Re: Use only flat correction: impossible??

Thanks for exhaustive explanation. So is that sharpcap effect normal if i use only flat correction? I didn't do any sort of stretching histogram, just use flat correction, as you can see in the live stacking screenshot here nodark_flat_screenshot.jpg So from your explanation, it isn't useful to use ...

Re: Brain giving strange results

In my situation bothr with lps idas filter mounted, and without it, the brain gives more or less the same result.

Sky brigthness measured with idas filter: 2-3
Without filter: 5-6

Brain suggest gain 120 and exposure 15-18 sec, with 10% read noise limit.

Re: Brain giving strange results

I'm interested too... Asi294: my brain suggests gain 121 and 15 sec....but if you use those settings, almost nothing appears. And even if you do a strong strecthing to the histogram, very few signal comes out. So i think something in the brain doesn't work properly... I repeated the sensor analysis ...

Use only flat correction: impossible??

While i was experimenting out the effectiveness of dark and flat, i found that using only flat frame caused an error. If i want to apply just flat frame correction (and not dark frame correction), it isn't possible. I show you my 3 final stacked image examples Dark, no flat. Yes dark_noflat.jpg Dark...

Re: Flats and mottling pattern in final stacked image

Thanks Robin for your useful tips. Before reading your message, i was out to try different live stacking with and without flat frame. I took flat frame at gain 200...and everything was perfect. Live stacking went smooth, flat applied correctly, and final stacked image was perfect. No more problems. ...

Re: Flats and mottling pattern in final stacked image

I've read all on the web about flats and how to do them properly, also your topic Blacwikkett, before posting here... You can read all my stuff in my signature.. I'm saying that the problem maybe flats taken at 0 gain because when i try to experiment 0 gain on my CMOS i obtained this final stacked i...

Flats and mottling pattern in final stacked image

Last time i used Sharpcap Pro i did a normal live stacking session, i took a 20 flat frames to have the final master flat: then i started live session with flat subtraction enabled, and my final stacked image was this, horrible, mottling pattern stacked_flat1.jpg stacked_flat.jpg So i decided to try...

Re: Dark and flat: checking live results during live stacking

Thanks, Robin. I thought that dark or flat correction is applied to final stacked image and not to every single frame. So when i will do the next test, i start a live stacking with some settings (dark and flat on) and leave it unchanged until final stacked image has been saved. Then i restart a new ...
