2026-10-09 APP 2.0.0-beta48 has been released !
This is mainly a bug fix release for the reported bugs in beta47. In addition it has a significant User Interface performance improvement noticable when you need to process 1000s of images in APP.
2026-10-03 APP 2.0.0-beta47 has been released !
This is a very big release... many code optimizations/rewrites, many parts of APP are much faster and more precise, especially star analysis and registration are much faster ! Big mosaics will go much faster 🙂
And we introduce a new preview filter, which includes the new Adaptive Deep Sky Stretch and a General Levels Stretch, this has been long over due. The old preview filter (the panel on the right side to stretch and preview your data) has not been updated for a couple of years and it is a critical part of any APP session.
Adaptive Deep Sky Stretch or ADSS is a much more intuitive stretch algorithm. It is also color preserving (which is a great new addition in itself ! ) which means that the highlights are no longer bleached, color is maintained from the linear data while stretching. You can simply stretch your data using the sky background level and signal width sliders which work much easier and more intuitive. You no longer need to fiddle with the old complicated sliders with zoom buttons. All the zoom buttons for the sliders are made redundant. And you can enter slider values in the slider value fields yourself. I will make a youtube video in the coming days to explain and fully introduce ADSS. Once the video is ready, it will be highlighted on the forum.
RGB Combine upgrade !. The RGB Combine Tool has been rewritten mostly. The tool is faster and easier to use and most importantly, the Luminance slider to inject a luminance channel or channels into the RGB composite is now working correctly. It no longer bleaches the RGB colors. Combined with the new ADSS preview, you will get much better and easier great composites with great color! I will also explain this in a new youtube video.
Hi Mabula
It would appear that your astropixelprocessor.com email addresses are bouncing back, I've tried from multiple domains as well:
I have been trying to reach out to get some data from you for my machine learning project of my masters

Dear Simon @stastro,
We are managing e-mail traffic ourselves with our own mail servers using the latest e-mail protocols with SPF, DKIM adn DMARC checks on outgoing AND incoming mail. If the e-mails bounce back, it likely means that the mail server that you use to send us email is not setup safely/correctly using the latest email protocols.
Which addresses have you used to send us email? What do the bounced emails report in terms of problems?
I did check our email logs and I can see this from you registered email address:
Feb 19 23:08:08 h2887425 postfix/smtpd[8882]: NOQUEUE: reject: RCPT from 143.ip-151-80-235.eu[151.80.235.143]: 504 5.5.2 <vps427074>: Helo command rejected: need fully-qualified hostname; from=<simon@stastrophotography.com> to=<support@astropixelprocessor.com> proto=ESMTP helo=<vps427074>
Feb 19 23:09:11 h2887425 postfix/smtpd[8882]: NOQUEUE: reject: RCPT from 143.ip-151-80-235.eu[151.80.235.143]: 504 5.5.2 <vps427074>: Helo command rejected: need fully-qualified hostname; from=<simon@stastrophotography.com> to=<mabula@astropixelprocessor.com> proto=ESMTP helo=<vps427074>
So your email server that sends on behave of stastrophotography.com is not configured correctly/safely.
I checked the DNS records for 151.80.235.143 in terms of any MX record and the required Reverse Lookup for any mail server. Both are not correct.
mail.stastrophotography.com does not point to 151.80.235.143 in DNS:
and 151.80.235.143 does not point back to mail.stastrophotography.com

Hi Mabula
I have also tried from my alternative email address which uses googles mail system, and again it bounced back, can you check for (simon at fleximiners dot com), but the question was as follows:
I am currently in the Machine Learning module section of my Masters in Computer Science, and my project is to take data and run it through specific machine learning algorithms, what I wanted to do is take the output of frame analysis and train the algorithm based on an acceptance or rejection of the image frame as part of a stack, I have not found anywhere in APP that allows me to export out the list. So I was wondering if you had any data exports you could allow me to use as part of my ML project.

With regards to the MX settings, I have checked my DNS records and it is set correctly, there is an MX record pointing to the correct IP, so this is a bit strange and I will look into it
Regards
Simon

SPF protocol check does not pass for sending email with fleximiners.com from a google mail server. If we would allow this, we would get a lot of spam I am afraid so we can not. Some mail servers would accept your email but it will be better if you can fix this on your side of you want to be able to deliver e-mails to any other mail server. More and more servers will start to reject your e-mails if the SPF protocol does not pass.

Hi Simon, there is no export button at the moment no, but please check the following:
Once all data is analysed after 5) Normalize, start an integration while you have the separate Console Window open.
That Console Window will show the statistics before the integration starts. You can easily copy/paste from the console windows to grab the data. I hope this helps for you purpose?
