May 27 2026 APP 2.0.0-beta45 has been released !

Fully Multi-Threaded LNC, many improvements for the registration engine, platform upgrade, and further tuning of internal memory consumption and memory release back to OS.

Apr 14 2026: Google Pay, Apple Pay & WeChat Pay added as payment options

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.

 

What am I doing wrong? Should be simple quick answer for any who might know

for APP forum

I wanted to do a 'quick' stack.

I loaded 28 frames from ZWO 2600 mc pro.

I loaded 30 Flats and 30 darks.

Lights and darks are all Gain 100 Exposure 120 seconds.

Flats via auto-mode of the 2600mc pro were 5.9 seconds.

After loading I clicked on integrate and I get a warning about

masterdarks/masterflats.

OK I'm new to all of this and truthfully don't know how to shoot masterdarks or masterflats.

I would have thought (with a little googling) that APP would have done the math on the

masterdarks/masterflats or done some work around.

I'm trying to get away from DSS but if I dumped these 3 sets of files into DSS I would have had

a file output.

Help please.

It's basically saying you're missing Dark Flats or Bias.
It would still work, but probably get a better calibrated Integration if APP was able to subtract the some inherent noise not already removed (bias) or the noise from your Flats (with DarkFlats).

For flat calibration you either need bias or darkflats with the same settings as your flats.

Thanks you two for helping.

I have discovered my error I think. I'd changed targets and upped my exposures to 5 min's....but used the prior targets darks which were 2 min's. 

I say I think because I then threw it into DSS and it stacked them anyway.
