Announcing Ekos Live #34031
Peruse the feature suggestions at your leisure:

Unfortunately the posts are not tagged as EAA or AP but most are EAA in my opinion.

Announcing Ekos Live #34033
Jasem,

These are my observations of EAA vs AP. Please accept my apologies if anyone reading this is offended by my assessment.

Practitioners of AP approach their craft like they would reading a fine novel. It is something that is generally done in private. Practitioners of EAA do things in public and seem to relish large audiences. It appears to be a social media phenomenon.

Somewhere it must be written that devotees of EAA must never consider exposures any longer than 15 seconds even if it can be shown that it can dramatically improve their images. You will be rejected outright by suggesting such heresy. As a corollary to this fact the followers of EAA always end up under-utilizing their equipment. In my opinion they need an f/2 scope to get decent images at 15 seconds.

All must be accomplished in real-time or near real-time according to EAA. This means that the process of capturing, stacking, and Photoshop-like processing must be done incrementally as the stream of image data arrives. Also important, all must be accomplished within one application or perhaps multiple applications that are seamlessly connected.

EAA people tend to spend gobs of money on their equipment because they are constantly under-utilizing it. In my opinion this is one big reason why manufacturers push EAA so hard: it enriches them.

Thanks for listening.

Jasem,

Here is a list:

* Capture to a single color channel.
* Live Stack post processing.
* Color balance. Simple RGB sliders to correct color balance independently of the camera settings.
* Automatic noise reduction.
* Sharpness adjustment.
* De-ringing.
* Saturation adjustment.
* Histogram slider buttons – improve appearance.
* Color correction for 8 and 12 bit RAW, use the 12 bit mode for live stacking and get realistic colors.
* Drift graphs, allow undock and pin. Button to reset and clear.
* Use live stack offline.
* Auto flip for meridian change.
* Option for display controls, apply to individual frames.
* Overlays and drawing tools for broadcasters.
* HDR stacking.
* Auto white balance button for live stack histogram.
* Live stack notepad.
* Window color for live stacking.
* Remove the last stacked sub-image in case of an airplane, satellite etc.
* LRGB live stacking.
* Live stack, automate ‘save’ every X minutes.
* Undo last frame from stack.
* Clean video without menu or borders for video broadcast.
* Save as viewed to include display histogram.
* Gradient removal in live stack.
* Log feature for live stack histogram to adjust sliders.
* Map controls (especially the histogram and color balance controls during live stacking) to programmable keys on the keyboard. For EAA would be so nice to change the histogram without fiddling with the mouse.
* Live Stacking could be made to present a color (or false color) image built up from multiple stacks from different filters on a monochrome camera.
* Live stacking there is an option to save the individual frames, but at the moment all the frames are saved. Would it be possible to have the option to not save frames discarded by the FWHM and Brightness filters.
* Automatic hot pixel removal during stacking.
* Save drift to log when live stacking.
* Annotate the processed image.
* Fine color adjustment in live stack.
* Include the stacking quantity and the total stacked time in the bottom bar.
* Gradient slider in the live stack histogram.
* Undo last stack.

I am wondering if there is any progress on Ekos for EAA like features.

By "EAA like", I mean that there are many definitions, and the one a few comments up from here is just one of them.

For me, "EAA like" means that I mainly observe from a desktop remoting into a laptop that is connected to my AP capable mount. However, I don't do any post-processing or stacking of the images I take. I don't have the skill for this, nor the time. I am happy with observing images as they come. I don't guide, and am able to take 3 or 5 minute images that way (the key is OnStep as a mount controller. Check it out, it is worth the effort. Also, check my album of unprocessed images ).

My setup is built with KStars/Ekos/INDI at its core.

If Ekos can do some stacking, and stretching to get better images, that would be a welcome addition to the tool kit. Something like what SharpCap does.

Any progress on this, without the need to do it on the internet?

I believe Robert experimented with some live stacking features before, but nothing was added to KStars yet.

Do you think this is something you can work on? We can help you to get started in KStars development :-)

Although I have been developing software for almost 35 years, these areas (image processing, GUIs, ...) are not something I enjoy.

On the other hand, if there are utilities that I can script into a command line interface, I am happy to do it.

For example, I wrote a time lapse script, and used it for Comet 46/P Wirtanen , and Comet Iwamoto last winter.

Obviously, stacking is not that simple.

Alright, I'll get started on this soon then since it's a quite popular demand.

Wow Jasem!

Thanks a lot.

I found some focus stacking stuff, which people who take macro photos use. It can probably be repurposed for a rudimentary command line tool.

Basically it is like so:
# Convert Canon RAW to TIFF
dcraw -T something*.cr2

# Align the images
align_image_stack -v -m -a aligned something*.tiff

# Stack them
enfuse --exposure-weight=0 --saturation-weight=0 --contrast-weight=1 --hard-mask -o result.tiff aligned*

I have yet to try it. Need a clear night to take say 10 x 1 minute exposures, and try to stack those.

But since what you will write will be integrated right there from Ekos, then here is my suggestion: start with a very simple scheme. Perhaps just stacking and stretching. Put it out in the field to get it tested a bit. Then based on the feedback you can choose to refine it or declare that 'perfect is the enemy of good enough'. Inspiration from SharpCap would be nice, since it has some following.

hi
if you are interested with live stacking stuff, you can have a look at this :
www.indilib.org/forum/development/5204-a...ro-live-stacker.html

Alpha branch tested at the moment includes many new features, as new developpers are now involved
Fell free to play with it

Gilles,

Thank you for the pointer. This looks like exactly what I am thinking about: stacking automatically without user intervention.

Jasem,

This may be all the EAA folk need. Perhaps not well know because not much in English is available on it (just guessing).

Let us hear from users before re-assessing whether to integrate it somehow (proper Debian package with dependencies will help with the install), or write something new ...
