Mar 28 2026 APP 2.0.0-beta40 will be released in 7 days.
It did take a long time to have the work finished on this and it will have a major performance boost of 30-50% over 2.0.0-beta39 from calibration to integration. We extensively optimized many critical parts of APP. All has been tested to guarantee correct optimizations. Drizzle and image resampling is much faster for instance, those modules have been completely rewritten. Much less memory usage. LNC 2.0 will be released which works much better and faster than LNC in it's current state. And more, all will be added to the release notes in the coming weeks...
Update on the 2.0.0 release & the full manual
We are getting close to the 2.0.0 stable release and the full manual. The manual will soon become available on the website and also in PDF format. Both versions will be identical and once released, will start to follow the APP release cycle and thus will stay up-to-date to the latest APP version.
Once 2.0.0 is released, the price for APP will increase. Owner's license holders will not need to pay an upgrade fee to use 2.0.0, neither do Renter's license holders.
Hi guys,I can't get my separated OIII and Ha images amp glow removed ,even with darks and flats. When I select HA one shot colour it subtracts the amp glow but ,not when separating OIII and Ha channels.any suggestions would be appreciated and thanks
I use the asi294 colour camera
@liverpoolfc Assuming that you use an L-eNhance or L-eXtreme filter with an OSC, the best way to separate Ha and OIII is to select Ha-OIII extract Ha in tab 0, load your lights and calibration files in tab 1 and then click integrate in tab 6. When APP is done, return to tab 0 and select Ha-OIII extract OIII, return to tab 6 without making any additional changes and click integrate again.
@wvreeven hi Wouter,I appreciate your help,that is how I originally seperate the two channels. And your right about the filter. I’ve watched a few videos on it. I also selected the reduce amp glow option.
Sorry Wouter, did you mean not to do steps 2-5 , just go from 0,1 and then 6?
@liverpoolfc Yes that's what I meant. If you go straight to step 6 then APP will perform steps 2 to 5 automatically. No need to execute them manually.
Thanks again, I’ll give it a try
Hi again, I tried the first H a extraction and I noticed it didn’t come up with a final integrated image. It highlighted one of my lights which I assume best image but I didn’t see anything in the image to indicate a calibrated finished Ha extractions photo.
Well I got the oIII image and it still hasn’t extracted the amp glow. I used darks too. Like I said it seems to subtract them when I choose ha one colour option
@liverpoolfc Can you please upload your data to
https://upload.astropixelprocessor.com/
using upload for both username and password? Please create a folder called liverpoolfc_amp_glow and put all data in there. Let me know when the upload is done by using the Reply button so I get notified by email. Thanks.
@liverpoolfc Donald, the flats are not flats but lights of 240 sec. Are you sure you uploaded the correct subs? Please delete the "flats" and upload the correct ones. Thanks, Wouter
@wvreevenoh I’m sorry wonder who f that may be a part of my issue
@liverpoolfc If these are the only "flats" you have then it may very well be. Do you still see the amp glow if you only process with darks and leave the flats and dark flats out?
Yes I still get the amp glow with only darks, How I originally processed it I had the flats later after I couldn’t get rid of the amp glow. And like I said it seems to erase the amp glow when I choose HA color ,it’s only when I split the two channels ,OIII and Ha,that I can’t seem to get rid of amp glow.
@liverpoolfc That seems to indicate that the darks are good enough for Ha but not for OIII. That's strange.
@wvreeveni know,Its when I separated two channels Ha and the 03 , both the Ha and O3 show the same amp glow ,it’s only when I do Ha color option that it removes the app glow and that is really strange
Can you post an example of how your OIII integration looks like? I gave it a try as well, without flats there is quite some vignetting and it looks like the OIII signal is a bit on the low side, so a longer exposure will help you here as well (OIII is weak so try at least 5-6 min per sub). Personally, I'm not seeing much amp-glow here. I loaded all lights, darks and darkflats using the Ha-OIII extract OIII algorithm, checked to see if a single light was corrected properly and that seemed to be the case and the integration, apart from a bit low on signal, seems ok?
Second I did an "Extract Ha" and also this shows some low signal in the single subs, bit higher gain, longer exposure also there is needed. I'm also wondering if your offset needs to be higher, do you know what is normally used for your sensor? Maybe try 40 next time as well as I seem to be getting clipping in the final integration (black pixels).
Hi Vincent , I’ll send the images through to you later today. Thanks for your help
FYI my offset was 30
So I meant to ask Vincent were there any special parameters you changed in any of the processes that maybe I may have missed? I did make sure that remove amp glow was checked but ,if there are any other parameter changes you can recommend as yours did turn out without any glow,I would appreciate it. Thanks
Hi Vincent , I have uploaded an OIII extracted HA image and and HA extracted image. If you look in the top right you’ll see the amp glow. Hopefully you can see what I may have done wrong. The fact that you were able to use my data and not having club makes me think this could be a parameter issue anyways I would love to hear your thoughts on it and thank you for your help
No, nothing special. I used beta-2 of APP 1.083 and loaded in your lights with the algorithm in tab 0 set to "HAOIII- extract Ha" or "extract-OIII" and then made the calibration masters without touching any other setting. That just seemed to work.
