[Sticky] Combining R, G, B with Ha & OIII data using an Optolong L-eNhance filter  

@vincent-mod

It looks like once you have run all your data through the APP steps from load to integrate you can simply drop into tab (0) change the algorithm and then say Yes to the renormalising dialogue box.

If you then go straight to tab(6) and hit the Integrate button again APP will re-normalise and integrate the data using the changed algorithm. No need to clear and reload the image and calibration files

Yes, I think that's indeed possible. I simply kind of forgot about it as I rarely use this type of data, which I will now address. So thanks for making that quite clear. 🙂

@vincent-mod

The rotation works fine, however the stack artefacts will remain because there is no option of MBB when using the combine RGB tool (tab 9).

Today I also got several java errors during star an analysing (tab 3)….. All frames are calibrated but around 70% star analysis it gives the JAVA error. Never had this issue before…. Tomorrow i'll try again and will post the java error message.

thanks for your help.

Sorry to hear that Michel, APP 1.076 will have quite a few updates to the star analysis algorithm, it will come out as a beta soon. This week Mabula and I will be in London for Astrofest, I think Mabula will work to release a beta somewhere this week still but can't guarantee.

I too have been experiencing various Java errors when following the OPs workflow, sometimes during the star analysis and others in the normalisation. I discovered it was because I manually setting and forcing the Bayer CFA pattern under the '0 RAW/FITS' tab as I normally do for my standard integration workflow. By leaving the patten as 'supported' and the 'force Bayer CFA' box unchecked I no longer experienced the errors. 

Hi Vincent

I have followed your workflow precisely and everything has gone fine until I have gone to combining the 6 files in RGB combine and I got the java error.  I added each file and when I went to calculate, the error message appeared?

Are you able to give me any advice please as to how I can combine them?  I am running APP V 1.079.

Thank you

Well, that's a bit hard to judge without the data. Would you be able to send it to me to have a go as well?

You can upload some to our server (<- click that link) with username/password: appuser

Please create a directory called "julian-rgbcombine" and I'll have a look asap.

Thanks, Vincent

Thank you for posting this workflow. It is my understanding that what is happening here is that you're combining 2 sets of OSC data, 1 broadband RGB and 1 multi-narrowband OSC data. What if I wanted to combine e-Nhance data with true Ha and Oiii mono data? Would the workflow be the same? Is it even possible?

Of course, the optolong data that's where you use the "extract Ha" and "extract OIII" features. That creates mono data, Ha and OIII. You can then combine that with other mono data, if that's another set of Ha and OIII data then you just add that to the same set.

In assembling a 6-panel Mosaic, I'm hoping to be able to combine my NB (Ha & OIII) data from my L-eNhance filter with my RGB data taken with my OSC camera.  I have integrated all of the RGB panels and created an RGB mosaic, then split the channels into Red, Green & Blue files and saved.  I'm stuck at the NB filter files.  In step 6., (Click on Load (tab 2) and enter your lights, etc. for your L-eNhance frames and appropriate calibration frames.), do the NB files need to be the raw uncalibrated, unregistered files?  Or can they be calibrated and integrated into panels before extracting the Ha & OIII?

Thank you,

Dale

So what you want is to have the R, G, B data and NB data together and at least registered and normalized together. You can do the calibration on the RGB and NB data first and then it's not needed anymore when processing those frames together.

14. When registration is complete, click on Normalize (tab 5), click on Normalize lights. When complete, click on Save Normalized Frames.

I keep getting an error when I get to this point.

I would love to have a (new) tutorial of this... Because I understand that the first 'tutorial' has too many steps? Clearing and restarting isn't always necesary I believe? And what do I choose when combining all the files? There are many choises... RGBH00 ? And what does this have for effect? I'm new to working with APP, so maybe it's clear to other users but not yet completely to me 😉

Thanks, Arnaldo

Good morning,

I have been extracting Ha and O3 and re-combining this with RGB channels. My question is how to work with the “new formula” button and the pull down menu next to it.  

cheers,

Mark

Hoi Mark,

Select a new formula from the drop down and then click the button to apply it. You can see that it has been selected by the changes in the sliders for the individual channels.

HTH, Wouter

aha, so it are basically presets for the sliders and not a different algorithm in how the different channels are combined?

@ahbok

Using Trial ver APP & want to buy software if I can get this one thing to work:

I am trying to use this procedure to Get HA & OIII data from " ONE SharpCap DeBayered Live stacked Image using L-eNhance filter," with or without any calibration. 

It always crashes, I assume since I do not have RAWs to Debayer in APP.

Please advise if this is even possible.

rgds, CS & tnx, Mike

I think it's the source data, you should get the raw data to do this (or fits data that has been processed correctly). Don't use already processed data in APP as that might cause issues indeed.

OK - No problem & thanks,

I've tried Fits, RGB, Tiff, etc. Stacked SharpCap Live Capture images ................ all Non compatible with APP. I could capture unstacked RAWS but that is the point of " Live Stack " - you end up with one  Stacked & Registered Sub & don't have with in my case a few hundred 50MB Raws. tnx agn, Mike

Hi Mike,

if I’m not mistaken, there is an option in sharp cap where you can select that all the raw images of the stack are also saved. You can find the option in the live stack tab. 

cheers Mark
