simply because that’s what the pros recommend. That being said I’ve not seen any loss in quality using avi format. Defo video, ideally SER if not then AVI.
Nice capture. Am wondering how 'seeing' is defined by actual seeing (as in actually captured, rather than an estimate using a 'clear skys' weather app)?
Good question! From reading online professional surveys measure the distortion of an Airy disc. As for forecasts I guess they correlate the turbulence and wind speeds in the upper atmosphere.
How did you get such a large Jupiter? My 16" is using a 2.5x barlow at F20 with a 2.9 micron pixel camera, but yours is almost 50% larger, when comparing mine in AutoStakkert. What resolution did you shoot your SER video? I was shooting 1024x768 at over 186 fps and got over 15k frames in 90 seconds.
Hi Mike although it is hard to know with a moving primary mirror, I think I am around f22 or so with my barlow spacing and 3.75um camera pixels. I use the Region of Interest to reduce the image size (something like 600x600 px from memory) - this increases the frame rate down the USB and reduces the file size by not recording empty black space.
@@RefreshingViews Thanks for reply, I think my ser video content is my problem, and noticed from your worst SER frame that mine looks that way all throughout video. Amazing how well your skies are much better than where I live, Midwest in US.
@@mikemurphy7711 - don't forget I only show the good ones in rare patches of high pressure otherwise you'd be looking at blurry images all the time!!
Have you used AstroSurface? How do the results compare with Autostakkert and Registax?
Hi Jon - I have yet to use AstroSurface but it is on my list of things to look at over Christmas break. What about you? Have you used it?
@@RefreshingViews yes, after failing to get good results with Autostakkert and Registax, I found AstroSurface to be much easier to manage, and I've got some nice results for Jupiter and Saturn so far.
Well explained Mark were you a teacher ever as it seem simple to do?
Thank you for your kind words - that’s the beauty of editing! It is relatively simple - although a lot of astrophotographers do like to up the complexity to bring out the last smidge of detail.
Are these planets with 12” scope? Barlow?
Hi - it's with a Celestron C11 and x2 barlow at f20. Further details are in here: ua-cam.com/video/hsADl8tnOFo/v-deo.html
@@RefreshingViews Great! I have learned processing from your videos, only difference is that I take pictures by Sharpcap.
I never get resolution on C8 like yours, despite having well better conditions in Texas. Thus, autostakkert shows more quality frames. I could go up to x3 Barlow. But, your outcome is better.
So, scope size could be important contributor.
