30 July 2020 - APP 1.083-beta1 has been released introducing Comet processing! This 1st beta has comet registration. The stable release will also include special comet integration modes.
9 July 2020 - New and updated video tutorial using APP 1.081: Complete LRGB Tutorial of NGC292, The Small Magellanic Cloud by Christian Sasse (iTelescope.net) and Mabula Haverkamp
2019 September: Astro Pixel Processor and iTelescope.net celebrate a new Partnership!
Hello Vincent, with the new beta version 1.75- Beta4 I can no longer calibrate my flatframes. There is a warning that the pixel dimensions do not match the dark flat.
With the version 1.74.1 the warning does not come and the calibration runs without problems. What I noticed was the following
APP does not create the masterflat with the same pixel dimension as the flatframes.
So I'm seeing shots of 1.074 only here right? Do you have one with the warnings?
Did you do anything different compared to 1.074 by any chance? Which camera do you use, color or mono? Thanks!
Hello Vincent, I hadn't actually done anything differently. I used the same workflow in beta4 as in 1.074.1. and the previous versions. So in 1.074.1 everything runs fine, from calibration to integration.
I use a ZWO ASI 294 MC Pro, this is an OSC camera.
Ok, thank you. I passed this to Mabula.
Mabula would like to get some subs if possible and also pixel dimensions of your sensor (so amount of pixels horizontal/vertical), is that possible for you? You can upload some subs to our APP server, with usernamd/password: appuser
Please create a folder with your name on it first. Thank you!
Okay I'll do.
Hello Vincent, I uploaded the dataset.
With best regards.
Excellent! Thanks, Mabula will take a look at it as well.
Hello Vincent, I might have been able to narrow down the problem. When I load the images into APP, the correct pixel dimension (Bin 2x2) is displayed.
As soon as I start the calibration the image size suddenly changes from 2072x1411 to 2072x1410 and there is a warning that the Master Bias and Master Dark-Flat frames do not fit to the flatframe.
In other data sets with pixel dimensions (Bin 1x1) 4144x2822 there are no errors.
Henry, thank you very much for reporting this and uploading your data with all calibration frame types.That really helped to solve this quickly.
Indeed, in the Beta was a problem with the MasterFlat creation having to do with Bayer CFA data that has uneven dimensions. I have fixed this now and it will work in the next release. I will create Beta 5 and it will be available later today or tomorrow so you can continue and process your data 😉
Your 2x2 bin frames have dimensions of 2072x1411 pixels, that means that your calibration masters also need to get that same dimensions.
APP 1.074.1 and before were creating data of 2072x1410 which worked, but now this will work without removing the final pixel vertically.
It's nice to be able to help.
And thank you very much for the quick feedback. 🙂
