2019 September: Astro Pixel Processor and iTelescope.net celebrate a new Partnership!
Is there a manual from APP?
A complete manual in PDF format is not yet available, but I am working on this with high priority.
Adrie, APP is really simple, just load all your frames, set settings in menus 2)-6) and click on Integrate in 6) and APP will do the rest.
Have a look at this tutorial, it will show you how APP will automatically process multi-filter data including calibration:
Please let me know if you have additional questions,

No, as that will be announced clearly on the site. I have no ETA myself, @mabula-admin should know more about that so I tagged him.
Those new videos on the APP Vimeo account are very useful! However, I was wondering if there is going to be a PDF user manual? Even if it was just a current collection of pop-up information boxes it would be a nice reference.
@bbhtaylor : maybe something like this will be ok ?
[['DDP Saturation Threshold (SAT.TH): adjust DDP saturation background protection thresholdThis is a percentage of the data range. If your background (peak of the histogram) is at 15% of the histogram, you will protect the background by setting this value a bit higher than 15%, for instance at 20%. This slider is very usefull to apply saturation to nebula, galaxies and stars, while preventing the injection of unwanted chromatic noise into the background. Only applicable to colour data and if the saturation checkbox is enabled.Left image: the linear data stretched with auto DDP and saturation SAT at 20% and the threshold SAT.TH at 0%Right image: the linear data stretched with auto DDP and saturation SAT at 20% and the threshold SAT.TH at 25%, notice that the main object and the brights stars have the same color saturation, but that the background is more neutral by having prevented the injection of saturation in the low light areas of the image.']]
It's not well formatted but I don't have so much time ... if there is someone who can script in python (3.8) the output can be improved for sure 😉
Here is the script:
from bs4 import BeautifulSoup
for filename in glob.glob('*.class'):
html = open(filename, encoding="ISO-8859-1").read()
soup = BeautifulSoup(html)
table_all = soup.find_all("table") f = open('output.txt', 'a')
for table in table_all:
output_rows = 
for table_row in table.findAll('tr'):
columns = table_row.findAll('td')
output_row = 
for column in columns:
Hi Vincent, would it be possible to include a release date for each video? Something like:
04-Dec-19 : This tutorial consists of 9 parts and is a complete tutorial from loading the raw filter data to a final LRGB color image ready for publication and includes all processed data available for download.
