Interesting capabilities of this little thing but unfortunately in 99% of the DSO Seestar images I ahve seen the stars all look like flat disks. No 3d effect on the stars

:(

Are you thinking the stars are too sharp? Too bloated? I haven’t noticed a huge difference in the stars that I used to get when I was doing serious DSO imaging and interested in how you mean the 3D effect.

The stars I see have a flat white circle and then abruptly end with a sharp border. That is not 3D as I imagine to see them. Look at the two ROI I cut out from an IMage I made a few weeks ago. That is how I imagine stars should look alike. OK, they could be better too but I have been out of DSO imagin quite some time and started again 6 months ago after getting the ASKAR 103APO.

Another thing which annoys me in a lot of DSO images is the perfect black background which I think is nearly impossible as there are a huge amount of stars between us and the end of the Universe which are there but we can not resolve them so space IMHO is not Pitch Black :mrgreen:

IMHO

Below the full Image of Arp 214 @560mm focal length. from where I took the ROI. I know there is a blue gradient on the right with which I have been fighting as I have them in nearly all my images and a friend and I have been discussing about this and I came up with the possibilty there is something wrong with one of my Blue filter. I just got a new Player One Poseidon with a new set of filters and I will see how it behaves on the same ASKAR 103APO @560mm

Rainer, I think I am starting to understand what you are talking about now.

In the same way we try to get a 3D look at our Day star aka Sun we shpuld try to get 3D stars also Suns In Deep Space Objects IMHO. OK, if we eliminate the stars from DSO images then there is no problem :mrgreen: as some do...

OK, I think my last post with the galaxies in B&W exhibit the stars you are thinking of. I think it may be in the processing as people are trying to bring out as much as possible with very little integration time and may be over sharpening the stars. I always treat the stars separately from the object.
