i have amp glow that’s displayed in my processed subs that I can’t remove. Is there away to mask this prior to stacking/processing? It’s barely showing in pre-processes subs but when ran thru APP it’s amplified.
Hi Manuel, what camera do you use? Normally amp glow can be processed out by using the correct darks. What exposure time, gain and temperature were the lights and darks taken at?
ZWOASI294 PRO, 120g/300s subs/-10*
Yes that camera is notorious for its problematic amp glow. I have read reports of many users on several forums who were struggling with the amp glow produced by this camera. I am not sure how to solve it unfortunately. Maybe the ZWO forum can help you? In any case, this is not an APP thing but really related to the camera.
I’m currently redoing all my calibration files and will also make masters according to Sara Wager tutorial video. I will follow up afterwards. Yes, I’m aware of ZWOASI294 PRO reputation with amp glow, but my main issue is trying to process it out. I will also visit the ZWO forum. Thanks😊👌🏾
Good idea to redo your calibration files. It is very hard to process it out once it slips into your image integrations. I hope the new calibration files solve your issue.
After processing a picture this is the results. I have a huge spike in the upper right corner. I dont want to crop it due to cutting out the subject. The other picture is straight off of ASI AIR (non-processed). I've redone my master calibration files using Sara Wager's video tutorial and do not believe I've done anything out of order. This is killing me
So can you show a screenshot of what your masterdark looks like? And also check if the adaptive pedestal is on in tab 2, normally this is the case already.
I have the same camera and yes it has bad amp glow I would say but its easily calibrated out with proper dark frames. Just make sure your darks are the same temperature, gain, offset and time. APP does a great job of calibrating out this amp glow.
EDIT: Even if your exposure time is not the same, APP can scale the dark and still do a good job of calibration.
Yes, APP is indeed able to correct severe amp-glow as well, so I'm also wondering if the calibration data is correct.
Thanks Manuel, I'll have to look tomorrow (or maybe Wouter still is up 🙂 ). We'll try to get this sorted.
@mannymo63 Ok, to be able to investigate further, could you also share a single dark frame and a single light frame?
I believe I have solved the issue. My dark flat and flat files were in the wrong folders. I produced 2 subs that displayed with no amp glow so far. Thanks for your assistance.
You mean you loaded them in with the wrong buttons in app?
