Jupiter again from 26th December without artefacts

[Ringrocket]

Hello,

I finally got time to retry my Christmas Jupiter. This time no stacking artefacts !

However, I can still see one or three dust bunnies on the image and the recording that are derived from something located on the chip. Now I wonder if these are really made of dust. Because when I start out with a clean chip and no bunnies on a cold night the next session they are alway's there. And I use a IR/UV block filter which I had not removed inbetween. So could this be caused by dew when I move back in my warm house ?

And it turned out that transparency changed during recording because of smoke from a chimney from a nearby farm and also mist. This sometimes caused me to use the wrong gain settings and at moments during a recording the equatorial region bleached out....

Two differently processed Jups (can't choose).

I also wonder if it is unwise to put Jupiter so far away from the center. With a star test i see that collimation near the edge looks less perfect than nearer to the center of the field ? But I can't help adding a moon too when possible. I just like them too much

great details, well done

Nice job.

They are both nice but I slightly prefer the first.

Keeping the Planet centred V not centred would be an interesting comparison. I think you would need a very good night and a well polar aligned mount to be fair though.

Crisp shots....lots of detail

First one for me, lovely clear image. SIMON.

Did you reproces in R6? Or did you revert back to R5?

I'm reprocessing last nights work in R6 and am getting some weird artifacts - looked like my screen had cracked....

Thanks everybody

I think the choice of pictures also depends on the monitor I'm using.

@Jarvo: This is in R5. Didn't try R6 again yet. The artefacts you describe sound exactly like the ones I showed in my previous thread.

On a Dutch forum someone adviced me to use fewer alignment points in R6 (about 5) and they should be within 2 thirds from the center of the planet and not closer to the edge of the planet in Registax 6.

Cheers,

Jeffrey

Stunning details!

Really sharp. I assume that was with the home set-up. Regarding the planet not being centred: do not forget that the size of the chip is very small indeed, smaller than the FOV of my Radian 8mm 250x. This means that all of the chip is effectively on axis.
