tbird Posted December 10, 2013 Share Posted December 10, 2013 Taking advantage of the excellent seeing last night here's Jupiter and Europa. Celestron c9.25 / NEQ6 / QHY IMG0H / Televue x2 barlow 60 second AVI, captured 2500 frames in Firecapture, reduced to 2000 in Pipp and then best 1000 stacked in Registax 6.

dawson Posted December 10, 2013 Share Posted December 10, 2013 Nice Paul. Lovely big image. Loads of detail. I'm still learning about planetary imaging, but yours looks a bit like one of my old attempts (but yours is way better!). I found that my sensor was filthy, and for some reason the stacking software was trying to stack/align (not sure which) on the dust on the sensor, and not using the data from Jupiter itself. I get that feeling a bit from your image, as though there is a faint veil in front of the image. Looking closely there are a few lines which I've tried to indicate in the image below; I'm not sure if these are artefacts from stacking, or from artefacts on the sensor itself. Have you done any "flats" to see yourself if there are any obvious dust bunnies / other artefacts? Mine weren't visible when looking at the sensor with a magnifying glass, but when I looked at a diffuse white light via the laptop I could see hundreds of them. I've still not effectively cleaned them off. Just a thought, and as I say I am no exert on this, just telling you my story in case it helps you get crisper images. Why only 60 seconds of AVI? You could, I believe, get 3 minutes or more without any planetary rotation causing trouble, and this would triple the number of frames you could stack which might help with sharpness / clarity. But smashing shot. I just need better seeing and a better back. James Link to comment Share on other sites More sharing options...
catman161 Posted December 10, 2013 Share Posted December 10, 2013 Great detail in that shot Paul. It was cleanish here last night when I got back from dinner with a couple of friends and I thought about maybe getting the scope out but there was a lot of high haziness as when looking at the moon it had a hazy halo all around it.

oldfruit Posted December 10, 2013 Share Posted December 10, 2013 Excellent result Paul, probably one of your best to date. Link to comment Share on other sites More sharing options...
tbird Posted December 10, 2013 Author Share Posted December 10, 2013 Hi James, there's is some dust on the sensor hence the artifacts, unfortunately I'm unable to shift it using the blower and I don't want to use any more aggressive means to clean it. The reason I was only doing 60 secs was because the polar allignment was a little off and I was capturing ROI, Jupiter was drifting off the screen. TBH I was in a bit of a rush to see what I'd got, I've got a disk full of avi's to process and a Moon mosaic to do yet Link to comment Share on other sites More sharing options...
tbird Posted December 10, 2013 Author Share Posted December 10, 2013 Maybe pushing it scaling the image up, this version probably a bit nicer Link to comment Share on other sites More sharing options...
oldfruit Posted December 10, 2013 Share Posted December 10, 2013 Yes, agreed Paul, the reduced size version looks better. Link to comment Share on other sites More sharing options...
dawson Posted December 10, 2013 Share Posted December 10, 2013 Ah yes, that looks really impressive now. Much crisper Yes, grubby sensors are a pain; mine is still bad and I'm unsure what to do with it. Felix swears by cans of compressed air, so I may give that a go next.

+Ibbo Posted December 12, 2013 Share Posted December 12, 2013 Very nice Paul a small nuclear device gets rid of the dust bunnies, downside the EMF wrecks the sensor I use a rocket blower, but it takes at least 3 attempts, attempt 2 usually puts more crap on Steve Link to comment Share on other sites More sharing options...
