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.
I've been using APP last years using mono camera shots (asi1600mm & asi294mm) with great success. Lately I changed to a color cam (omegon vetec 571c) but my integration results are a failure. Below some examples:
The first one is a single shot, the second is the integrated one of 40 shots. I use darks, flats and darkflats. Settings on APP as usual with auto options prefered. Same results in an other try:
Any idea what has gone wrong?
Could you explain what exactly you describe as a failure? The first lighter ones seem to be stretched a bit more and don't have flats applied. The other ones are stretched less (and thus darker), but seem to lack in color. Can you tell me what your setup is exactly and what settings you used during capture? What workflow do you have for the calibration data?
Hi Vincent. Failure I mean the results are green where they should not be. As a result I cannot bring colors properly in natural. Double cluster set is with skymax127 & vetec571c, 90sec gain100 -10oC. Andromeda set is with esprit100 & vetec571c, I think 300sec gain100 -10oC. The first ones are stretched & uncalibrated from asistudio viewer. The stacked are only in 10% stretch setting.Â
I'm suspecting either an issue with calibration data or the green may be normal as an OSC has more green pixels on the sensor. Did you check what happens when you go through color correction?
Vincent I switched back APP version from 1.083 to 1.077 and all has come to normal. Below a stacked double cluster. Comparing to above stacked the difference is obvious. There must be something with the last verion I cannot figure out.
Might be, would you mind sharing your data including calibration data? That would allow us to investigate, thanks for the update:
So analyzing your data now. I do notice that you're shooting at 90s only and looking at the histogram data is lost in the background. When I look at your flats, they don't seem right, the histogram is almost absent when switching off stretching (unstretched it should be at around 50-70% of your dynamic range). So these definitely need some work as having wrong flats will impact your data in the end. I'm also not able to correct the star colors properly in the end, which may mean that the respons of the sensor is not giving a proper broadband signal, are you using special filters maybe?
