Hi,
I'm trying APP, so I'm not an expert user and in general I'm not an expert in astroimage processing.
I shot 22 frames of Rosette nebula with my modded Canon EOS550D some weeks ago and tried to integrate them in APP.
Strangely, I found quite a few colored dot cluster in the integration result, red, blue, white, everywhere.
Could you help me to understand what's wrong in my stesps (default settings everywhere, 22 frames of 5 min dithered, biases, flats, dark flats, NO dark)?
Attached you can find the integration result and a detail with circled in white some of the dot clusters.
Thanks,
Alberto
Yes, I get that too sometimes. Not sure why either but I'd like to know.
Verwenden Sie die neueste Version von APP? Wenn ja, aktivieren Sie den automatischen Modus während der Integration. In einer älteren Version muss Manuel die Ausreißer-Ablehnung aktivieren, z. B. Sigma-Clipping oder Mad Sigma. Dann sollten diese Hotpixel-Cluster verschwinden.
Zusätzlich würde ich eine schlechte Pixelkarte empfehlen. 20 Dunkelheiten bei 300s mit geschlossenem Kameradeckel.
Laden Sie dann Lights Darks, Flats und Bias und überprüfen Sie bpm unter Calibration.
Kalibrieren Sie dann die Bilder neu und integrieren Sie sie.
Mit freundlichen Grüßen
V.1.075
I left everything default.
If I understood well, I have to try with the new version (I tried the download, buy It seems very very slow and doesn't complete).
I built a bad pixel map for a previous test, I'll try ti use that (but I'm dire there aren't so many bad pixel in my frames).
Come back with the results.s, thanks.
