Flat frames
How many flat frames do you take?
I have read evrything from 200 to as many as the lights.
In my other thread i made 500 flat frames, but the light frames were a stack of 5000, which i felt was not enough.
Any advise for a newbie?
Thanks.

Re: Flat frames
Not more? I use them in autostakkert, and thought i would need a lot more than the 500 i took.
But when i take a video with 5000 frames woulden't i need a lot more flats, at least to create a master flat.?

Re: Flat frames
I generally don't both with them, but on the rare occasion I do, I use a stack of 50 in FC.
Why do you want to take flats?

Re: Flat frames
Easiest way is just to clean the chip!

Re: Flat frames
I thought flats were for night-time imaging and have never done that with Solar-imaging, but then what do I know...
As Mark says about cleaning the chip, or even better don't let the dirt/dust get into any part of the optics !!!

Re: Flat frames
35 s acquisition x 150 fps = about 5000 frames ;-)
This is only for narrow field imaging. The trick is to move the field of view of the telescope during acquisition.

Re: Flat frames
Yes, but you don't have an uneven field, so just clean the dirt off the chip... Definitely the easiest way to do it...GKA wrote: ↑Thu Apr 29, 2021 9:33 pmWell i saw this video , and this guy take seriously great pictures , and he uses flats , so i guess there is diffrent opinions.EGRAY_OBSERVATORY wrote: ↑Thu Apr 29, 2021 7:30 pm I thought flats were for night-time imaging and have never done that with Solar-imaging, but then what do I know...
