Support@Seestar Could you please provide an update on this banding & artefacts issue?

Support@Seestar

Seestar will introduce flat field correction in the future to solve this problem.

oRX2hR4h

Support@Seestar Excellent. Is it possible to estimate when this might be released?

Nawal

Support@Seestar was the flat field correction introduced in the latest firmware update 2.4.1? I’m still experiencing the banding issue as others describe.

the message I received was for next month

I'm hoping the update will help with this. I just now noticed as I've been shooting Nebula alot and its not appearing in these images. (Mosaics)

Myke

BTW, this is without LP filter.

Graxpert.

Yeah, I have similar issues. It only shows up when shooting WITHOUT the LP filter. IE, it shows up when shooting galaxies. Here is M51 from last night. This is the processed jpg produced by the Seestar itself.

You can easily see the 2 vertical bands on each side of the galaxy.

NavierIsStoked
Normally this would happen, it's due to reflections and will be resolved later by leveling the field.

Myke

Do what with GraXpert?

Brille

Myke GraXpert is an perfect (and free) tool for background extraction (and a lot more). Background extraction helps flattening any kind of banded or blotchy background. Give it a try.

Myke

Brille Will do TY

Myke

Brille It Kinda helped, but still had odd halo around galaxy and stars with GraXpert.

I'm glad I ran into this thread. I have terrible banding on galaxies in my highly light-poluted skies, so much so that I don't even try to capture them any more. Good to hear there may be a solution.

cyberdanny And EQ mode magnifies this situation. One suggested solution/workaround is to use 1.1 Framing. This will cause the sensor to shift slightly averaging out the noise. In ALT/AZ mode, since the object is actually rotating on the sensor this accomplishes the same averaging.

Credit for this workaround goes to other users on Cloudy Nights. It worked quite well for me on a two hour EQ exposure of M81/M82....
